Could this be done with a stock bottom end and stock LT1 head (ported) and a HR car and the car wight in the 3400+ range

What kind of cam would have to be made here...i would like spec here ....

Any outher info would be great here as well....

 

Id say 375 tp 400 horsepower to trap that mph
decent set of heads and cam should get you there with boltons

 

my car made 427rwhp weights in at 3695 and runs 118 in the 1/4 so to break 120 you need to be lighter or have more hp.

 

You need weight reduction.

I believe there are many liberal dynos out these days. For example...

A friend's Z06 dyno'd 380rwhp at MTI with headers and other boltons. His car weighs ~3250 with driver. He trapped 116 on an 80* day at Houston Raceway.

My car dynoed 318rwhp on a dynapack dyno, weighs 3550 with me in it, and I trapped 112.5 on a similar day at the same track.

So, it is hard to say what rwhp number you will need. Depends on your weight and where you dyno .

there is a lot more to how much power a motor makes other then peak dyno numbers. power curve, torque and so on.
