The Dark Side: V8, V6 & 4 Cylinder Engine Conversions and related radical modifications (brakes, transmission, suspension, drivetrain) for MGB, MGA, Midget and all other MG models. Purists beware!
I currently have a Carter AFB 400 carb on a stock Buick 215 intake manifold. Would this (Ebay) intake be preferrable.

Thanks, Brian
A hair taller, but breathes a lot better than the stock unit. The runners and ports are bigger, so if you have Rover heads, it'll be a better match. Good stuff! I believe its generally considered the best aftermarket intake for conversions.

I hope to use the MGC hood myself. Think they have a great look with the flared fenders. Not sure on the adapter plate.
Looks like there's going to be a bidding war. Is anyone here bidding against me I, don't want to run this up.
THere's always going to be someone bidding against you - its an auction! Almost the whole world is on the internet.
Spoke with D&D, and they recommend the OFFY intake with the Performer Carb, does require adapter plate, not sure that the Holly plate would work, doubtful. Already got a decent carb, so I'll take a shot at the intake and see what happens. D&D says the OFFY height increase is .020 over the stock Buick 215 intake.
An MGC hood should clear the Performer intake and carb. With the scoop I put on my car, which only sits an inch or so above the hood line, the only thing above the hood is the hold-down nut for the air cleaner. This is using stock RB mounts and a 1.5" drop-base filter assembly, K&N filter with "Extreme" top (which is a bit taller as well).
Brian, FYI there are 2 different types of Offenhauser manifolds, the Dual Port (Part #7001), and the older single plane 360 degree Equa Flow (Part #5165). I have read that the newer Dual Port is the same height as the stock manifold and the Equa Flow is about 1/2 in taller than stock.
They also have pretty different port configurations, with the Dual Port having the equivalent of two separate intake runners in each port.
