Price	$270
Pros	High Output, good mileage for a carb, clean and easy to work with
Cons	Floats got stuck open when I first ran her, not FI
Recommended	yes

Comments: 670cfm - The application I am using with for is a 89 YJ with a AMC 360 inside. Mainly my daily driver but also used to have a little fun now and then. Seems to run smooth, good on cold starts, doesn't seem to east as much fuel as other Truck Carbs. I have a "Jeep" billet air element with a 13in. K&N Oil Air Filter on it (E-3698 if you were wondering)

Price	$375
Pros	Automatic choke works well
Cons	650 double pumper.. actually dumps a little too much fuel to the 304, had to re-do jets
Recommended	yes

Comments: As the list is limited..
What I have is actually a 650 double pumper.
Sit's on a AMC 4barrel intake. Had to redo jets to prevent rich running & flooding problems

Price	$350
Pros	Lives up to what holley says. Resists bogging well.
Cons	I had a hard time dialing it in. Always wants to run rich. Probably a bit to big of a carb, even for a stroker?
Recommended	yes

Comments: Good Carb but a lot of tuning comes with it as you may know. Hasn't bogged on me and good throttle response. No real complaints once I got it tuned properly.

[hutch1200]

Price	$150
Pros	Poor mans EFI.
Cons	None yet
Recommended	yes

Comments: Buy the re-manned unit, or wait for a sale. MSRP of $450+...puleaze! Got my 770 for $150 on ebay. Called and the guy & he hated it. My bud is a old dirt tracker. The jets were Huge, like it was set-up for alcohol! Since I've only had dyno time on it, and it made over 400hp I'm happy so far. Seems easy enough to tune/jet which I'm sure I'll have to do for street/trails.
(It even has the vacum port for the tailgate switch )

[Bullfrog80]

Price	$399
Pros	Can run steep hills without flooding/sputtering out.
Cons	Hurt mpg... lol. (like it was great before)
Recommended	yes

Comments: Poor man's EFI. It is amazing how well this carb does at extreme angles. It is night and day from my old edelbrock. So far it hasn't been the reason I back down from a hill. I wish Holley offered a 570 cfm model. The 670 was a little much for my 355 sbc but after rejetting and tuning it works well. I would highly recommend this carb.

Price	$300
Pros	Great for climbs
Cons	Gas killer
Recommended	yes

[Deepair3]

Price	$250
Pros	Awesome!!!! Easy to tune. Runs like a top.
Cons	None
Recommended	yes

Comments: I bought this used. It took a little tweeking but I got it back to stock specs and tuned from there. It sits on top of an AMC 360 and this carb made a huge difference in performance over the Edelbrock that was on her when I bought her. Not to knock Edelbrock because it was in pretty bad shape.

Price	$375
Pros	Great carb. Starts right up. Not stalling on inclines.
Cons	Price - but get what you pay for. Had a edelbrock 650 on it before- always had a float issue from the start out of the box. Was great on the road, get off road was a awful carb.
Recommended	yes

Comments: Current set up is Holley 650 with edelbrock 2130 intake manafold.
