mainer311 Posted May 18, 2018 Report Share Posted May 18, 2018 Datsunparts.com has speedo gears. They're listed for a 5 speed, but, you'd have to look at the pictures and see if they would fit. http://datsunparts.com/Transmission-5-Speed Part numbers 2740, 2741, and 2742 As for the alternator, ignore Hainz. Get a high output one from a 510. It does fit. 1 Quote Link to comment
Crashtd420 Posted May 18, 2018 Author Report Share Posted May 18, 2018 Factory stock tires were 25.5" diameter Well that contradicts what I was told last year..... I was told they were around 24".. well if i compare a 25.5 tall tire to what i am running the tire size calculator says at 40 actual speed is about a 38mph so I'll have to consider that with my choice.... I was reading that I would need the purple 21 tooth with 4.37 gears,.... so with the tires I have i am thinking a 20 tooth would get me right where I need to be.. 1 Quote Link to comment

I did find one full assembly for sale with a red gear... I need to measure what I have to compare... Would be nice if the 19 was enough i could buy just the gear but I still think 20 is what I need.... And what year 510? That was still external regulator right? 1 Quote Link to comment

Factory original tire. http://www.bluehandsinc.com/uploads/4/4/3/5/4435437/stock-tire_orig.jpg I believed you the first time... I don't know where 24" came from... At least i know now to add the tire size variance to the equation.... 1 Quote Link to comment

Thanks I'll check that out.... I need a wheel bearing hub assembly for my chevy and they have good prices for that part... with 270000 miles i' m not spending alot to keep it running... plus I've done the expensive ones too and they fail just the same.... 1 Quote Link to comment

At least i know now to add the tire size variance to the equation.... Everything I read/found about OE tire size on a mounted stock wheel ends up at 24.8". When I measured what I had when I first got my 521, OE sizing everything...less than 25". 195/65R15 on a 8 inch wide wheel is 24.8". 1 Quote Link to comment
mklotz70 Posted May 19, 2018 Report Share Posted May 19, 2018 The tire in the pic is a bias ply tire....the original spare. I thought I remembered them being a bit taller, but I take lots of pics so I don't have to rely on memory! LOL I'm pretty sure they were 6 ply tires. Just looked at the pics again.....yep...6 ply. . If that radial were a 70 series, it would probably be just right. 1 Quote Link to comment
Crashtd420 Posted May 20, 2018 Author Report Share Posted May 20, 2018 Well i put the new muffler and tail pipe on, try not to shake your head to much... This is when the ratrod part of the build is gonna be showing up more and more.... 1 Quote Link to comment
d.p Posted May 20, 2018 Report Share Posted May 20, 2018 Noooooooooo!!! Stacks are the abolaute worst and without a diesel blowing black smoke what the point? Quote Link to comment

Crashtd420 Posted May 20, 2018 Author Report Share Posted May 20, 2018 I never have a point to the things I do..... why build an L16, why all the switches and gauges, because why not? It's more fun to ratrod/madmax it out, it was never gonna be all original so I figure why not do what I want.... any thing is reversible and the floor is so rusted with hole what's one more.... I actually wanna do a square stack in the end as a kick back to our square exhaust ports of the cylinder head.... Atleast it not on a trailer.... 1 Quote Link to comment

flatcat19 Posted May 20, 2018 Report Share Posted May 20, 2018 I say let him keep cutting holes in a 521. The more damage he does to his, the more the value of mine goes up. 2 Quote Link to comment

Just cranking up Dp with the trailer comment, needed to add an extra zing... And the stacks ideally would be 2 square tube stacks, a set on each side, one though an exhaust cutout and the other through the muffler... i saw this once and it got me thinking.. 1 Quote Link to comment

I was just going through your thread. Love it. I could not load up your video how did the dyna turn out. I’m doing a small engine build on my wagon. Check it out. All stock 1800 with ITB’s and crank trigger. But burning oil so got a 210 head but all reworked and now either a L20 or mother 1800. Going to Canby this year. 1 Quote Link to comment

Crashtd420 Posted May 21, 2018 Author Report Share Posted May 21, 2018 The whole dyno thing was more of an adventure getting there because of the snow.... the dyno itself was boring.... It was only there to get the timing set and to break the motor in, and cam in... I prepared for an appocolips with bags of spare anything i thought i might need... I needed nothing, the engine ran, i think the only thing I had to do was a quick clutch pedal adjustment but that was it.... basically just drove at different speeds and rpm for half hour and letting the engine compression brake a few times.. I needed the professional because I had no idea about detonation and pinging so I needed to know if I had to shut it down.. luckily it hasn't been an issue.. 2 Quote Link to comment
Charlie69 Posted May 21, 2018 Report Share Posted May 21, 2018 With all the hole cutting is your truck getting lighter in weight? 1 Quote Link to comment
hobospyder Posted May 21, 2018 Report Share Posted May 21, 2018 Negative, he is making up for the lightening holes with some badasss exhaust stacks 1 Quote Link to comment
Crashtd420 Posted May 24, 2018 Author Report Share Posted May 24, 2018 Took the truck to work today 22 miles, First time on the highway, other than the fact that I was going 60 mph at 4000 rpm all seemed real good.. I guess I need to get working on that 5 spd swap.... Quote Link to comment
