Why didn't you post a pic of a good block!

I'm sure everyone has already seen plenty of pictures of blown up Chevy's and Ford's
Another con is you lose some power over a iron block.

It's usually the heads you would find the loss of power in (if any) not so much the block. Even then the difference in power is slim. You are far better off with the weight savings on the heads and block than the cast iron units. And 300lbs (block and heads) off the weight of the boat is a huge difference in weight. That's one fat friend or two skinny ones. Or 3 hot chicks. :rollside:
ive noticed a major loss of power with this damn motor of mine.. guess its not a good idea to put cast iron heads on a aluminum block.. shit guess i got that one backwards.. :cry:

ha ha ha, when you gonna learn
Anyone know of a decent Aluminum Block For sale??
Price expected to pay?
Loss of power with an aluminum block can out weigh any weight advantage in a drag car, but not sure that's so with a boat. Heads have nothing to do with alum. vs. iron block. Simply put, the iron block is much more rigid and will hold it's shape better. Less heat expansion, less flexing, and so on. On a 500 in. Pro Stock motor it can be as much as 50hp. Up side is as already said...repairability being the biggest factor, and the weight.
