choosing new setup?pls help!
everything else gm)Raptor cam, dual springs titanium retainers, and harden pushrods.
Bolt ons:
Ls6 manifold, bbk tb, Lt, full exhaust no cats, lid, and no emissions think thats it.
Tranny is built and stalled to 3600
Im leaving suspension out, bc I've got a setup in mind.
The problem I have with this setup is1 of the retainers and spring gave. And haven't taken a head off yet u so not sure if pistons cracked. So pretty much I'm trying to build a very reliable fast setup. Should I get a 408, 418, etc or do I stay with the ls6 setup and do some interal work and a blower? If I were to go with a diff block it'd be built to put down 500 rwhp n/a and eventually blow or spray it. Any input would be highly appreciated.
