What kind of RWHP are you making? Stock or modded

Maybe a route I would go down the road. LSX seems pricey

Building up something substantially more powerful now though still LT1

Re: LT1 people

bolts ons was 288rwhp 290rwtq..

Old LE2 setup was 374 rwhp 360 rwtq through edelbrock shorties and stock block.

New LE2 setup with the addition of a ported intake, lighter rotating assy., more compression, zero deck, and new LE2 cam with supporting valvetrain is 405 rwhp with 390 rwtq on old tune, waiting to tweak it in the early summer.

There is a 385ci LTx on camaroz28.com making 466 rwhp and 449rwtq now also..

Re: LT1 people

LE 1 , 1.5, 2, and 3 are stages of custom cams and heads cams done by lloyd elliot at www.eportworks.com

He is one of the better performance deals out there.

Sorry I assumed (wrongly) that the packages were more common knowledge.

also check out the LT1 tech forum at www.camaroz28.com/forums
