Yeah, but don't over-carb. They way those cars are geared,
the motor simply doesn't pump enough CFM to make them work.

At 1600rpm a 232 is pumping 91 CFM max.

At 3000rpm a 232 is pumping 171 CFM max.

That's assuming 85% VE. It's VERY easy to over-carb.

SUPER COOL! But you'd want tiny, tiny carbs! Motorcycle
carbs! Clifford says "6=8" but for this product on a street car,
I'd say "cool>performance".

A manual trans, even a T14 three speed, would make the car a
lot more "crisp" and tight. The 232 has flat torque literally
designed to work with such broad gear spreads, and T14's are
cheap as dirt.

Seriously, if you hop your 140hp six up to even 175, it'll
drive like a small v8! but it won't stress your nice, cheap,
easy and EXISTING! six driveline parts.


You could buy and ship used T14, flywheel, new clutch and
pressure plate, and clutch linkage, for less money than
rebuilding a Borg Warner automatic. I have no beef with those;
they're fine, and I just had one rebuilt ($1200).

But if you ahve one laying around... :-)

Unlike the V8, you can simply bolt on/off manual/auto trans
without re-balancing motor guts.

Brake upgrade -- always good! Discs or 10" drums (I'm on a drum fad
right now :-)

Unless you go near/over 200hp or whatever, the six axle should
be fine.  For a hopped up stock six there's no need, and the
V8 axle weighs 75 lbs more (the Gremlin already has a poor
sprung/unspring weight problem back there! -- talk about wheel
hop on corners), are harder to find, needs a new driveshaft,
etc etc... why bother?
