Converting to Carb - Holley 650 DP 6498?
 

I can get this carb for 60 bucks shipped to my house but it may need rebuild. Is this a decent carb to start off with? I have a post 87 350 block so I will be getting the 2704 performer intake and dizzy. I just want something that will give me a little power and easy to tune etc. I am just looking to get into the low 13's. Nothing too big.

I guess it came out of a 1967-71 Plymouth?

Cross referencing says that it's the same as the 4165 holley? http://www.summitracing.com/parts/AE...n/?prefilter=0

what is dizzy?

Re: Converting to Carb - Holley 650 DP 6498?
 

Distributor. I don't know what kind, just collecting parts practically hahaha.

Re: Converting to Carb - Holley 650 DP 6498?
 

yup 4165 650cfm.

Why not go with the rpm air gap?

Re: Converting to Carb - Holley 650 DP 6498?
 

50 bucks a good deal?

Which is better? the air gap or performer? Much of a difference? If so what is the difference?

Re: Converting to Carb - Holley 650 DP 6498?
 

Not a bad deal but you will still probably have to drop another $50 on a rebuild kit for it.

The performer manifold's operating range is idle-5500rpm
the rpm air gap is 1500-6500rpm

the air gap has a gap under the runners for air to flow under and allow for cooler air or something like that. I would guess that they have a little longer runner.

Well I don't plan on over working my engine. I normally shift at 5k cause I am unsure what my redline is lol. So the performer would have more of a range that I use am I wrong?

I'm still learning bare with me :P

Re: Converting to Carb - Holley 650 DP 6498?
 

Yea the performer would be fine for ya.

However the 4165 is a spreadbore and single inlet. :\

Re: Converting to Carb - Holley 650 DP 6498?
 

What does this mean? Single inlet as in only 1 fuel line to the carb?
Whats spreadbore?

Re: Converting to Carb - Holley 650 DP 6498?
 

Square bore- The 4 barrel carb's front and rear throttle plates are the same size.

Spread bore- The carb's rear throttle plates are larger diameter (like a GM Quadrajet or Chrysler Thermoquad)

The performer says spread or square bore so I don't see the problem. Are spread bores bad?
If so in what way?
Would I have a pretty decent combo with the performer and this Holley 650 DP?

Re: Converting to Carb - Holley 650 DP 6498?
 

No sorry its late here I just noticed the 4165 was spread bore.

The rpm air gap is for a square bore. Personally if it was me I would try to find a holley carb 4777 (650cfm double pumper) along with the 7501 edelbrock.

Alright, I am not completely ready to convert yet. I still need to convert transmission to Standard haha. But it'll be next thing I think.

Thanks for all your help though! Will be bookmarking this for future reference :P

rule of thumb (though not set in stone) auto trans - vac. sec standard = D.P.
you also have to figure in driving habits. if you have a heavy foot, you better have gas $$$ if you get a D. P.!
