my friend has a edelbrock performer 600 cfm manual choke carb that he is selling for 100$ i am fully confident that this carb was worked on by my froends dad who i know had kept good care of it and tuned it perfectly for his chevy 305. he had new metering rods put in it to little more gas flow and it has 2 pvc ports into the carb which he says 1 can be pluged with the pieces that came with the carb. would this be a good idea for me to get. i have a little hopped up comp cam extreme energy cam and flat top pistons. it is also bored 40 over from a 289

 

if it is good shape, i might consider getting it, but maybe changing out the rods for smaller ones. 600 is high for a 289, but if you got good heads, and exhaust system it might work ok.

 

it has stock heads with roller rockers swirl polished valves, and springs to match my cam and a flowmaster no cat exhaust

 

It should work, some tunning and it would even be okay on gas. Sure its a tad big, but its an air valve secondary, that means it will only ingest as much air as it needs. Unlike putting a 1050 Dominator on a 289, because they have mechanical secondaries and the throttle opens all the way when you stomp it.

Vacuum secondaries or the air valve system on Q-jets, and Edelbrock carbs are capable of tunning the bog out by slowing the opening of the air valve. You can also increase the opening rate to the point of a bog, then back it off so you know you are getting all of the performance from it.

 

The price of that carb is a good and fair price. I would buy it if in need of a performance carburetor, then install it. If it turned out to be too much carb, then either add more performance parts to the engine, or sell it on Ebay for at least that price. You can't lose.
