I currently have a Victor Jr Intake on my 306 with a 600 CFM Holley Double Pumper. Its a single plane intake and I am wondering if it would be better to go with a dual plane due to my car seeing mainly street driving. What benefits / negatives would I see in swapping to like a performer rpm?
The car has a 306 with stock heads (as far as I know), Z cam, BBK Shorties, BBK Offroad H pipe and 2 chamber flows.

Only thing I could tell ya from my chevy days is I always liked the single plane intakes better. The dual planes have become better but, I still think the singles givemore performance over all. You might pick up a lil torque on the bottom end with a performer rpm. But for the price of the swap it isnt worth it to me.Originally Posted by ArmyWarrant
I also just read that it is recommended to run a 750 or bigger carb on a victor jr. 750 cfm is to big for my engine, Anyone else have any suggestions thx Hidalgo

How is the car running with the current set up? I used to run an old torker with a 600 douple pumper and it worked ok. I run a 750 dbl pumper on a dual plane with a 1" spacer(intake came on the motor not my choice so I added the spacer). Plan to put a victor jr on it when I redo the truck. If your car runs fine now and doesnt load up or bog then I wouldnt worry about it much. If you knew someone who had one laying around you could try a swap to see if you gain anything. Being your heads aren't large port heads I dont think you have to worry about the 750 recomendation.
It doesn't bog or anything I will stick with it for now and see how it does. Thx

Well I pulled the valve covers today and found some good things, they are not stock heads. They are World Products Victor Jrs with stud mount roller rockers. I keep finding more and more good things about the car the more I check it out.

Could be why you havent had any issues. Other thing you could do is get a temp. gun and check each header tube see if any are hotter then the other front/back and adjust for that if the carb has the 4 corner idle screws. Seems like the combo is running well. Had it to the track yet?
I haven't had it to the track yet? It's an hour and a half drive to the nearest track. I want to try to get to the track this summer and see how it does.
The carb only has the 2 idle screw that i've seen so thats not an option. I am going to rejet it with a friends recommendations and see how it does.

Ya PRP is about 45 mins give or take a cop or two.
Well I drove it for the first time on the highway and wow what a difference it makes when you have a car that is built right and no shody machine shop work. This thing pulls great all the way through the RPM range and I didn't even get over 5500 rpm in it.
All that is left is to get the carb jetted to better match the setup. It smells like it is running rich and every once in a while it puffs a lil smoke when its been idling for a while like its loading up.
