Bowl Ported 906 heads. Doggiest engine ever. Gas pig. No torque. We learned some good lessons because of that cam though, such as: - Have a modern lobe profile cam ground up, or use one an off the shelf comp XE. Small hughes, Bullet/ultradyne/,voodoo, whatever... - Low comp 383's aren't for heavy vehicles. If it were me...I'd pass on the MP

Stock 383HP convertor, stock intake and exhaust system, true 9.5 compression, cam degreed in. I didn't like it, not much performance IMO, I think it would have run better with the stock cam. Sheldon

Not sure of the compression, but I can only imagine with the open chambered heads its not good. I also have no idea if/when the engine has been rebuilt, so I can only assume they are stock slugs. It "looks" like it has been worked on, or at least painted on not too long ago. I can always mill the heads for some compression, but thats about as much as I care to invest into this engine. On a side note, what happened to the MP steel shim head gaskets? Can't seem to find them anywhere, but then I found Summit has them listed for almost $200 dollars. Didn't they used to cost like $20 bucks? I'll sell you mine for half that!(not $20) 4941449-MVC-022S.JPG (53 downloads)

I think the larger of the 2 summit cams is still smaller than the 474 and will work better in your setup. Todd 1969 Ply Roadrunner, 383 4-speed on street tires. 3,830 lbs race weight.
