I recently picked up a 1984 vintage 454 from a motorhome with only 60K miles on it. Pulled the heads and the bore look good but a little surface rust from sitting!! I still see a little crosshatch on the cylinder walls. I may yank the crank and pistons and give it a quick ball honing and put new bearings and rings in....

Anyway...the heads on these are those wonderful tiny peanut port ones..They are now under the workbench!

I picked up a set of PROCOMP (I know..but the price was right!) Aluminum heads PC3021-396 Closed Chamber oval port heads to use.

I also got another screaming deal on a complete COMP CAMS Mutha Thumper ROLLER cam kit cam #11-601-8

I also plan on running a tunnel ram on this motor as well.

This will be in a 2800lb sedan.

Comp cams says the cam works best with 9:1 compression...I'm pretty sure this motor was 7.8 or 8.1:1 from the factory. By using the closed chamber heads I'm sure compression will go up a tad...Think this combo will work decent?? Should I just go for some compression with new pistons while its apart?? The car is just in a Saturday night cruiser. Thanks!
