Vortec/carb guys...

What kind of power are you guys making? I have my L98 that I have to go .030 on. I'm picking up some Vortecs and going back to a carb'd setup. I'm not sure on a cam. But what kind of power can I expect from a mildy cam'd Vortec head'd 355?

thanks

uhh, nice sig pic, stellar mspaint job right there, hahaa

You can do 350hp (1hp per cube) with a reasonable sized cam. That's a winning combo right there.

Big fun comes when you either go to a bigger cam, and/or put the 3.75" stroke crank in it. Now that's where the 375-400HP motors are being made.

thanks! I majored in MSPaint at a Community College.

This motor is going to be mated to a 700 with a 2400 stall and shift kit. Full exhaust ofcourse and a 3.42 rear posi. With some sticky sticky drag radials do you think low 13's are possible?

Yes.
Don't go too big on the cam then with that wee stall speed.

The stall speed is your biggest limiting factor for cam size.
