Just wondering. And if it is standard flow has anyone converted to a reverse flow system. You know, when the heads get the cooling before the block.

GM switched back to standard flow with LS1, they felt it didnt acheive the results they were looking for. I dont have the answer your looking for about your second question, but if your interest is in lessening detonation you could try a 18 psi rad cap instead of stock 15psi. <img src="gr_stretch.gif" border="0">

LS1derfull - Excuse my ignorance, but how would a higher psi radiator cap help detonation? I really am curious about that. <img src="gr_stretch.gif" border="0">

Ok, higher pressure in system purges steam pockets more effectively and raises boiling point of coolant somewhat. Stagnant areas in cylinder head coolant passages promote detonation, from forming hot spots for comb. chamber.The 18 psi will help to deter stagnant areas and boiling of coolant in localized hot spots. Does that help?

Wow, I had no idea. Makes a lot of sense though. Would you suggest that be an easy 'mod' most should be running or only in extreme conditions, aka heads/cam/blower/spray? <img src="images/icons/confused.gif" border="0">

Thanks again for the info. <img src="gr_stretch.gif" border="0">

I reccomend it but i must mention this is also harder on head gasket sealing of coolant. It shouldnt be a problem but it would show up sooner if there was. I say do it GM makes these kind of changes with out problems.
