Serious 340 build into 361 HiRPM Screamer

All I'm saying is that I know PLENTY of people that take their 340s to 7,500 and all the up to 9,200 rpm reliably making power up there too

Oh, well I don't know anyone that does that around here-whether its a 350 Chev , 302 Ford or 340. Even our circle track stuff is NorthEAST DIRT Mods are limited to 7600RPM and they are all done by 6700-6800 rpm and lose about 75 HP when spun all the way to the limiter. J.Rob
