I'm building a '95 351 to replace the one in the boat ('93). The current one is a solid lift cam (I presume), the new one will be a roller motor. I just picked up a set of GT40 heads off an Exploder (I did not expect them to already have 1/2" head bolts!?!), as the current motor has GT40 heads. I want a one day swap of long blocks, if I can.
The boat runs great cold, but at 850 hours, it smokes a bunch after it's warmed up, and always surges at idle (after warm). I admit that i need to do leak down & compression tests.
The block I got had some damage done the pistons from a dropped valve, so I cannot reuse the original dish pistons, and I will have to order new.
I want to keep the compression low enough to run regular gas without detonation. My bronco has the dish pistoned 351 with small chamber aluminum heads on it & runs like crap without '93. Hoping to avoid that.
What's the best low budget piston, for a motor that will never see more than 4500 rpm, usually no more than 2500 sustained?
Thanks in advance.
