I did do many test fits with the intake and kinda have a procedure due to the many times I have taken my manifold off my drag race motor. I do have a few different valve spring removers so that is not an issue.

I am running a Victor Jr. with an 850 for now due to the altitude. If I take it down to sea level at the Delta or something I have a dominator I want to try out.

Good looking build , have one similar but went with a bow tie block so besides the cam nose had to chase down a imco timing cover , that was more than 8 yrs. ago . Old thing still fires off and runs all day , good cheap power

What size domes on the pistons ? Is this to be raw water cooled?

I believe they are -10CC and will be raw water cooled

Finally got the motor off the stand and all parts off and on needed for the dyno this week. Anyone have any guesstimates on the HP? I am hoping for over 600 and close to 650.

Retainers do look scary. Hope all goes well on the dyno.

never mind

i have a number in my head but i will wait for the dyno results.i think the gm heads might hurt you.

I'll take a crack at it. 620 @ 6,350
HR.correct installed 2 deg advanced.

I think your heads will be your holding you back some but can always strap some one down the road.


Dyno headers?

I wonder what has been done to those heads , did you go with 2.250 intakes? The exhaust side is where mine gave up on flow.

600 at 6000
