IHRA Pure Stockers?

[Joe Toller]

Any advice for someone looking at this class? The car in question is a 70 Firebird, 400/2bbl (265hp), puts it at 13.00 in the books and a F/PS.

Any suggestions on the 2bbl? The combo in general?

i'm also very curious about this class for next year. What class would a 68 camaro 327/275 auto fall into ?? and where would you find the spec's for the factory 327/275hp cam?? what trans would i need to run PG or turbo 350 ? Looking forward to trying to put something together for next year.

IHRA will have the specs for the older combos,I would say anything 86 or older they will have cam specs because they used NHRA specs and NHRA specs had duration,overlap,
and spring specs till 86 at least.

IRACEITALL,
If I could have 4bbl combo I would try to do that,2bbl is harder to make work and weather will affect more.

If car was 2 speed then you will have to use glide if was three speed then can be 3 spd just remember can't have manual valve body.
Sticks and autos run together might as well go stick and have fun
I would try call IHRA office and see who can answer your questions used to be Mike Baker, Hank Blakenship could tell you(he's does'nt work@ office) or I say Terry Bell still remembers

NIX on the 2bbl, run the QJet 4bbl version.
Lot more tuning parts available.
A popular Car and similar period car Pontiac racers can sell you one already set up.

You most likely be running D/PS instead and having more fun.

Any tricks or go-to guys for the TH400? I dont find where I could use a TH350...

I would check and see I think as long as oem type trans and no manual valve body and 3 spd.

Automatic shifting T350 with 400 would be a good combo.
