588″ motor in my 68 cuda…

I am having Todd at Marsh Performance build my motor for me. after reading about the motor he built for moparts member Tig, I knew I wanted him to build mine. It specs:

588 ci
indy aluminum block
indy 572-13 heads 410-420 cfm
diamond gas port pistons 4.5" bore 13.5-1 cr
callies 4.625 crank
cam motion solid roller 282/290@.050 .800/.751
indy 3x intake
1150 dominator
isky xmax bushed lifters
jesel 1.7 rocker arms
oliver rods 7.100"


this is going in my 68 formula S fastback cuda. it is a 4 speed car, with a 3.73 moser dana 60. it also has a hemi denny front coil over front end.im hoping for about 3200 pounds. this is a street car only.

anybody want to guess the hp and tq for motor? I'm hoping for 900hp and 800 tq. Todd will dyno it, so I will know what it makes, and will post the results. I should have it very soon!
