[DeTomaso] New Carb - Recommendations?

[Erik Anderson]

I find it interesting that Holley currently markets 670cfm and 750cfm
carbs.  The ideal mix for the 351c would seem to be in the middle
(around 700cfm) and with my engine having upgraded internals I am
reluctant to head south of the 700cfm mark.
 
Mike, do you find you have to tune Larry's carb often?

So, I'm interested to know ...

- What carb are you currently running in your 351c?
- What do you like / dislike about it?


I have one of Larry Stock's custom 700 Holley double-pumpers on my
moderately built 351C and I *love* it.  Comes with lots of features
(electric choke, braided fuel feed, all-metal construction), and was
very close to perfectly dialed-in right out of the box.  I had a tiny
bit of lean surge at part-throttle cruise, fixed by going up a couple of
sizes on the main jet.  

Now it's flawless, except that it's too rich on the idle circuit.
Easily adjusted, when I take the time to do so.  Returns 17 mpg on the
highway too..

FWIW, if you bought a standard 700 double-pumper, then bought all the
extra additional bits that Larry includes with his carburetor, it would
be *much* more expensive.

Larry has changed carburetor builders a couple of times since I bought
mine from him; originally Holley's custom shop was making the carbs for
him, but they issued an unannounced design change which totally dorked
them up, and resulted in a lot of unhappy customers.  Larry had to take
numerous carbs back and have them fixed.  He changed providers, and now
has an outfit that I believe is staffed by former (disgruntled) Holley
employees.  No problems for the past few years.

I think Jack DeRyke has the same carburetor on his Pantera and is
similarly happy?

Mike
