now, these are the exhaust lobes for 8 and 7? did they do 4-7 swap on reverse rotation engines? because this is 8 and 7 right next to each other. my old small block cam has them all but 180 degrees apart.

last half of firing order sez 6348. Is CW standard or reverse rotation? This valve cover says cw.

It looks might of got some water in the cylinders and hydrolocked and broke the rods.

After some research, looks like CCW is standard rotation. So this is definitely the opposite rotation engine. Now, are the oil drilling in the crankshaft the same? And do the Pistons have to go in the other way for any reason either the offset on the rod or the oil spurt whole or anything like that? Or can you just spin a standard motor backwards with the backwards camshaft?

If this a reverse rotation motor with a gear to gear timing set, you need a standard rotation camshaft. The camshaft need to turn standard rotation for the oil pump to operate in the correct rotation.

That thing got HOT...................oil starved ??

Your going to have to read from th beginning. Kind of a roller coaster ride.

actually, it's a reverse rotation camshaft. It just happens to turn standard Direction, opposite of the crankshaft rotation. The main difference is the opposite firing order.

I am so glad I have bravos. He has transmissions right. Can one be reversed. Then both engines coulbe standard. Life would be easier. Dont know much about the transmissions
