That was pretty close to what you was shooting for, wasn't it? I still haven't hit the rollers on the 370 I have. still try'n to fine tune.

Yep I wanted 400hp from the build
Curious to what yours does.

yeah, I am too!!. I'm replacing the 28 with a 34 radiator and doing 07 efans. I'm waiting on the harness to arrive. I'm also doing some newer coils and plugs and wires. I hope in the next week to hit the rollers just to see how much she makes. tune is a little off so I hope to brush it up first..

Nice number. Bet she runs good.

That's pretty dang good. Congrats.

Power is right where it should be. Nice job!

My 6.0 is jst like your 370, but it has ported 243's and 10.7:1 compression, so after seeing your results, i'd say it's safe to say i'm sitting right around 400rwhp also. Good to know!

Pump gas?

93 octane pump gas

400/400, nice flat torque. Love it.
