Default replacing rochester to edelbrock on 350

Hi Guys,

I have a rochester carb and thinking of replacing to edelbrock.
Can anyone tell me what edelbrock model is recomended to my 77 automatic 350 vette?
Do i need to replace the carb mount to do so?

Thanks, A.

You would need a 600 & another intake as there really is not enough room w/ adapter for a perf. setup. Al. intake & Holley rec.

I have a 1 " adapter under my Quad. with the dual snorkel intake on my 77. The air cleaner has a little less then a 1/4 " from hitting the hood. I also have a solid motor mount, so the motor does not move under acceleration.

So what, the adapter does not help stock auto. either! Closest point is at front of air cleaner.

An Edelbrock 1406 carb with an Edelbrock Performer EPS intake fit my 1979. I use a .2 Holley gasket between the carb and the stock dual snorkel air cleaner.Edelbrock claims that the EPS intake produces more power and torque than the Performer intake, and it is made for the Edelbrock carb so an adapter isn't needed between the two.

A change to an Edelbrock carb is not an upgrade in any sense of the word. Why do it?

Yes, the EPS intake is a good way for someone that wants to go square bore carb. w/ mild setup.

So you say. Everyone has a right to their say and beliefs, some people know their own motors and can hear/feel or see a difference.

I'm with "Mike" as go and change to an Edelbrock(Carter AFB upgrade), as know some here running well tuned Q-Jets willing to travel a bit to grab some easy street drag money. That's only if they slow down enough to actually have some idea where you are.

I've given them a few tries and never liked them. If you absolutely need to swap out the Qjet, get a spreadbore Holly

Its the opinion from just about everyone I know and not even a choice when getting a carb.
I like Holleys, I can make them work just fine.
I have a 600DP on mine now and it flat out rips!!!!
When I got the car I had to take it apart and clean it out and change the power valve that looked to be blown for a 100 years, added non stick gaskets and adjust the needle and now I don't touch it.

Why are you wanting to change the carb? What is the issue or symptom?

The same reason people use a K&N air filter, I think. Bragging rights and the perceived 5, 10, 20 HP gain on the butt dyno.

A well tuned Q-Jet (750 cfm) will shame an Edelbrock.

I am right there with you on the Holley!

Thanks guys.
I believe some more clarifications will be in place here:
Have a 2601 edelbrock intake manifold with a stock, stutterer, nonfunctioning left Dizh, roachester carb. and need to replace or rebuild.
rather put in a new one.
considering putting an edelbrock to match the intake manifold.
can obtain a roachester with holley inside (first time i've heard about it. is that for real??) or a 1406 edelbrock.
can't get a holley here (Israel...).
my mechanic recomend the edelbrock over the roachester.
don't mind fuel economy, rather have more HP.
any sugestions?

With an Edelbrock carb you're likely to have less of both. The rochester with holley inside is just a q'jet rebuilt by Holley which they did for awhile if I'm not mistaken.

If you can get an edelbrock carb I dont see why a holley would be unavailable but you certainly would know better. I'd go with the holley rebuilt q-jet if my only choices were that or an edelbrock.
