ep240 pump good enough? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have an ACdelco ep240 pump, with only a few miles on it. This was installed as an upgraded TBI pump, but then I changed direction, and am going with a LS motor.

I've gotten conflicting data on whether the ep240 will support a stock(325-ish hp) LS motor long-term. Some folks say the ep240 will easily handle a LS, others say it won't.

Should I pony up the cash, and replace that pump with a ep381? Or would it be a waste of money?
