Specifications:
I have a 78 Z28, with small block 350 with an RV cam, will this work on the Th350 transmission with the Transgo reprogramming Kit?
Will this kit work for a 2006 6.0ls with the th400?
Why does the kit specify small or big block application but if you follow the link for the torque converter included - it says “recommended for small block only” in the description? I’ll be using this on a gen 4 427 BBC with a TH400 & 4.11 gears.
Is this the best converter (kit) for a 1967 Camaro RS 3:08 Non-posi rear with a BluePrint 3550CT/CTC Engine. Recommended from engine manufacturer is 1800-2200 stall. Would I be better off with something lower than the 2000-2300?
Will this allow me to mate a 5.3 to a 400 turbo without any adapter
I have a 64 283 and my flex plate is different from stall converter. Do you have that combo
Will this fit a 05 Chevy 2500hd 6.0 vortec with the 4l80e transmission?
Will this fit on a 95 GMC k1500 5.7L
