[QUOTE="16kOrBust, post: 8125767, member: 132701"] Is it actually a cammed Z06 motor he swapped in or did he just buy LS6 heads and a cam for his stock LS1? There's a big difference because aftermarket LS6 heads are typically ported, etc and perform better than the stock LS6 243 heads that come on a C5 Z06. Same 243 castings but I don't know of anyone who sells stock 243 heads with no work done to them (besides maybe GM). Also, a ported FAST 92/92 intake/throttle body setup for an LSX motor will run you around $1,400 new, so a lot of people do the heads and cam alone first and then upgrade the intake and throttle body down the road when they have the money. My car, for example, has the stock LS6 intake and a ported stock throttle body. I would most likely pickup 20 or more to the wheels with the ported FAST setup but for $1,500 I'd rather upgrade my heads. I have recently seen someone pickup 35rwhp just doing the FAST swap, though, so it's tempting. [/QUOTE]
