360 stock intake manifold on a stock 318?

I think the factory 318 with 4 barrel came with 360 heads? and the old Edelbrock 318 Streetmaster aluminum 4 barrel intake worked great and had the small ports

At least the E48 motors did- the common cop car/towing/HP motor.

It's really too bad that "Ma" didn't make these engines more easily interchangeable, AKA 360 heads on a teen.

Yes there's a compression drop going to 360 heads on a 318. It drops down near where the compression of those 360s was. Outside of a handful most 360s were dismal low compression right down to where most people try to keep 318s away from. That's why Chrysler put 360 heads on them and called those 360 heads an improvement over the 302s. Don't think the E48s had just the 360-LD cam though.

What's a shame is that they didn't standardize more into the 318 line following the introduction of better parts on the 340 and 360 lines.

A less dramatic but still viable improvement that will piss off the average looser on the street is the 360 2bbl swap. It looks stock but flows better and great bottom end. You'd be surprised how much power a 318 can make with 300 CFM.... :tongue9:

Course, you go through as much work since the intake's different along with the carb unless you put an adapter on it. But yeah, the comment was exact for a reason- I don't think it's very much too insufficient, but insufficient at all is enough to be a negative.
