I'm partial to the 6 speed. It's all I've ever owned or driven in a LSx. They are lots of fun and are strong in stock form, but can be built to be virtually bulletproof.

Autos are for pussies. Get whichever built T56 you'll need based on your power level. Check out some videos on youtube of the fastest 6 speed LSx on the planet. It's a blue 4th gen Camaro. Dude bangs the gears in a 1300 rwhp monster and runs mid 8's. He runs a RPM transmission.

Call Richard at WEST COAST RACING HEADS very smart guy he hooked me up with this set OF 12-1 for my LME 427

With the all pro 12-1 heads a aftermarket shaft rocker is required on the 12-1 head due to the fact the the rocker bolt holes are bigger that stock.These were designed for high hp application . The all pro ls7 retro head you can use stock style rockers.
