5 liter MOPAR

Just spitballing here, but what about a 360 block with a 3" stroke? In essence you would have a Mopar 302 and the larger bore. I don't know how expensive the crank or pistons would be, but it might be worth it to check and see.

AFAIK, no one makes a 3.00 crank for the SBM. It could be made easy enough if you really wanted to have one. It will get expensive not to mention the custom pistons that need to be thought out a good bit before you take a step towards building anything.

It’s just money and lots of it.

Below is the Winberg web page for small MoPars. Most use a Ford 302 main bearing.
