Re: choosing the right carb
I personally love Holleys. I'm not a fan of Edelbrocks. I like q-jets too in stock or mild performance setups. I have the stock q-jet on my truck now and daily drive it. On my last three builds I ran Holleys. My last car, 66 Chevelle with a 383, mild cam, 3:36 gears, 700r4, stock converter, 26 inch tires had a 750dp which is not the right carb for that at all, but it loved it. I tried a 650dp, 670 street avenger (vac secondaries) and the 750. Drivability was the same with all three, but the mpg was the best with the 750. 18.6 freeway, 15 combined. Go figure. Just have to find what it likes.
20 years ago back in high school I had a 66 Chevelle with a 468 and a 4 speed. It was a mild build, but still ran high 11's. 850 Holley double pumper. All my friends ran Edelbrocks. The used to tease me that I was always working on my car and I was. Every day after school I was under the hood trying to make it run better and faster. They said Holleys never keep their tune blah blah blah. One day I said to my friend with a 69 Chevelle with a 454 and a 750 Edelbrock, "Ok, let's swap carbs and you tune mine and I'll tune yours then we'll race." He had never beaten me before. His car ran consistent 12.20's and mine ran 11.80's all day. We did and when we raced we were fender to fender. Never got time slips, but mine just felt slow and he was shocked how fast his felt. He got a Holley the next week never looked back. Oh, and he ran 11.90's next trip out.
