Sorry, your dynosim5 SUCKS... it's not close to real world power output. Hope you didn't pay for it.
Even the comp cams camquest can suck BIG TIME. I've seen it hit some stuff almost spot on and others be 50-100hp high and not close on peaks.
A 360 built the same as that 318 is LUCKY to make 350hp. Regardless of what some of the fantasy builds in mags tell you... 400hp 340's with stock heads and a XE268H... LMAO... NO!!!!
