Hello all, finally building a 302 and was just curious as to what the general consensus was on carburetors. I know some of us are die hard brand fans, but I wanted to know if there was a general preference. Also, same deal on an intake manifold as well. I was looking at a Weiand or a Edelbrock but I'm indecisive on these performance parts. Cheers, Nick Also, budget of about 400-500
if I remember right weiand is cheaper than edelbrock Ive had a holley contender intake and a typhoon and now a weiand intake they all have different performance styles. dont worry about brand just worry about the best design for what you plan to do with your car. as for carbs Ive only put a good amount of use on an edelbrock myself BUT I now have a holley that worked very well on my sons maverick he upgraded to a quick fuel so I decided I would try his old carb for a minute see if I like it
I prefer Holley carbs and Edelbrock intakes. Getting ready to take the Edelbrock carb off of our '75 Comet GT and replace it with a Holley because we aren't happy with it.
I've had good luck with both carbs, each works well in certain areas. I had a 350 in my Chevy truck that the AFB/Edelbrock was perfect on, decent mileage and great drive ability. On my GTO, the carb of choice was a 750 double pumper, out performed every other carb I ran on it. Just remember to follow Junrai's advice, match your components.
Edelbrock Torker 289 (the old twisted carb mount type) is a decent all around street intake. And call me crazy but I loved the Holley 4010 4011 types (very simular to the Ford 4100s) The Holleys are my choice. I don't know that much about tuning the AFB EDEDELBROCK AND QUADRABOGS. I've heard if tuned proper they're good.JM2C
From my experience it is hard to beat both in price and performance a Weiand Stealth intake in combination with a Summit 600 vacuum secondary carburetor on a 302. I ran that combination for several years until I upgraded to a Speed Demon 650 carburetor to improve my ET at the strip. The Speed Demon is more temper mental than the Summit unit but it sure does perform! I run a 1 inch spacer and a drop top air cleaner with no hood interference problems. Check out the product reviews. I've included a link to Summit Racing for both pieces: http://www.summitracing.com/parts/wnd-8020/overview/ http://www.summitracing.com/parts/sum-m08600vs/overview/
Seeing Edelbrocks casting and machining quality start to go down the toilet in the past 10 years has me voting for the Weiend. As Hotrock said above.. pretty hard to beat the old 600 vac sec setup. Not to mention that parts and tuning is much more mainstream and advantagous than the mileage improvements that can be gained from the Edelbrock carbs.
For any 302 build ? Any of these: Weiand Stealth, Edelbrock's Twisted Twisted Torker, F4B, Performer RPM. Then there's Ford's intakes, including the C9OX, A321 (Ford Racing's newer version of same) Shelby "Cobra". Then there's the multiple carb setups Ford put out : 3x2 (have had this on my 331 for 11 years, with nary an issue or adjustments) and the 2x4. The 3x2 will work on a mild 302 build as it has a progressive linkage (center carb is the primary, ends are the secondarys) mounting three Holley 250 cfm carbs. As far as 4 bbl carbs go, any new or barely used Holley vacuum secondary carb of 570 to 650 will do. A 3310 750 will work too in a pinch. But take the time to learn how to tune it and how it functions before you do anything. Most who complain about a Holley never do this, they just bolt it on and expect it to work at 100% right out of the box. Ain't seen any carb do that yet. Bought a few used ones that were victims of this that worked perfectly after a cleaning and adjustments.
Very true but I got lucky once, bolted on that 750 DP in a hurry to hit the strip and went from a best of 12.35 @ 104 MPH to 11.88 @ 114 MPH. What did bite me in the rump was the choke, I neglected to attach a choke cable or tie it open and it closed after my second pass killing the engine!
I was running a 600 CFM Holley before I replaced it with the Summit Racing 600 CFM. There was a big increase in performance over the Holley. In response to groberts101, prior to installing the Weiand Stealth I had installed two new Edelbrock Performer RPM manifolds. Both installations exhibited what appeared to be vacuum leaks. After the removal of the second Edelbrock manifold I did what I should have done in the first place. I laid a machinist's straight edge along the machined surfaces where it bolts to the heads and found the left to be high at the center. What is the likelihood of purchasing two incorrectly machined manifolds? I bought a new Weiand Stealth checked it for strightness, problem gone.
Been there done that. That's why I completely remove the whole mechanism right off the bat. With a good hot ignition and the timing set to 10-14* BTC, I've found the choke is pretty useless. Give it a pump shot or two and baby the throttle a minute or so and it's good to go except in really, really cold weather.
