Everybody thanks for answering my question about the Y blocks and sideoiler. I understand now that the side oiler is called that because it oils the mains and the other fe,s oile's the top and a sideoiler is crossbolted and the other one's isn,t at least I think if I am understanding right. I did not know that about a fe.But I understand the difference now. I know they make the power my friend has a cousin that has a sideoiler that he has in his monster truck, and it is pretty mean,it is beefed up to like 1500 hundred horse power and it really moves the truck when you see it in action.But I understand now to make one into a side oiler you would probably have more money in it than what it is worth to buy one and it would probably be better to bore a old fe that is not a sideoiler,a good bit and get a big crank and bigger pistons some edelbrock heads and have just as much fun.
