Mild 318 misses at 3000rpm

That's where it's a guessing game. This motor was built by a third party and was sold to me when the car it was built for was sold and that buyer wanted a big block. The pistons are some version of the hypereutectic KBs but I don't know for sure which. I got the whole thing carb to pan for a song.

Cool on the price! Then please take a complete set of cranking compression readings and let us know. I was just worried that they snuck some domed KB 318 pistons in there and then your DCR would be up in the high 8's with that small cam and then you'd very, very, very probably be facing detonation issues.

Just checking all the bases....and it would be good for you to know more about what you have.
