Yea larger valves but doesnt show flow numbers, still alot of variables for dyno numbers as they all read different.
Tires and wheels, gear ratio, tune, fuel quality all play into power numbers

I also say around 380-400 Edit: Closer to 400. Seems like lately a lot of cars are dynoing higher with mild cams than they used to with a T rex or MS3.

I've seen plenty with equal mods and a FAST intake come in at 400-420 so it's hard to see yours be higher than 420.

Most will agree that the “magic” here will be in the tune. Lots of power to be found there. I usually don’t bite at these type of things, but I’m gonna step up and say 407/380. I bet it’s gonna be a blast to drive, no matter what the stupid dyno says, and that’s all that really matters.

No idea really due to the two wild cards tuning & what type of dyno.

M6, forged 347, 11.1 to 1 compression
mild ported 243s - Perf. VJ & cleaned up runners
BTR stage 3 cam - 231/242 .617"/.592" 112+2

​​​​85mm TB, LS6 intake, fast 36lb injectors,
1 3/4 longtubes with off road x-pipe

428 whp & 392 Dyno-Jet

Man, another suck the wind out of my sails thread. I am building a combo very similar to Aarons. Only TSP stage 2.5 CNC 243s and BTR 2 NA cam.

I know I know dynos are just a number and it's all in the tune and how it drives. Thankfully I have one of the best tuners on the west coast.

My car will be on the rollers on the 25th.
