I'm probably going to dyno it, but I'm curious as to what y'all think this will do...

350 bored .2 over
RPM Air Gap intake
Lunati Voodoo Cam
Advertised Duration : 262°/268°
Duration @ .050 IN/EX : 220°/226°
Gross Valve lift IN/EX .475''/.494''
LSA and ICL 112/108
96+ vortec heads 1.5 ratio rockers
Dynomax Full Length Headers
2.5 Inch dual exhaust
600 cfm edelbrock with vacuum secondaries

No you aren't going to hurt my feelings if your numbers are low...I'm just curious...

It'll be a couple of months before I have enough miles on the motor that I'll feel comfy dyno'ing it.

Anyone have a thunk on it?

.200 over :eek: what are the cubes? :D , I am assuming that you mean .020 over :confused: I'd guess between 3-350 at the flywheel.

Probably about the same as everybody else that builds that motor.... it being a pretty common combo, except with slightly different cams of roughly similar duration and lift.

Should be in the 375-385 HP neighborhood if the exhaust is any good. There's more to exhaust than just pipe size and count, of course. Use a crossover tube, it REALLY makes a difference. Might be as much as 15-20 HP depending on your particular setup.

Thats the same combo I'm putting in our wagon except I using the next size up Voodoo cam (60103) and a 750 carb.

I'm hoping for 400 horsies

Cool...good to know...

I almost went one step up...but I didn't want the start of my power band that high up in rev's...
