Excellent! That would serve the 421, 428 and de-stroked 455 market.
Lots of 428 and 455 blocks out there.
Better to also have availability of 3.25" main journal, 4" stroke for 428 and 455 blocks. Best is the 3" main journal, 4" stroke for a 389 or 400. But with the eventual growing scarcity of non 557 400 blocks, the 3.25" main journal 4" stroke in a 421, 428 or 455 is a valuable alternative to instead using a 350 block.

I reached out to Molnar and they are willing to do a run of 3.25” main 4.00” stroke cranks as well if anyone is interested. They need a minimum order of 5 to move forward. I’m in for one. They are contacting all the major Pontiac vendors gauge interest. |
