It's an AWSOME intake, for low RPM efficiency, part throttle torque, and throttle response. (Commuter or RV/Truck manifold)

DOn't expect any big power at WOT from it, maybe about like a stock dual plane....

Love them, run two, ran LOTS.

Mains need to be richened up more than you would think, if you take the carb off a dual plane, or single plane, and bolt it on the same engine with a dual port, it will be lean.

ya i cant wait to take the car for a drive, i just put the 360 in replaced my stock 273 which only had 90lbs of compression with this stock 1977 dodge rv 360 with 190lb
hopefully it has loads of torq

OH, it'll have alot more of everything over the 273. You'll be happy.

Yeah I'm only getting 12-14 mpg with my 273 right now, I'm hoping that with a few proper upgrades I can bump that number up a little bit.
