72 340 actual hp?

Jerry says his is 350HP with headers not sure of the carb set up. The 1969 motor manual I have rates the 68 & 69 at 275 with the 4 barrel. I can see 350HP with cam headers and 650CFM-750CFM induction. A friend of mine in Reno asked me one day why his 340 Cuda would not light up the tires and I said let me see the engine. He opened the hood, and I said Hooker Headers in Ontario Cal. will get your tires spinning. The next time I seen him he had them on it and it was spinning the tires with ease. That is a known fact, that MoPar had the siphoning restricted exhaust systems, the 340's being the better of all, but still headers open any small block MoPar up to it's real potential. So A 6 Pack set up with headers is like 1050CFM opened up it would be like a 440 with stock exhaust 375 + HP. The rating for the 72 is 240HP in stock form with a 4 barrel maybe 575CFM-625CFM, with little effort like said here it can get to 300HP easy and thats with 8.5-9.1 compression, cam induction & headers.
