I put it on last night, got it all hooked up, fired it, loaded it some...that's about all so far. I will be pulling it tomorrow and maybe into next week depending on how well it goes or who else may need to get on the dyno.

We will see.

after seeing that stout 408 you did Randy with less compression but Chad has less cubes.
uneducated guess by myself
546 ft/lbs
675 hp @ 6500 rpm
nice build Chad,best of luck on the dyno :D

1.44-1.47ft/lbs per cube very impressive
as far as peak hp goes not sure where the engine rpm peak would be with that compression and cam.
going to be a bad ass bracket engine either way :D
