Hello everyone,New to forum and dirt racing. I am building a 85 tbird and would like to hear from any other ford racers who have experience with fox/tbird/cougar/mustang etc. for 3/8th mile high bank dirt(hobby stock). I have a 71 302 and c4 and am planning on running a 96 stang front from the spindles out w/ a 88 tcoupe rt. control arm and 8.8 axle w/ 3.73 gears and a lincoln locker Some of my specific questions are...
What spring,shock and struts?
Wheel offset/air pressure?We have to run 27-8-15 hoosier so no tire changes other than psi
What was the highest stall c4 converter available stock and what camshaft would work best. We have to wun 2 bbl. holley 350 on 2v intake with stock exh. manifolds.
Any other tips or tricks would be greatly appreciated! Except recommending running a chevy. I didn't get a blue oval tattooed on my chest in the Navy to be like everyone else!

i've got an '89 mustang with the later spindles, controls arms, etc. like you're building. it is a very capable car and a front runner. you have to drive them with some sense though.....if you start beatin' and bangin' with 'em, you'll come out on the losing end of it.

i use stock replacement struts, 15:1 GT rack with a 2:1 quick steer, a 1100 on the RF, a 1000 on the LF, a 225 on the RR and a 250 on the LR with heim end racing shocks on the back. this is with a 351w set back to #1 plug to lower balljoint and a 3000 lb. minimum weight. i have about 52% on the rear.

thanx os17! What about fuel line? Should I keep the stock line and just use braid from cell to line and from line to carb or should I do the whole thing in braid? If so what size would you recommend?Also, still looking for c4 converter info.

with the airflow restrictions mandated by your rules, a 3/8" line should be plenty. we have virtually unlimited engine rules and i use a 1/2" line with no problems. save yourself some money and use rubber push-lok hose and fittings.

good luck.

I'd like to see some pixs if possible. I am thinking of getting a kit from crc and tying the subs w/ 2x3 box. Any suggestions?

i used 2x2 square tube. i peeled the floorpan off of the top to expose the "frame rails". i hammered the 2x2 tubing into the factory frame and welded it up, connecting the subframes as well. you will have to cut and fit the tubing to the frame. it sounds like a lot of work but it's not that bad.

dirtybird, PM me your email address and i can email you some pictures of the frame. i would save the cage kit money and purchase a bender. simply put.....instead of "buying a fish", buy the "fishing equipment".....then you're set for a lifetime of fishing. a cage kit probably will not fit the "new" frame rails correctly anyway. every car you build will be better than the one before. when you get 5 or 6 under your belt, you will be building some awesome cars and other guys will take notice.......and who knows, they might ask you to build one for them.

no stock ones available that i know of.......you need 5"x 9.5" racing springs and about a 1"-2" spacer on the front.

I called tc racecars today and the guy said I needed 5 1/2 x 12 springs. The class rules say stock springs. Please clarify

the guy at TC is wrong. a 5 1/2" diameter spring will not fit the lower control arm spring seat. a 5" is what you need. a 12" tall spring might be okay.......a little taller than i like on the LF though.

you want the lower control arms level or slightly lower than level at ride height. get an offset bushing kit to raise the rack and pinion. this will help correct bumpsteer.

Anybody have a good way to take that sound-deadening material off the insideof the floorpans. I heard if you can freeze it w/ dry ice or co2 you can hit it with a hammer and it will break off. Anybody tried this method?
