Re: [Amc-list] intake ports, was exhaust tuning

[Frank Swygert <farna@xxxxxxx>]

Well, you're correct -- sort of a two into one deal. I was just going from memory, and know there are four ports easily visible from the "trough". They split far enough down that I was thinking cutting down enough to separate them and have enough sealing area would hit a water jacket. If you ever run across a cracked had and have some spare time maybe you could mount it on your vertical mill and find out.... ;> 

Hey, Howell on the 196, Jeep 4.0L setup on the 232....  You do know the intake will bolt on with minor mods, right? The exhaust should work too, just may have to cut that flange off. Better yet, locate an 81+ exhaust manifold...

It's hard to describe, but the I I ports aren't *quite* siamesed; the 
port walls come to a triangular point (at least on this head). It's moot 
though. Even if you sawed and milled off the trough (SHUDDER) you'd end 
up with at best a 1/8" - 1/4" flat between adjacent intakes.

EFI would solve it all.

But not thinking about that now, on this car, at this time. First, the 
Howell on the Classic...
