GT Engine Combo
 

I have a 68 camaro I am considering running in super stock. I am wanting to run it in one of the slower gt classes, is there a good combination for a 350 in one of these classes because I already have a short block.

Thanks Chris

We have a 69 Camaro we run in Super Stock. We looked really hard at running GT, for 2-3 months, and we found that the 1st generation Camaro really doesn't have too many competitive GT possibilities.

Why not build a 295/350 and run it in a traditional class? With factory heads, it's only factored at 317HP, and runs at 9.44 pounds per HP in SS/GA. I doubt you'll find a different 350 that will run competitively in GT.

Put a 305 in it

Re: GT Engine Combo
 

1970 350 big 2bbl, small chamber heads , 250/233 GT/MA..11.75 index... Low enough for you?

Re: GT Engine Combo
 

Mark - Is that the combination Mike Town races? I know it is a 2-bbl engine.

Re: GT Engine Combo
 

I forgot about that combo Mark.... That would be a good one. Chris if you don't want to run a 2bbl then Adger is right go with a 305.

Re: GT Engine Combo
 

I can't remember which one, but one of the fuel infected 305's was way under rated at one time.

Re: GT Engine Combo
 

Dwight , I think so. The 69 is 233 also .Obviously stuck with that with a 69 body.
Somebody got the 70 hit a little, so it's out there somewhere.


Adger, All the 305s are beat up pretty good for GT.
Other option for GT/MA is the 283. As long as one is not afraid of rpm's, that'll work too.

Re: GT Engine Combo
 

Was the 69 with the 441 head only?

Re: GT Engine Combo
 

Yep. 1970 2 bbl (only) is listed as 441 , but smaller chamber.
It is what it is,..like a 459 intake on a 283 ,right?

1983 165/230 305 TBI
Cam is a little short as a stocker, good heads, no idea about the induction, but it uses a 2 hole TBI with 1.8 dia per hole. I'm sure it would work well on a SS type intake.
1989 220/235 305 PFI fits both stick and auto
I like the 1983 TBI

Re: GT Engine Combo
 

The 305 "dish" combos are not all that bad.

Re: GT Engine Combo
 

So to recap 3 possibilitys for a 350 flattop SS shortblock
1. 300 / 320(ish) many head #s
2. 255 / 294 Quadrajet {441 heads 69 model only }
3. 250 / 233 Lrg. 2 brl. .............."

Re: GT Engine Combo
 

Actually, the O/P said "one of the slower GT classes", so I have been focusing my recommendations in that direction.

Re: GT Engine Combo
 

I wonder what the cfm of that throttle body is . Anybody know, or know where to look?

Re: GT Engine Combo
 

Mark,

I have an airflow test on just about everything, not sure who did the test but here is what they stated for TBI:

TBI 574.1 CFM complete, 584.7 CFM w/o injectors.
