Quote: Thanks for the information Andy. I know a few people that have better heads then the Indy EZ heads on stock blocks. I am going to point out this post to them and hopefully enlighten them on the possibility that they are driving time bombs.
Yep, I agree. Anything cylinder head that is capable of making more power than the EZ head really deserves an aftermarket block.
I'm going to be interested to see if there is any power difference between what my cracked 505 was making and what the new 514 will make. The 514 will have the same exact heads, cam, intake, carb, etc that I was running on the 505 so the main difference will be the block itself and small changes to the bore and stroke.
