12's Possible with my new engine?
I'm running a 383 stroker, LT4 Hotcam on 1.5 rr's, ported stock L98 heads, dual 2.5 exhaust through flowmasters and edelbrock tes headers (1 5/8 primaries), LT1 Converted manifold, and my own tuning on the eprom, 2500 ACT stall (I think thats the brand name), but i have 2.77 gearing and and a 700R4 to follow. Just curious if its possible. I haven't had much time to do a whole lot with the car as its been in for a make over (the last time i'll ever park close to another car). And i had the Speed Density swap going on, amongst other things. So hopefully this spring i'll get to take it out to the track.

There is a guy running 13.15 @ 104 with a stock gta-350. Based on his times I would say hoping for 12's is conservative. I also get the impression from most people on this site that mass air is not good and speed density is where it is at . Sounds like you are in good shape.

I have not used the hot cam. 4 or 5 friends have and they were all pleased with the results. One guy has a 96 vette grand sport. Stock motor with intake, head porting and a hot cam ran 11.82 @118.
