Re: [Amc-list] 71 Gremlin 232/ Tom's intake

[Wrambler242@xxxxxxxxxxx]

I ported an 81 exhaust for on my 69.
It seemed to work pretty well.
I got some brass pipe plugs and threaded them into the AIR fittings.
Pipe thread is technically wrong for this, but using the brass plugs allows them to go right in!
Then I used a gasket and taper ported the exhaust to take the edges off the exhaust. 
IIRC this worked out pretty well and I got the opening to match fairly close to the big port gasket.
I drove it for a year or two this way and it didn't leak.
I still have this exhaust and intake mounted up on the 232 I pulled from my 69.
Never pulled it off after taking the engine out.
