CAM QUESTION

PI cams are def best bang for buck

Comp cam makes a xe268H for NPI apps that makes good power and maintains great drivability and owners compliment. I recommend a PI intake with that tho.

I do not mean to thread jack or anything but its stupid if i posted another thread about head swaps. Whendoing a full PI swap what is the safest most aggressive cam to use with a stock bottom end so there is no tapping? I searched already and nothing came up

CMS stage II N/A's is about as far as i'd recommend. I've heard of people using xe270ah's as well - but with less success.

That's a good question. The answer to your's lies in where you want to be driving. If you want to floor it and shift at redline a aftermarket cam is definitely the prescription. If you're looking to remain shifting (as you must be used to shifting early w/ a NPI car) at 5000-5200 then stick with a PI cam. Peak to peak (meaning where both sets of cams make their most power) i'd bet the gain from a 268H over a PI cam is only 10rwhp (guestimate), but at 5900/6000rpms where the PI cam isn't at it's peak i'd be willing to be that gain is doubled. Besides the nice little lope at idle, the 268H also looses very little tq below 3200 rpm's like some higher stage cams can.
As for the intake, doesn't that Livernoise kit with the spacers make hood clearence tight requiring a cut in the hood insulation? Either way will work, if you're doing it yourself maybe you'll be more comfortable with the kit. Egh - i didn't want to write all that out, but oh well; it's all in the name of education.
