Goin for build number 4 and i have a few questions if you guys can answer thanks in advance .. I want to do a mild or close to high build on the M90 ( i love the whine) Is3 or 4 Blower Cam and had a few questions. Lower intake manifold wise would or should i port the GEN V LIM to match my Stg 3 heads with 130# Springs? Ive heard from a few guys that porting the LIM to match the Heads would increase the airflow... I want to have as much flow as possible as far as lifters .. Should i upgrade lifters or stay with stock lifters? e85 on a 2.8 no lower.. I just wanted to hear you guys take on the this thanks again!!!
 


Is3 or xpz cam. I'd go with 150# springs. You could port the lower if you think it needs it. Either stay with stock lifters or ls7 lifters.

Is4 is too big of a cam. It is poorly designed for our heads, it sounds cool, but you will end up building a quicker car with an is3.

Is3 and xpz will make similar power, but the xpz idles a lot smoother, which is why I chose it for a daily driver. However for a toy or track car, you may want something that sounds meaner.

I'll tell you the top end surge of the thrasher cam I had was awesome.

But it was a choppy bastard. And shook everything. And broke things.
