I had a big dissertation written, but I decided to get rid of it. I will say that statement isn't always true

If you do go edelbrock I could see how it would cost you $100 to get it dialed in if you bought individual rods and jets, but if you buy the calibration kit it's between $30 and $70 and has everything you should need. Also ask around, see if anyone you know happens to have a calibration kit.

When I originally set mine I borrowed a complete calibartion kit off of a repair shop (i know the guy that owns it) with the understanding that i could use it as long as i needed to so long as it came back with all of the same jets and rods that it left with. I got the carb set, bought $14 worth of rods, and got it back to him.

That plan works great around here, too!!!! I loan mine out to friends wanting to dial in their Edelbrock, just charge them for the pieces they use..... I prefer Edelbrock carbs for the street, and Holley's when it's time to go racing!

Used to run a Q-Jet on a Windsor with a tweaked, trimmed, and smoothed adapter as described. Had a friend who was an old NHRA Super Stock racer who ran chebbies and was very, very good at setting up the Q-Jets.....He died a few years back, I switched to Edelbrocks...but a Q-Jet set up correctly IS a great working carb and those tiny primarys will knock down some decent MPG if you keep your leg out of those giant secondaries!!!! I've never been too good at keeping my leg out of anything I drive!!!!!! LOL

Fond memories of the 70's-------My friend's mom's 73 Impala, high compression 350, Q-Jet, with the air cleaner lid flipped upside down-----him nailing the throttle downtown (small town in east Texas) between the buildings................................ It would bog down and rumble, then all the sudden.....................BoooooooooooWoooooooooo ooooooo!!!!!!!!!!

It was back in mid 80's I helped a friend fix an Oldsmobile for his mom's friend. It was a 4 dr grandma hot rod, rocket 350 that the intake had cracked. We put a Ebok performer on it and that ol car would fly! Blaze the tires for as long as you wanted to.

I ran a 750DP Holley and pulled down 16mpg out of it. Its all in how you have your engine tuned and how light you can drive with your right foot too LOL.
