355ci 10.0:1, Mildly ported vortecs-studs and guideplates, RPM airgap, 236/246 .510/.512 crane cam 85 iroc 5 speed 3.73s? Also, anybody have an idea of kind of HP it'll put to the tires?? I'm thinking about 320-350rwhp.

I guess u will have to find out, let's us know

anywhere from high 11's to mid 12's depending on many factors...

I have a smaller cam, same motor setup somewhat, 5 speed, 4.10 gears and DOTs and ive gotten a best 12.56@110 .

high 11s to mid 12s just like was said earlier. i have basically the same combo, can't wait to try it out this year and see how it does.

Thats what I want hear. High 11's. I will also be using a set of Hedman longtubes with an X-pipe. The car is the sought after '85 IROC-Z 305HO-Also its Silver, very RARE. I already have the cam from a previous 406ci. The motor will actually probably stay at 350ci. Stock motor from 98 Suburban. I acquired this motor for the small price of $50 from a friend who had to replace it do to spun rod bearing. Another buddy has an extra crank-1-piece seal. An older friend of mine, he is like a grandpa, will help me cut the guides down, cut the spring pockets, and install studs and guideplates. I will do a bowl-blend and port match, and John will also do a 30-degree backcut on the valves. I will probably try some 1.6 rockers for a .544/546 lift.
Eventually a gforce T-5 too.

I would like to see 115+mph. at least 113-114mph.

your car is why I want to do this.

Same setup, smaller camshaft and went 12.28 @ 111.85 on street tires. What does your car weigh with driver?

I dont know yet. It has yet to be assembled. I am still acquiring parts. I am dealing with my ZX-11(spun a rod bearing last year) that I am putting the motor back in. I also have a 93 5.0 LX in need of tubular K-member kit(bent control arm, daily driver).
