You Did - so if thats max with stock crank - then i guess im thinkin thats a tad light .

This will be a numbers block , so no chinese rods/pistons
But The chinese crank might be ok .
Its too bad you lose stock pickup with 512 stroker - or NOt ?


With the 2.20 rods, you can still use the stock pickup with the 4.25 crank with no grinding in a 440. Not sure about 400. Get past the Chinese issue. Most are made there but you just need to make sure the quality is good. I suggest Molnar.
