Victor, Super Victor...or just stick with my LD 340 maniflold

The cam is large enough, but yet still what I call, boarder line-ish, in size, (if not slightly under that line I have in my head) that the intake choice can be ether intake manifold style. The dual plane will offer more torque down low while the single plane offers better top end rpm power in the typical like fashion we basically know of. It just all comes down to what your doing and the goal.

Since you have a new converter with a higher stall in what I am assuming is more of a race car, you are ignoring the low rpm power to get into the meat of the power at a higher rpm. This is for sure going to help the car.

(I don’t know the cars gear ratio or tire size, but I’ll assume it is more so for the strip.)

The only draw back right now is the overall weight of the car which makes me a little nervous on how well the actual gain might be. I’m really more with @scampy. It may be close to a wash.

Looking forward to the slip report.

Ignore the RPM thing.
It's hard to ignore rpm when every manifold description tells you what rpm it work best in.
