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.

A million 9? :D

Not sure where he ended up on total combination but I am guessing more than 600 hp.

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.
