Mind sharing some specifics about the heads combo on those? I know they are eldelbrock BBO heads, but are they milled, what springs & rocker setup, ect.

Thanks!

It looks awesome!

I had a shop order and build the motor. Its bored .030 over full roller. Rockers arms are 455 7/16 1.52. All Comp Cams pushrod and rocker arm kit as far as I know.

Weird, factory ratio is 1.6, wonder what those rockers are for sbc?

I dont know I know nothing about how to build a motor. Out of my league for now.

As long as the pattern is good and pushrod length is right, they should work fine. You will have less lift than advertised as Olds cams assume a 1.6 ratio.

Ok I see. Do you think I would notice a difference? More lift seems better but IDK 🤷🏿‍♂️

I was just going through this thread but haven't found the cam specs, what are they? Your heads move serious air, around 260 CFM and 190 exhaust with a much better chamber design. I say 1.7 rocker arms but it depends on the cam, those heads will take .575" lift.

What does the cam call for?

 

[olds307 and 403]

Found it. Your intake lift will now be .504 and exhaust will be .489. With 1.7 ratio, .564 and .547.

Rocker Arm Lift Change with Ratio Variations
