Need some input fellows,What carburetor do you reccommend me put on my 347 stroker motor? My mechanic buddy is a Holley man, but feels like the Edelbrock is more reliable. He thinks I need something around 750 cfm. I have AFR 185 heads. His thoughts are the holley will give you about a second better time at the track, but the Edelbrock will be hassle free for years to come. I'm building the engine for street/occasional strip. Please give me some feedback. Thanks,
Barry

Holley 770 Avenger will do very nicely.  ------------------

If its mostly street I would personally go with something a lot smaller. Maybe around 600cfm. You should get better lower end and better throttle response. Now if it was mostly strip, then yeah bigger is better... David F.

Thanks for the replies men,I'm not real clear on why the smaller carb will give better throttle response. If I went with the smaller carb, would I be severely limiting the cars potential? Barry

I chose a 670cfm avenger holley for my 351W, but it's mostly stock, with the afr heads you have, i would say a 750+ such as your buddy mentioned, or the 770 Avenger Alex mentioned. The avenger is a vac secondary, which also could allow you to run a bigger carb than you need without hindering performace. Most holleys don't need adjusting once dialed in, so i'd go that route, as the edelbrocks are proven to be an inferior carb for performance, where as there isn't really proof to say you need to fiddle with a holley.

Not that I am a carb guru, but I have had good luck with a 700 double pumper on 350 or so motors....

I am right on the verge of breaking into the 11's with my mildly built 347 in my '66 Mustang Coupe. I also have AFR 185's and I am running a Demon 650 vacuum secondary carb. That being said, I would go with a 750 or 770 VS carb for a mostly street and some strip action. That way you know you have plenty of airflow for your engine.------------------

I stated with a BG 650 on my 347, could not get rid of the over rich idle and poor performance even with BG tech help. Went with a Quick Fuel Technology 750 dp four year ago and have not regrets. QFTs look like Holleys only better. The owners of the company are x-Holley engineers, one of them was the designer of the HP series. ------------------

Good info Concensus seems to be going with the 750-770 range. I'm chomping at the bit to get started on this project, the friend (buddy that's a mechanic)that is going to help me has had to delay us getting started because he is really busy at his shop. I've got most of the major components that I need. The machine shop is going to do most of the engine work. Barry

Well, the Holley Street Avenger 770 it is, just ordered from Jegs, along with a set of tall valve covers, and MSD ignition and coil  Hopefully I'll get all this stuff in before the little MRS. figures out what's going on  Barry
