don't know. I need to play around with engine analyzer pro some more and maybe measure the 0.050 duration on the intakes.

Surprisingly, it appears as though there's not a whole lot to gain after you pass 266 duration (seat-seat). I looked it up and the exhausts are 244. I have a set of VIN 9 cams which have the 266 degree intake's, which I was thinking about swapping the exhausts out with.

I need to measure the 0.050 to make an informed decision...

somebody's doin cams, and i'd like to know...for when it's paid off...i thought any cam change wasn't advisable for a street going northstar...and especially not for the 275hp version since my rev limiter is set at 6k...

a 3000+ rpm stall converter basically lets you skip over the "low end". Stock, the ONLY time you're below 3000 rpm is when you're slower than 20mph.

So, yes you'll lose torque down low, and gain it up high. But, when you gain it up high, you can take advantage of gearing (because it's more HP). New springs will let you rev to 7500. Extend the torque curve from 300 @4000 to 300@6000 and you're now making 340hp. 7000rpm and you're now making 400hp.

You're not gaining torque, just moving it around, and look how much it changes your power!

true, and this much i knew...but seeings as these things either had...what...3.11 or 3.71 gears and i have an H rated car which is govered at 112mph and the motors rev limit is 6,000rpm...now the only real way to take true advantage of that is with an aftermarket engine management and bein a different chassis without the extra crap it would mess with in these cars. changing cams in a true production model...i dunno if it would truly be worth it. you'd need gearing but none are available...you'd have to rev but the stock ecm won't let you.....

Well, I decided to pass on them... Somebody got a good deal though, $150 for one, $103 for the other set.

I figured I'd rather talk to someone about my project first, so I know I get what I want rather than something "just because it's cheap". Even if I do have to pay a few hundred more...
