Well, I'm getting sick of the Nikki carb, tbh. I think its what is giving me my troubles and rebuild kits are a fourtune and a half. I've heard mixed feelings about running a holley, but my bud has been convincing me. I really love all the options and everything you can do to a holley. Plus, I'm in a conquest for power and am detirmined to hit 15's.

The thing I'm worried about is how much harder would be getting a holley to work than getting the nikki running good and naked? Is the 600 too much for a stock port 12a? If so, where is a good place to get a 465 or 500 four barrel? Will I see much more performance going with a holley? And what type of gas mileage and driveability will I see with a holley? My car is driven about 50 miles a day 8 months out of the year so I wouldn't want to do anything that would get me any worse than 20mpg.

Thanks!

check out www.racingbeat.com.. they have the 465 cfm for stock port and 600 cfm for streetport. i used to have the 465 on a stock 83 12a and it was like night and day over the niki. currently running the 600 on my sp 74 13b. they run quite abit rich tho. i can get around 16mpg as long as i stay out of the secondarys.

600 CFM is too much for a stockport 12A. I have a GSL-SE (6 port 13B) with the RB intake and an edelbrock 600. Awesome combo. I haven't had it legal long enough to get an idea of the fuel mileage, but the driveability is great. I prolly won't get an accurate MPG number on it for a while, have too much fun with the loud pedal while driving it......
I'm seriously considering getting an intake for the 12A, and topping that with another edelbrock for my 83.
I am no fan of Holley carbs, but I am quickly becoming a fan of edelbrock carbs.

Nikki rebuild kits are around 30 bucks at AutoZone. Buying a new RB Holley is what, 20 times that? You don't list headers in your mod list, start there or you'll simply waste your money on a carb upgrade.

The holley carb will do you no good until you upgrade your exhaust, but after that they work really good and you will notice the difference. A 465 is enough for a stock 12a.

Headers are coming this winter, as with a full exhaust. A holley would be a winter project as well. I'm going to do all the bolt ons, and hopefully hit 15s. I just got a rebuild kit from autozone, too.

So does anybody with a 465 know what they were getting for mileage?

You really ought to take a look at Sterling carbs. About a third of the cost, and built specifically to perform on a rotary engine. www.sterlingmetalworks.com
