New 2018 UMP mod rules, you can run an all aluminum 577 cu.in. Chevy crate engine.Roller cam and computer controlled ignition. I know what the rule book says. But the way that UMP enforces rules, think about the possibilities!

Still saved me some money though. Probably the cheapest high hp build we have done.

good luck getting it to live. it may make the power, but it will starve itself of oil, unless you have an external rear mount oil pump, and a 4 leaf clover under intake

They don't have a oil starvation issue. Most people who had problems had improper oil in them. You cant run the conventional oil weights in them. Have to be super thin oil. My family has offshore racing boats that use the LS engine. They run at max rpm for extended lengths of time. Never any oil starvation issues.

Brian, would you care to divulge how you came up with 440 cu. in. with an ls-3 block without spending a ton of money?

I said nothing about not spending money, I said cheapest high hp build. It wasn’t $40k
