Re: MC conversion questions (4KQ)




Yea, I forgot to mention the hole in the MC Intake.  Round and oval TB's
are not interchangeable.  Anyhow, I bet the oval TB flows more air as
well.  I tried fitting a piece of round reinfoced hose that works with the
oval units on the round and it was to big.  About 1/4" diameter difference
I would guess.  Thats a big difference in flow.  I noticed that my
throttle seems to open faster though.  Quicker Throttle response and a
more sensitive throttle so I guess the small part of the Egg Shaped TB
makes part throttle response less touchy.  I actually prefer the faster
response but my 8.8:1 compression ratio could have something to do with
that. :-)  
	I dont like the idea of filling with aluminum weld but I spose it
would work fine.  Actually, I spose it would work in your example, but I
wouldnt want to go the other way around.   Either way, I noticed the
WOT/Idle switch thing too.  Wonder what others did here.  Gary said he
used the MC TB.  (I think he did, cant remember for sure)  ANd I know Pat
Martin did.  Anyone else use an early Manifold/TB with MC harness.  I'm
using the early stuff but I have a KH harness that works fine with its own
WOT switch setup.  (simple but beefy.  Much bigger than the 5ktq MC setup)
	ANyhow, I'll shut up know.  Need to write a paper.
