Re: [AMC-list] A couple questions.

[Frank Swygert <farna@xxxxxxx>]

I can understand Mark's questions concerning flow. The 327 heads have 
relatively small valves and size can't be increased much due to valve 
and spark plug placement. That's one reason AMC didn't make a larger 
version of the engine, plus it was pretty heavy for its size. The valve 
sizes are fine for a mild 327 though.

Whether there's much increase in flow (or that increase is usable) is 
moot when economics come into play as Russ mentions. A used aluminum 
GEN-2/3 intake can be had relatively cheap compared to a 327 4V 
intake... sometimes. Just depends on what you run across and where! I've 
seen entire worn/locked-up/blown 327s go for pennies with the 4V intake 
and carb on them, but try to buy the intake alone and you run into what 
Russ is discovering! If you can make the adapter plates yourself at 
least you'll lose a few pounds off the front of the car by using an 
aftermarket AL intake vs. the factory iron intake, and maybe save a few 
bucks. If you have to pay a machine shop it's probably not worth the 
effort or money.
