New guy with M300 mini motorhome.

Yes, access is pretty good on the sides and top , The fronts not so good.

Does anyone know if they made a 4 barrel intake for the 318-3?

Here is a simple 4 barrel adapter that works quite well with the stock 2 barrel manifold.

Have used them multiple times with great results.

Don't have to pull intakes or change cams, works fine with the stock cam stock engine.

'69 318 with 4 bbl adapter. Nice improvement on performance.

Summit and Advanceautoparts handle them, like $20 bucks.
