I have a Holley 770 Street Avenger carb on my '69 with a 454 and a
TKO-600, and it's been great, right out of the box, and a simple adjust
of the idle mix screws. I was always pleased enough to NOT mess with
it. Then I took it to shop for some head work, and they tweaked the
carb a bit more, and now it starts and runs like a dream. Starts right
up, and I can drive away, even in cold weathe (electric choke). No
hesitation. It just works, which is a nice change.
take care,
Mike

Anyone have anything good to say about a Demon carb? I went from a
worn out Holley 650 DP to a 750 Demon w/mech secondaries but the 5 mpg
was to much! Swapped it for a 650 Demon with mech sec. Mpg up to 10
-11 mostly highway which I can live with. Neither was an out of the
box job. Both needed alot of work. Low end drivability is not much.
Going thru the gears & top end is great. Won't idle til completely
warm and a PITA at all stops. Got to keep the revs up to take off.
Feels like a close box & no rear gears. Well it's a 252 first & a
3.73 rear. Cam is a Comp 274 Hi Energy Xtreme, 236 dur 490 lift.
Down from a 284 in the six yrs I've owned it. The guy at BG says too
much cam & go to a 575. Wouldn't that kill the performance!!! I've
got a TKO 600 with a 2.87 first going in this winter which may solve
it all and give me both low end drivability & 1/4 mile performance.
Why don't I go with an Edelbrock which most people say are great right
out the box? Probably the Look. Some of us just prefer the
Holley/Demon look. All thoughts, comments, ideas, advice, or just
ventilation appreciated.
For anyone that was at the MCC/ACES show at North East, MD Sat and/or
Sun, wasn't that "Some Show"? Over 200 Chevelles, great weather and
great people. That loaded 383 stroker that was given away kept
most everyone til the end! I applaud the MCC leadership and all my
hard working fellow and fellowette members for another terrific show
and a Great weekend!!!

The 600 cfm vacuum secondary Holley is the most inconsistant pita carb
I have worked with. If you go holley make it a double pumper.
Quadrajets and Edelbrocks will work well too.

I know what you mean Howard...My 327 has a mild cam..465 lift 224
duration @.050 on both intake and exhaust...headers...roller
rockers....weiand stealth dual plane intake and a couple other small
bolt-ons...I know Holleys are good once you get them right..but man..I
just can't seem to find that spot..I've just heard that the Edelbrock
is a much more forgiving carb if you know what I mean...
