Tunnel ram 440

Sorry I wasn't thinking about the pistons he was using. I was talking about older 440. Don't know what I was thinking.

In 67' Mopar came out with the one year only 915 closed chamber head. An old racer trick was to install the 915's on there stock 68-70 440's of course this was before they had all these Hi-Po aftermarket part. It would up their CR a point. Read this in an OLD Mopar mag,so I figured with the thin head gasket it would be close to 1 1/2.

I think the Hughes Whiplash cams are for Magnum engines that are converted over to carbaration.
