Thread: furthest under for crank/rods on a blown motor; 10/10 10/20 20/10???

As far as rod sizes---they can be ground down to standard chevy sizes, either bbc or sbc(Nascar now uses Honda size)
Mains---mostly bearing choices--severe undersizes don't have top level bearing materials
Hardness of crank needn't be worryed about---the steel crank is harder than most cast cranks anyway
Whats wrong with the crank you have????if you have one---

Depending on budjet there are lots of choices

In one that I'm building for myself ( 33 roadster) I am going to offset grind the rod journals down to 2.2 bbc size and run billet rods on it

The smaller rod diameter lessens the clearance grinding necessary in the bottom of the block also

PS----I'm looking for a mag Cragar blower manifold and an Enderle barndoor injector so I can build it like the engines from my dragracing days( and nights)

Thanks Jerry, I talked to PAW again this morning & the block they have is already bored .060 over & the cylenders aren't in good shape so they were going to sleve it back to standard bore. The best crank/rods that they had were 20/30 under & my engine builder said don't get it.... So back to square one....... Bill
