ok im thinkin bout changing my cam, right now its 570 610 236/244 on a 112, and done good so far, but now im upgrading some stuff and lookin to see if there is anything to gain by switching? im stayin hyd roller and still have a stock comp so 7k rpm will be about the limit!

 

112 sounds pretty narrow for a turbo cam. Talk to comp cams.

 

or cam motion

 

I'm running something to the tune of 248 254 650lift on a 112 in a 370 motor with an 88mm. Depends on the setup. On the street it would be a bore. At the strip with a transbrake and a 2 step it works well.

You probably already have enough cam to make it to 7k assuming the heads and 76mm will get there.

 

heads are ported afr 220's flow 330, and the turbo is s475, for not. bout to put a 88mm wheel in it!

 

I probably wouldn't go any bigger then unless you are aftermarket pcm. The above setup I have trashed ls7 lifters and made power to 8200.

I have a 475 75/83 going on my little lt1 and am curious to see how it acts. Stick shift street car though.
