very good carb

Summit RacingSummit Racing Verified Purchase

I installed this carb on a 79 Chevy truck with a mild 350. It came out of the box looking great and was a straight forward install. It is much lighter than a conventional carb and the clear fuel bowl glasses are very nice. I did have to adjust the floats, idle mixture screws and work with the choke to get the fast idle to come off. Typical adjustments I would expect to perform on a new carb. ...read more

Holley 670 Street Avenger Ultra

Summit RacingSummit Racing Verified Purchase

Carburetor installed on 327 10.5:1 compression, 408 hp provided much more performance than Edelbrock 750 (1411). Tuning Holley requires patience and a good understanding of your engine but solved boiling fuel problem after all other variables controlled. For my application, this carb was the right choice.

Great carb

Summit RacingSummit Racing Verified Purchase

This is a great looking carb that worked very good out of the box with no adjustments. I was having problems getting my engine to idle with the cam I am using, but the 4 corner idle on this carb fixed my problem.

Not great out of the box

I have a GMPP 350 crate engine with Vortec heads, Nothing special. Put the carb on and had HUGH stumble in it. I originally thought it was too small a accelerator pump shot but after researching online I found these are jetted really low out of the box. 65 primary and 68 secondary. I found many posts about this (and accelerator pump arms not being adjusted correctly from factory) after going to 68/72s the car was drivable. I'm currently at 72/74 and now it finally runs "right" and plugs look good. The point of all this is; BE CAREFUL! The lean jetting this carb comes with could cause damage if your not careful. Most people report 70/72 main jets seem to be about right. I rated the item down on value due to having to purchase so many jets, discharge nozzles, gaskets, springs, cams, etc. It DOES run stronger than my 1406 Edelbrock though,... After tuning. ...read more

"Out of the Box" ready to run?

Summit RacingSummit Racing Verified Purchase

Let me start by saying that after some tuning, this carb does perform as advertised. I'm very happy with the performance increase over my old Edelbrock 600cfm 1406. When first installed,the Street Avenger would not fire and when it finally did, it ran horribly! I went through the factory settings and found the idle metering adjustments to be different on all four corners. They ranged from 1/4 turn open to 1 1/2 turns. After setting all 4 to 1 full turn, I reinstalled it and it fired right up! I was able to tune from there. I would suggest everyone check the factory settings prior to installation to avoid the problems I encountered. Don't assume that Holley got it right before shipping. ...read more
