my friend just traded his truckfor a 98 camaro. the kid he got it from was, not the brightest. he claimed it was a lq9 with a ls7 crank, shaved and p&p heads, blah blah blah. i get over to his house and explain the kid was full of poopoo. so after checking it out, it has what a appears to be a lq4 with 317 heads. the heads have been off before it seems, because i see arp head bolts. mild cam also.

the engine has a vibration, can feel it much driving, but in park you can, and the more RPMS, the more noticable it is. im wondering if the wrong flywheel was used? Do LS1s come with a wieghted flywheel? I noticed on my lq4 on the stand, it has a non wieghted flywheel. If that idea is rubbish, what else can it be?
