Jason H Posted January 16, 2019 Author Report Share Posted January 16, 2019 1 hour ago, paradime said: With the 510's trailing arm rear suspension it's very different from the Fords. When you say change caster a bit, are you talking from the top hat, or extending the trailing arm? Did you mean camber? I think what Suffergen was talking about by adding toe is Byron and Datsport (AU) both make adjustable rear trailing arm brackets that enable toe and camber adjustments. Although I know the 510's suspension very well, by no means do I profess to know anything about flat track car suspension setups. There was a group of guys here who converted a flat track 510 into a budget enduro car. When they tore it down, here's what the found: The front right had multiple springs and strange spacers. The left rear spring was about half the height of the right rear spring. The right rear shock was adjustable, and the rod cover was removed. One of the front struts (I'm thinking the right front) had the top hat modified for camber and/or caster. https://ratsun.net/topic/73011-swamp-thing-jbc-enduro-car/?do=findComment&comment=1532000 There was also a response from someone saying: left rear lowest ,, right front highest to counter the dive as you hit brakes and go into corner. if you go out to short track you will also notice every tire is a different size and tire pressure also.. that's why there is also a rule how much camber the right front can have cuz guys will extend lower control arm and try to almost lay the right front tire parallel to the ground if there wasn't. Hope this helps. Yes, I meant Camber right rear. Yes, I understand frame heights and will be checking them. Also gotta weight the car to get the rite percents on the scales.. I am hoping by cambering right rear, it will tighten car on exit. As the tire goes up, the tread will lay into the track more. Make a better contact patch.. Quote Link to comment
paradime Posted January 17, 2019 Report Share Posted January 17, 2019 Cool, you can find how to threads on slotting the rear crossmember, or get those brackets so you can adjust. Quote Link to comment

Stoffregen Motorsports Posted January 17, 2019 Report Share Posted January 17, 2019 (edited) You can slot a stock crossmember without any other mods, but the cool way to do it is by cutting off the mounting tabs and welding on slotted (and thicker) tabs for easy adjustments. Troy Ermish sells slotted crossmembers. Hey Paradime, haven't you ever seen Days of Thunder? A turn here, a wedge there... ESPN has excellent coverage. 510's are bad about dynamic toe change, which makes them, like an air cooled 911, tail happy. I was always very careful to stay on throttle in the high speed turns like 10 at SPIR and down the hill at Laguna Seca. But in the dirt, I could see that as a positive attribute.

I want to build a bigger replacement motor. I always go all out on my motor builds. Always, good rods, balancing, etc. Spend a few hundred now, or replace motor sooner. I am trying to get ideas on back up motor.. Like I said earlier about it being a custom motor, it will take more than just blueprinting and balancing. Getting the right combination of parts and massaging them all to fit together is custom engine building. Sounds like you know what you're doing already. 1 Quote Link to comment
docbainey Posted January 17, 2019 Report Share Posted January 17, 2019 This guy has a 79 510, solid axel car, (first post) its gunna be kinda hard to slot the crossmember! But it is common to add camber on a solid axle circle track car depending on what kind of axel your running (floater). For the class he's racing in (Holley 350) a first rate carb will set you back $900 bills! Circle track guys are in a different world then the typical road racer. 2 Quote Link to comment
bananahamuck Posted January 17, 2019 Report Share Posted January 17, 2019 A 79 510 (A10) has a solid rearend with coil springs. .. it isn't independent rear. . Quote Link to comment

docbainey Posted January 17, 2019 Report Share Posted January 17, 2019 Jason, FWIW, there was a guy that posted on here a lot that circle tracked a 510 wagon (solid axel). Holley 350 and all that good stuff. Maybe search for his thread. 1 Quote Link to comment

Now is the next motor. My car has independent rear. So it might not be a 1979. Quote Link to comment

Watch the vid he posted of his car and it's a PL510 he's talking about. Now that I think of it, how about some picts of this car? Aren't we a bit remiss in our demands these days.

docbainey Posted January 17, 2019 Report Share Posted January 17, 2019 The only car in the vid that I recognized was the Pinto. The rest look like there from the cartoon 'Wacky Races'. Something fundamentally wrong turning the steering wheel to the right to go left. Just my 2 cents. 1 Quote Link to comment

docbainey Posted January 18, 2019 Report Share Posted January 18, 2019 Jason, does your car specifically have to weigh 2100# or any car/engine type/chassis combo In that class have to weigh 2100#? is your weight established by engine displacement and engine type, ie pushrod, sohc non crossflow, crossflow, dohc etc?

Jason H Posted April 20, 2019 Author Report Share Posted April 20, 2019 Here is me on practice day. I was told at track car could be a 1969. I am new to Datsun. I know allot about the Ford stuff. I am looking to build a custom motor to get more horsepower. I was thinking KA24, because of rod length. Ford's can't come close. For the camshaft, I am thinking the schneider .662ish lift. Obiviously biggest valves I can, maybe 280zx valves? Porting and polishing, long tube header. It looks like I might do the stroker build. With aftermarket rods. Does anyone have parts laying around that are good, they wanna sell? I need block and good head to start with. Single overhead camshaft. Also need a good crank for stroker build. We are allowed to go up to 2600cc. Quote Link to comment
Stitebunny Posted April 20, 2019 Report Share Posted April 20, 2019 Sounds good! that is the most unlooking 510 I have seen in a while though! Quote Link to comment
Stoffregen Motorsports Posted April 20, 2019 Report Share Posted April 20, 2019 That has got to be the ugliest 510 I have aver seen. What's up with that front end? Motor sounds good. Suspension looks tight. 1 Quote Link to comment
