GM Cam opinion

I was looking at a cam in the GMPP Book and this is another Cam I came up with.
#12370845 Lift is I:488 E:509 with 112 lsa.

I want to use this with a 30 over 305 with flat top pistons Vette alum heads, 2200 to 2500 stall converter and 3.73 gears.

Opinions Needed

with a carburetor right?

you will need a bigger stall if you run 3.73 gears, or the converter will do you little good.

No its a TBI motor. How much stall would I need and how much is too much.

the Vigilante 9.5" is a great one with good stall-torque ratio and lockup feature. Anywhere from 2400rpm to 3400rpm is a good range for that converter.
I wouldn't even make a guess with any other brand converters.

The 845 cam? Isnt that like 224/230 duration? If so, thats HUGE for a TBI. Why do you want such a big cam?
