My new motor is fully machined and balanced. It is a 355 sbc with a forged gm crank, eagle H beam rods and TRW forged pistons. The compression ratio is 12 to 1. I'll be running a solid crane nitrous grind cam with 114 lobe seperation 500 520 lift 248 258 duration at .50. I will be running AFR 210 heads, using a vic junior intake and a 650 double pumper carb with a proform main body.

I will be running a 250 shot with the edelbrock rpm kit.

Last year I ran a 11.25 @ 122 on a 150 shot and that was with a much milder motor and TFS 23 degree heads.

What do you guys think I might run?

A friend of mine has almost the identical motor with the only exception being the camshaft and carb and with a 250 shot with the edelbrock rpm kit he ran 10.07 last year.

I don't expect to go that fast but perhaps mid tens? BUt I really don't know?

 

That thing is going to want to spin some RPM. I am going to say that your car could run as well as 11.5's with a larger converter N/A (which may not be optimal for nitrous) and probably down close to 10 flat on the bottle. Who knows, it may break into the 9's .
