and with 588's you will make in the neighborhood of 900ish hp and be safe it the charge air department...

hey mild thunder a chiller does two things to air, its cools it, thus condensing it (shrink) and as a result, lowers boost, also intercoolers tend to be restrictive in nature as the air has to pass thru the core... that being said, lets not miss the true point here, the benifit of the chiller is that it allows you to run the blower much faster without the risk of detonation, this equals higher torque and horsepower (net)

If they were 500's then you'll need way better cranks and most definatily better rods + pistons also.
Because most aluminum heads will lift off the decks on 502's at that cylinder pressure....800-850hp.

head studs will help as well as a good gasket, but ultimately you would need a good block, with the right rotating assembly... bowtie race block, or merlin...

Okay so forged eagle cranks, forged je pistons, and forged gm rods are not going to make it to the 800-850 range? I do plan on running the iron heads, and the motor is built with arp bolts now, and real good head gaskets. I realize those will have to be new when we do some more work on the heads before the blowers go on. What hp level can my bottoms ends live at? I thought I had read lot's of story's of people strapping some big stuffers on there 500's and having them live at the 800 mark? (the only stock part in my bottom ends are the rod's themselve's)

Will be twisted into pretzels under that kind of torque.

But I like the way you are thinking.....New Power and drives.

Hey Jason, being patient is not best quality, but I actually am buidling the rest of the boat to handle the new power before I tear a bunch of stuff up. Big shaft #4's already hanging off of the back, and huber 1350 transmissons as well.

Alan I appreciate the offer, I actually grew up in southern Ontario. The 905 area code looks familiar:) I have a very busy week but will give you a shout next week for sure.
