I like a girdle on a 302....because the block is really weak and the girdle will keep the crankshaft from ruining your tires.

And I sell a lot of them for the 351W. But...at 530 horsepower you are well withing the capabilities of the stock block.

I don't mind the add on 4 bolts......if you have a very, very good machinist.
