I need suggestions for carb. I have on hand an older, much older, Holley 600 and also a not quite so old, maybe 5-6 years Edlebrock 750.

I am looking for opinions on using one of these, rebuilt of course, but also what would be the ultimate new carb for this setup?

1973 Plymouth Satellite Sebring. Will be mostly a weekend street car.

Engine specs:

Block Bored Honed and decked, went 40 over
New Performance Pistons with Moly rings,
9 to 1 compression
High volume oil pump

Camshaft:
Power range states 1600 - 5750
211/227 @ .050
442/460 lift
110 Lobe center
Matching Lifters and springs

Heads:
3 angle seats
1.94 / 1.50 Stainless valves
Stage 1 porting on the heads
110lb springs

Intake: Edlebrock Performer 2176
4-bbl Spread-Bore
Idle - 5500 rmp

Automatic transmission, not rebuilt yet so I can have it built to mach engine output.


Any input?
Thanx...ajk

Oddly enough, those two carbs should both work. You're not running a lot of cam and with a small displacement, going higher than a Holley 600 vac secondary probably won't buy you much. Since a lot of the Carter carbs have smaller primaries, you might get away with a more flow - but you might get a bog when you jump on the secondaries.

I did run a Carter TQ (about 800 cfm) on my old 318, but it had a little stronger cam, HP intake and full (header) exhaust.

Assuming you are running a full dual exhaust, right?

Cool car, btw!!!

Yes, I think my headers are 1 7/8" , I'll have to look at them a little closer, haven't looked at them since I started in June 2010.
I have heard that using a Quadrajet carb like this one, with the smaller primaries may be the way to go:

I would use the 600..there is nothing worse than being over carbed and having it fall on its face or stall because of flooding. I ran a 600 with more cam than that and never had a problem. with todays gas prices stick with the 600 its not like your racing or anything.

 

Stay 600.

 

Get an Edelbrock 600.. 750 will work but it is too large. With a HV oil pump be careful it can suck the pan dry.. You need a 7 qt pan.. At one time they made a Quadrejet spread bore to replace the thermoquad.
Won't work with your manifold

YA know, they make conversion spacers for that... used to use one...

I know but it is not the best way

Depends. $20 spacer vs $150 manifold. And you get the benefit of a spacer (cooler fuel charge). More than one way to skin a cat, and it worked pretty well on my rig.

A 650 AVS works well in my comb i have the 360 heads 1.88 1.60 ported and a slightly larger cam and air gap manifold.
the avs is a slight spread bore not as extreme as the quad -jet
if they have tuning kits for the quad jet it would be a torky carb
My brother put one on his 440 it cam off a early 70's eldorado with the 502ci
that was the best working carb he ever ran on that monster he just put it on and it worked perfect no tuning.
