Dudeman Posted November 18, 2011 Report Share Posted November 18, 2011 Howdy! I've pretty much just lurked on the site for a while and figured it was about time I posted some pictures of my truck. This is the '79 620 I got from DatDoug a while back with a basically stock L20b (Weber and a header), a really straight body and pretty decent interior. Basically a great driver/platform for future mods. Since getting it I have added V6 2wd HB front brakes and rebuilt the stock steering and rear brakes. Now its pretty effin scary in the wet... can you say threshold braking? I recently bought a '73 for parts so now the poor '79 has to sit out in the cold and rain till I have room... Spare Matchbox Dizzy is always good to have Nice wheels and tire setup. 225/50ZR15 will be way cooler than the 205/60's on it now Excited to install this and see what kind of difference it makes And a couple A87s I've collected since getting into Datsuns... Working on getting this spindle off for Str8_69. I'm pretty busy so if you're patient I'll just give it to you for the cost of shipping The '73 had an L18, but the pistons in that engine have less dish than the other L18 pistons I have, and I'm not sure what exactly they are. The pistons in the truck are almost completely flat, and they have .75 stamped in the top. Bore measured with a cheap steel gauge was 85mm. Pistons in the truck's L18 Pistons from other L18 I haven't cc'd the pistons, but can perhaps someone can shed some light on this... Oh yeah and we can't forget Tarzan and Bedframe Quote Link to comment
izzo Posted November 18, 2011 Report Share Posted November 18, 2011 Cool man was wondering when you were going to post this stuff up. Quote Link to comment
Dudeman Posted November 18, 2011 Author Report Share Posted November 18, 2011 I'll also be willing to sell some parts if people need 'em. I've got basically the whole truck sans motor, plus some other odds and ends like a super nice late style grill (oxymoron, I know). I don't need to sell anything bad enough to like, start a for sale thread or think of prices or anything crazy like that, but if there's something you need that I don't really really want to keep it will probably be cheap.

metalmonkey47 Posted November 18, 2011 Report Share Posted November 18, 2011 WOW. That truck is nearly perfect Quote Link to comment
Rockatansky620 Posted November 18, 2011 Report Share Posted November 18, 2011 I'd be itnerested in the headlight assemblies, minus the lights themselves. Quote Link to comment
]2eDeYe Posted November 24, 2011 Report Share Posted November 24, 2011 Found it. :D That red truck is sweet. I might be interested in some drivers side suspension parts. I'll know more when I get mine torn down. Quote Link to comment
Rockatansky620 Posted November 30, 2011 Report Share Posted November 30, 2011 Ian, just want to say thanks for the headlight buckets. And consider this some seller feedback. For two boring little headlight buckets for my 620, this was the nicest packaging i've seen in ages! I constantly buy hot wheels and vintage action figures on eBay, and this realy blows me away! Thanks for the extra effort man! Quote Link to comment
Str8_69 Posted November 30, 2011 Report Share Posted November 30, 2011 Don't know how I missed yer thread, that 79 is sweet man! Quote Link to comment
datzenmike Posted December 1, 2011 Report Share Posted December 1, 2011 The only difference between L18 and L20B pistons is the dish size. L18........ 4.36cc....... 85mm diameter L20B.... 11.36cc...... 85mm diameter Excited to install this and see what kind of difference it makes The first thing you will notice is a reduction in body roll in the front. The hood will remain more level during sharp steering changes. Adding a sway bar where there was none before or stiffening an existing sway bar will tend to reduce oversteer and or increase understeer. You may notice that the front end does not turn into a corner as well as it used to. There is a feeling the the front wants to plough straight ahead. Most vehicles are designed with slight understeer because it's easier to correct by the average (or unskilled) driver by letting off the gas and applying the brakes. This will shift the weight forward increasing tire traction and helping to turn the truck. If your truck has some understeer, adding a sway will increase it. Find a level empty parking lot and drive in a circle while slowly increasing the speed. If the rear tires break loose first and start to 'come around' you have oversteer and a front sway bar will help reduce this. If the front end breaks loose or the front end is not turning where the wheel is pointing then you have understeer and a sway bar will only increase this. Not saying you can't use one. There are many many things that affect understeer/oversteer. If the sway bar increases understeer you can counter that by running larger rear tires, softer compound, softer rear springs......

Dudeman Posted December 2, 2011 Author Report Share Posted December 2, 2011 Holy Crap thanks for the responses everyone! datzenmike I appreciate the heads up, as the truck definitely has the tendency to understeer. My 620 isn't my daily right now so I'm going to throw the sway bar on there anyway and will have to stiffen up the rear a little bit (and ad more power!) before I really drive it. But I like the idea of performing a before and after experiment to see exactly what happens... I put the new wheels and 225/50ZR15 Goodyears on today and they are definitely more aggressive... they stick out past the fenders and I don't know if I like that, but the Toyota 4x4 wheels that were on there before are really heavy, and to me lightness and contact patch matter most. I will have to do some testing to make sure they don't rub... I'm curious to see which setup you guys think looks cooler though cause I can only keep one set so shoot me some feedback I'm getting pretty close to doing the motor and have always wanted to run an L18 with flattops and a peanut head (~10:1 compression) because I wanna rev the crap out of it :D But I'm considering putting L18 pistons in the L20 with a peanut head (slightly higher compression IIRC), and eventually I will be adding coilovers up front. Dunno what I'm going to do about the rear end though... I'll also be wanting something slightly larger than the 32/36 so when I have the monies I'll be on the hunt for a 38/38 or single Weber sidedraft or set of SU's or something Quote Link to comment
]2eDeYe Posted December 2, 2011 Report Share Posted December 2, 2011 I like the stock car look, but if you lower it any more you will get into the fenders. I have a set of basket case SU's that I won't be using...? :) Quote Link to comment

pharouh Posted December 15, 2011 Report Share Posted December 15, 2011 Nice! :wub: I like the wheels you have on it now. Get some center caps to set them off. Why is it you guys get parts trucks that are better than what I'm trying to fix up? :crying: Quote Link to comment

Ya one of them is torn down...I ended up getting a set of webbers so I never finished messing with them :rolleyes: I do have a manifold to go with them, not sure about the linkage. I have a hoist, it is either in Northgate or Everett but I can track it down if you need it. :) Quote Link to comment
Dudeman Posted February 15, 2012 Author Report Share Posted February 15, 2012 Howdy again! Seems like I never have enough time to work on my truck or post on Ratsun so my visits back will be sporadic. Olderdat I'm gonna be sticking with the 32/36 for now but if I decide to go that route I'll keep you in mind. And Str8_69 I've made a few attempts to get that damn spindle off but I think I need a bigger hammer... :blink: Gonna try to get it this Thursday tho. Good news! I just got brand new 280ZX flattops, oversized stainless valves/guides, and a reground cam for the L18 I'm going to build! The Pistons are ITM which is a cheaper Taiwanese manufacturer but I trust that they'll hold up The guy I bought the stuff from didn't really know anything about the cam, but it clearly has a longer duration than stock and "282" stamped on the end. It came in a Delta Regrind box that says 280 duration and .467 lift, but I'm not sure if the box is original to the cam I bought. If it is it'll be little better than stock.(shitty camera phone fail) Now though I get to move on to finding a machine shop to bore the block, install valve guides, etc. but I don't have any experience doing this. Anyone have recommendations in the greater Snohomish County area? I'd definitely prefer someone who knows these motors... And Redeye if you track down your hoist I would definitely use it and give you beer or something... And I would totally buy/trade for your SU's... Thank you all for your replies!

Laecaon Posted February 15, 2012 Report Share Posted February 15, 2012 Where did you get the flat tops? I would ideally want some .040 overs to get a 87mm bore, but anything would be awesome! Quote Link to comment
Dudeman Posted February 15, 2012 Author Report Share Posted February 15, 2012 Got all this stuff on craigslist, guy was really nice and had more stuff for sale including an A87 Peanut head. .040 pistons are part# RY6134-040. I got .020 pistons with .040 rings (a really nice set) so I'll have to get new rings... Quote Link to comment
Dudeman Posted June 1, 2012 Author Report Share Posted June 1, 2012 Slowly but surely I'm collecting the parts I need for my motor build. This Just arrived yesterday... Got her cleaned up, ports hogged out and big stainless valves installed He said he took about .025" off to get it level, but the casting mark is still visible so I hope it won't affect compression too much. I'll have to do some maths later.... Next is cam selection. These grinds look good for a streetable (but not DD) screamer, but I love hearing other people's suggestions/input http://schneidercams...0_Fdatsun4.aspx http://schneidercams...4F_datsun4.aspx Also I'll repost this picture, it's a mystery cam I got that I'm unable to find any solid information on. If anyone knows anything about it please let me know, as I would love to use what I have already but won't install an unknown cam in my motor. (Sorry for the crappy pic, the stamp on the cam reads "C 282") Quote Link to comment
