Building an '86 camaro. Gutting the car, everything from the entire interior (except one seat), unnecessary pumps (AC, power steering), fiberglass hood Only additional weight is sub frames and the 180 lbs that I weigh.
4 bolt 350, 10.5:1 compression, performer? airgap manifold (idle-5,500 if that's performer I can't recall), mild cam (off the top of my head I think it's 284 duration .458 lift), and 106 octane fuel. Got 11.5 inch wide slicks in the back and 215's in the front. 4.10 and posi, turbo 350 with a shift kit and ratchet shifter.

Let's see how close I am with my guess... I say 12.6-13.0
Estimated times?

 

What kind of heads? Why 106 octane if you are running 10.5:1 compression ?

 

Hump heads off a 305, 106 octane might be overkill for the cam swap...

 

I hafta guess 13s, corrected to sea level. a 200-4R, a 3000 stall converter, and better heads would be close to or in the 11s, still without nitrous. Now with nitrous, you should start in the low 12s, then just add some AFRs and that should be low 11s.

 

that is a small cam! You would gain nothing by putting 106 octane in the tank. I have 10:8:1 compression and run premium pump gas and works perfect

 

With that small of a cam you can't do much....106 octane might actually hurt you.....I run close to joe's at 10.6:1 and run pump gas just fine as well....also if you have heads off a 305..that's probably your worst killer right there...305 heads do not flow very well. What size valves are you using...what is your head runner volume??...stuff like that really makes a difference. I would say 13's, maybe mids at best...it's hard to guesstimate 1/4 times.
