Aloha gang,
Well, i got this job done in 4 days. Took the heads in for a rebuild and installed a lunati gold valvetrain. I also installed ls7 lifters, ls2 chain, ls6 ported oil pump, arp head bolts, asp underdriven pulley. The whole kit was only $1600 bucks. Great deal. Specs are 235/240 duration 630 lift on an 113 LSA.

Thanks.. Wasnt really that hard. Just had to be super carefully prepping the block for the arp head bolts. Tuning out here is not the best, and theres a long waiting list, so im sending my pcm back and forth to texas getting my tune correct. Then i'll post a dyno sheet. These cams make good power and nice torque curve, thats why i chose englandgreen.. Mayhem 2

Thanks........
It will sound a little more crisp and steady when I get it tuned. Sat the tune will be done. Im using obx Shorty headers, the stock cats and borla straight pipes over the axel. The Shorty headers didnt add any sound at all. I'll probably end up going with LG longtubes and a fast 102 intake next round of mods. I really want a harrop intake like in this pic below. I'm going to try to score one

Did you need flycuts for the pistons?

Nope, no need. Turns out my injectors are to small though. Couldnt Max out my tune. Couldn't raise timing over 22* couldn't go over 6100rpms. So with 398rwhp there's more to be had when i install my new injectors. Maybe 40 more rwhp. Think I'll port the tbody and ls6 manifold too

Yeah, heads will be pretty soon. Turns out my injectors were holding me back too. Could raise the timing up where we wanted, and at 5800 duty cycles were95 already. And this came redline Is 6900. So I'll port the tbody and get some new injectors and retune. Then the end of summer I'll get a set of heads. The cam is a comp cam actually, but England green sells it in a killer deluxe kit. Now the cars tuned my idle sounds even bette. Set at 825rpm
