Sorry, I aways assume people know what I have. 1500 and yeah, I need to get the speedy sleeve. Mine is POURING oil out. ( well, not pouring, but the entire underside of the car is wet.) I have been driving it at 70 MPH or so and it always seems to leak worse. I need to plumb a PVC valve in it, but I've been lazy. It's easier to just add oil. I'll wait till the summer and pull the engine. If I gotta pull the cover, might as well do everything else I want to. I have a chain and tensioner here, cam gear too. Need to get the crank gear though. Gonna rebuild it and go 9-1. I'd like to go higher. Does anyone else make 10-1 pistons that are reasonable?
