I was thinking of a way to compare. My last Tunnel Wedge, pump gas, ported heads. At 3500 was 500 ft lbs and climbing
Knowing figures don't lie, but liars can figure, we can play with some math
- Say I was at 475 ft lbs at 3000 = .97 per cid, sounds low but way off peak and it was a TW, not known for low end
- A 433 there would be 420 ft lbs, but built with a dual plane and the right cam for the smaller displacement, likely would drive it up 15-20 ft lbs (low WAG), for 435-440 ft lbs and climbing quickly as it accelerated toward the peak
If the car was geared for it, it will be a blast, if it's a close ratio 3.50 gear, ehhhhh. I drove my Mustang for a few years with Portosonic, 08 LSA 300/250@.050 solid, 433 inches, 3.70 gear and a close ratio, even had a 3.00 gear in it for a run from Vegas to Huntington Beach, and it did fine, the 3.00 gear was a little miserable in town, but had no issues out of traffic.
That being said, a stroker with a 4.11 and a 2.87 gear is way better, but the tranny and gears would have been way better with the 433 too
I will say this though, and have said it before, fast guys make power with heads. You can likely hit your goals, but have to trade somewhere if you do it with cam
