So on to the next question. I have a buyer for the original un ported aluminum MP heads. I think that I should go with the new Edelbrock head designed for larger stroked HEMI engines, (mine is 540cid and will be larger once the bores are round and true).
I hate to go to all this work and expense and not make an improvement!
Combo is 4.375? Bore with 4.5 stroke. 248/254 @ .050, .585” lift net on a solid roller.
I am running a Mopar “Marine” intake with two 750 Hollys.
This is a 4,175lb STREET car with 3.54 gear and Gear Vendor overdrive.
It made peak power (635) at 5,900 rpm with the MP heads.
What do you all think about going to the Edelbrock heads?
