ok heres the deal, I want to make my car run at least mid to low 11s on motor up here @ 5800ft altitude(forged and studded 10:1 355ci)....im running 11.8x-11.9x with a 125 shot right now(can get more with some traction and a/f ratio tuning). I am about to do a cam/heads upgrade here shortly, right now I'm running the comp NR288HR and edelbrock rpm alum. 170cc/70cc heads with an air-gap manifold and a 750dp. I'm planning on getting a set of patriot's full CNC ported "super street" heads,195cc, 2.02/1.60, 64cc combustion chambers. Coming down to 64cc from 70cc should bump up the CR to around 10:6:1 and then i'll match that with one of the two custom grind cams that I spec'd out(will probably still shoot a 100 shot to it):
238/248 dur @.050, .540/.550 lift, 110LSA
242/248 dur @.050, .555/.565 lift, 112LSA

The heads are good to .575" lift.....I drive the car regularly on the street so the extra tight lsa's won't work out too well, so i'm looking for the best street/strip compromise here. So, am i on the right track and are my goals possible?

 

You want to run low 11's on the just the motor? How fast is the motor now?

 

what did the car dyno at. if your running high 11's your full of it not with out being boosted not up here. im running low 13's with 350hp at the rear wheels to get in the low 11's that thing will not be streetabe at all and have to put down at least 450 to the rear wheels.

 

read the post and you'll see mention of the 125 shot... and if you're not running at least high 12's with any decently built 383, something is horribly wrong.

 

on motor, it ran a best of 12.97 but it'll average 13.18-13.2x all day.
