Alright, I'm looking to build a 10 sec car. And time to get the t a back in commission. Anyway, I currently have a gm ls6 crate engine internal modseverything else gm)
Raptor cam, dual springs titanium retainers, and harden pushrods.
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.What would be a very reliable 10 sec daily driven setup?I want to no pistons rods crank heads cam etc. Any input would be highly appreciated.
And will the 4l60e tranny still bolt to the ls3 blocks,

I have and recomend an iron block 408. You will need to turn some high rpms and be able to breathe really good....I'm running a 255/263 .624/.624 115lsa cam, 12.5:1 compression (8.22:1dcr) ported/milled (56cc) 241's and a ported Edelbrock proflo xt intake with fully forged bottom end and H beam rods....built to handle 300+ shot on top of the motor.
I daily dtove this 50+ miles a day with a 4,000 stall and built 4l60e (grenaded 3 built trannies) now going to a 3 speed manual
