My original intention was to do the same for my 65- basically make a 3" main 421. cost for a 4.25' is the same if not cheaper.

if cast works go up to a 4.25" stroke. That is what I ended up doing for my 389, but I was buying pistons already. Dished 389 pistons are not a cheap hobby...

Butler has cast eagle in that stroke for what I thought was relatively affordable. Spotts is building my engine he said they are good to 6k rpm.
