I have always heard of them, But now I have one. I purchased a 440 from a boat and during assembly I found out it had a spun balancer. The timing mark was at approx. 2 o'clock position at TDC. Is this really rare or just my luck?
Doesn't some boat motors run in the opposite direction to car engines?
It's not. It just goes in the opposite direction
I am using an aftermarket timing tab, all the front of the motor had was a timing chain cover with no tab. Using an aftermarket aluminum pump housing. I was told that the starter was mounted in from the back on the pass side for a reverse, must be urban legend, could not find anything to back it up. I was given a starter, I do not know if it is from a boat or not. I will hit it with 12v in the am.
Thanks, Been looking all over the web for info and the only real thing I can find is the cam has 2 gear drive to make the cam run opposite the crank. It came with a normal oem chain and gear set installed which looked original with oem penstar. The oil pump camshaft gear meshed fine with a new lunati cam, but it did have that thrust bearing under the distributor. That is what is throwing me off. I cannot find anything that makes me believe it is a reverse rotation engine. The dampener is also a head scratcher. The starter goes in from the front of the block on drivers side like normal. I really just do not know.
Reversed rotation engines were mainly used when there are 2 engines side by side in a boat. One of them would be running reversed.
