Making power out of the 318

Thank you for the ted talk lol i wish i had the money to build that 318 but your right the 360 mag is where it is at i can pick one up running for $400 and put new rings and bearing's in The bottom end as a somewhat cheap insurance and a good cam etc and make good hp for way less money

I would avoid replacing the rings. It would be good to check a few main bearing but if they're good then leave them. A mistake while doing an at home hone, especially if you're inexperienced, and you're right back to needing machine shop services and possibly pistons. Magnums were efi and rarely have enough internal wear to worry about.

Get the mag, get an intake (Magnum airgap), get headers, and then figure out a cam. Keep the old cam and lifters and stuff from the Magnum for the future since they're rollers, but finding a mild roller cam isn't the easiest unless maybe you have one ground but I've no experience with Magnum cams, others might chime in.

Save the ring and bearing money for a transmission rebuild kit since you're much more likely to need to do that than put rings in a Magnum.
