Double pumper.....

Hello all, im in the market for a carb and Im leaning towards a holley 650cfm ultra double pumper. Can my engine handle it or is it to big? the whole engine is bone stock.

Ok thanks! i have never understood carbs and the cfms. So thanks for the help, I like the ultra series but the only come in 670cfm, should I get that or just an aluminum street avenger?

HAHAHAHA yeah, I asked this question on the diesel stop and they were giving me these complex formulas and stuff. I think that i would probobly get the holley because i hade an edelbrock once and I just couldnt tune it! Im planning on an everyday driver, but I want to beat the heck out of a ricer every once and a while

Thanks, I have never heard of this company before and im already sold! I was looking at them and I really like the 575cfm speed demon, it seems to have everythin that I want! In the near furture(next fall) I am going to replace the cams an install msd. Is this a good choice? I am kind of worried that its too small,but coming from a diesel boy, what can you expect! Do you know what cfm the stock 2v carb is?

The 575CFM Speed Demon is a good choice and it should work well with future go-fast parts. CompCams has free download cam selection software that helped me pick the right cam for my engine. The more realistic information you enter about how you'll be using your car, the better cam choice it'll make for you.

I just did the Comp cam Picker and the best cam for my car is the 270HR!

Unless you are really interested in the rev limiter (I was), or are running crazy compression, the stock Duraspark distributor, properly tuned, and Duraspark box, is fine.

I just realized you have points... so ANYTHING is an upgrade.

Ok cool, I was either going to do an Msd or Aurora ignition but im not going to be racing so I guess i dont really need it. lol. What exactly is a rev limiter, i thought it stopped the engine from over revving but it does more? thanks

Ok, then i definatley want a rev limiter, my buddy had a bad experiance with over reving an engine and i dont want to go through it. I am leaning towards msd right now because i cant find that much info on the aurora.

The 650 would be an ok carb for that engine being a street car. The main thing is match it to a decent intake. The dual exhaust will help things run better and sound better too.

I have an older version of the performer, with a 600 cfm Performer {carter} carb.

This is what I bought for my 351CJ but I haven't tried it yet. They're factory rebuilt, that's as good as new to me.  One with a manual choke is $25.00 cheaper, but I like the electric one.

Thanks, Stanmam,  I need a spread bore though! and I was thinking 600cfm or 650cfm If you guys are getting 600cfms for a cj, then maybe I sould for my 2v. This stuff is very confusing

No worries.

Thanks for the kind words.  I'm angling to be the #1 source of Torino parts on the forum.   Paul~
