intake carb?????
What do you guys think of the performer air gap #2601 made be edelbrock. Or the performer rpm #7101. I was thinking about running one of these on my 350. Will they be to big for stock heads. Also what size carb would you recomemd, my friend had a 750 and had to jet it down a bit.

Re: intake carb?????
I am running the air gap not sure what part number but is described as idle-5500. I love it, a 750 is way to big you will get much better low end and response with a smaller one 600-650.

Re: intake carb?????
The Air-Gap intakes are great intakes. The dual plane plenum provides plenty of low end torque where you need it and the higher rise with the air flow design underneath the plenum makes great higher rpm power for top end performance. The Performer RPM I had on my stock 350 worked really well. I couldn't tell any difference after I swapped to a Performer EPS, which is also a great intake for stock or mild small blocks. The 750 will be too big. Jetting only plays a small role in tuning a Holley. A 570 Street Avenger Holley works well on stock 350's. Do you have the stock cam in your engine?

Re: intake carb?????
Glad to hear most are happy with the air-gap intake. I have been looking at them, but not sure about them. I have the reg. performer now (good intake), but want the rpm air gap (I like the concept). I can see where they might be a little cold natured though. Was this all the time, or just a longer warm-up time?
Oh, yeah the 750 would be good only on a Highly modified 350. I use a street avenger 670 on mine. It's a little rich, but not for the new motor that will go in before long. I just didn't want to buy two carbs. One for the mostly stock motor I have now, and another later. If it's gonna stay stock, or close to it, a 570cfm would be perfect. Jay

Re: intake carb?????
No problem with warm ups and the air gap. If your not going really big with the cam and rest of the valve train a 600 will work great. I have 400 plus and I only use a 670.

Re: intake carb?????
I have stock heads and my cam is at the most 2 steps up from an RV cam, so I dont' think that is very big. Is it worth it to buy a used Edelbrock and rebuild it if the price is right. I have a used 600 I could buy but I would want to rebuild it.

Re: intake carb?????
I don't have any exp. w/the edlebrock carbs. but by the way everyone talks, those things last a lifetime, with no tuning or rebuilding necessary. At least that's what they say when someone wants to buy a Holley.LOL
I'm sure the 600 will work just fine, whoever the manufacturer is. Even if it has to be rebuilt. I would investigate the rebuild cost of that carb first though, and factor that into the final cost of the carb. You might get off cheaper just buying a new one. I've personally never seen any parts offered for Edlebrock carbs, but my limited interest might be a factor as I run a Holley. Jay
