Is the 337 a 4500 carb intake, or 4150? Any idea how much lower the 337 is than a super Victor? How much hood clearance would be gained with the 337 v the sv, and is the performance level similar?
The 337 is a 4150 flange and it is a lot lower than a Super Victor. There are some old threads on here that cover the intake. I did a lot of dyno testing on that intake a few years back. The 337 has MW ports and a built in valley cover so it is the only single 4bbl intake that fits original MW heads on a RB block.
Here is an engine article I wrote that covers the 337 v. SV testing:
