i have a SBC 350 with dart iron eagle platinum heads. 200cc and 64cc chamber. Edelbrock performer intake, Edelbrock TES headers, and lunati 60103 cam. I currently have the edelbrock 1406 carb which is 600cfm and im pretty sure its not gonna be big enough what carb size and brands do you guys suggest?

 

That Edelbrock should be fine.

 

First, what are you using the car for? Cruising? Daily driver? Track-only? Street/strip?

You have pretty big heads with a fairly large cam. The powerband advertised by Lunati is 1800-6200 RPMs. The standard carb CFM formula is CID times max-RPM divided by 3456. Plug your numbers in, it comes up to 627 CFM. That assumes 100% volumetric efficiency (rare) and single plane intake manifold. You have a dual plane intake, which effectively splits the carb in two, meaning a little larger carb is usually required to get max power.

If you are primarily racing the car, then get a 650 double pumper Holley. If you're only cruising with it or driving it daily, your current carb will suffice.

BTW, your intake manifold is a mismatch with your cam & heads. You should be running a Performer RPM.

 

its going to be daily with some strip use.

 

and yea i do have a mismatch intake i dont have these parts on yet just getting everything rounded up before it goes on. I have the EPS intake which is only to 5500 rpm so ill be looking for the rpm one

 

How much stall?

Your user info says TH350, is that correct?

 

yea around a 2600 stall and yea built th350 with full manual VB gears im unsure on but am looking for a posi and around 3.73 gears

 

with that stall and either 3.73 or 3.42 gears still the 650 dp?

 

With stock stall you could put a 750 DP on a 350 without problems.

 

its a 2600-2800 stall.

 

I know some people would disagree but I would do a Holley 750dp. My car has a 750dp/HP and a Weiand team G single plain intake and I wouldn't change a thing but my car is not a daily driver.


Mark.

 

I run a 750 on mine as well. Only difference is I have an Airgap RPM. Aside from that - everything else is identical to his build for the most part.

 

well will my 600 suffice for a while till i get enough money for a bigger one?

 

Yeah, you'll be fine for now.

 

A holly 650 dp would be big enough right? the 750 will just be big enough for future uses?

 

i had an arguement with a good friend of mine because i wanted to run a 750dp. he told me that the 650dp i have now is plenty for my motor. and i have fully ported heads also
