I think an LS4 swap into a Bonneville would be pretty neat.

I guess a good question to have asked would be how much power does the transmission eat up befor it gets to the ground.

Folks, please, get this back on topic. The discussion isn't about an LSX swap, but an L67 swap.

Typical drive train loss is considered 25%.

That would encompass everything after the flywheel and up to the pavement.

You'll need a good cam/head combo.

Possibly intercooler, Gen V, etc...

here is a list of what i had planned on doing
l67 swap with with hd transmission
ported polished supercharger, lim, and cylinder heads
tog headers
biger tb
high flow cat
electric water pump
drop down to the smallest pulley i can
a good torque converter (which one would yall recomend)
cam (not sure what would be best for what all im doing)
and a properly tuned computer

where do u think i will be hp\torque wise with those mods

good to know somebody else was from georgia in here! anyway my turbo prject is almost finished got a couple more things to work through...........

This is your third warning in 4 days to stay on topic. If you can't stay on topic, don't post.

Kinda vague on the mods, but i'll guess anywhere between 150-400 hp. Seriously, if ya want more specific numbers, ya gotta put more specific mods. Get in touch with Intense, let them know your budget and they'll help ya the most.
