Default 87' SS carb and chip questions

tried searching but not to many 80's style SS's, but i have an 87' SS with torque converter, dynomax exhaust, edelbrock headers, edelbrock intake manifold and a crane cam. i need an carburetor and i was looking at edelbrock. any suggestions on which one to look at. i have the 5.0L 305 motor. i was also looking into a performance chip too? any suggestions? i was looking at JET chips, but dont know what to look for. Looking for more hp and torque.

If you want to keep the car running off the ECM, you will need to stick with the original CCC Q-jet and distributer. The ECM controls timing and fuel mixture through these devices which are not reproduced in a compatable aftermarket part. The stock Q-jet is a fantastic carb and don't let anyone tell you otherwise - the small primaries and huge secondaries offer great mileage and performance in one package. The stock Q-jet can be easily modified to flow ~750cfm, but they are originally limited to 600 or so. I run the stock CCC system on my 350, as do many others. Some are even running a big block on the CCC system with a custom chip.

Performance chips aren't very useful for a CCC vehicle since the ECM is out of the loop at WOT - the carb acts like a standard carb allowing max fuel into the carb, only to be metered thereafter by the rods. I have tried a few in my car and you cannot notice a difference IMHO.

www.montecarloss.com is a much more suited resource for those interested in pre-5th gen Montes

I agree with 85_SS on most points. The Q-Jet is an underrated carb and really does do a good job for gas milage and WOT there is no arguing that. But the Edelbrock is better.

I would specifically pick up a Performer series 750 cfm considering your intake manifold and headers. Also the Crane cam will take advantage as well. The Q-Jet can do it and without problems but I just found tuning to be easier on the Edelbrock. Vic's boys know what their doing.

As for the chip I would scrap the idea as you're asking for problems...or at least in my experience Go with a MSD Ignition system to improve spark.

Carb brand is preference, and I will agree the Q-jet does take a bit more background knowledge to tune.

Just be aware that to go with a non CCC qjet, you must completely eliminate the CCC system, including the distributer. This may not be an option if you require emissions testing.

if you have to keep it stock get your carb rebuilt upgrade your ignition system (msd,accel)or whatever and go with a ZZ4 prom that should work . but if you dont have to stick to stock i would go with a edelbrock carb 600-750cfm and i would change to a HEI distributor with the coil in the cap and get rid of the ECU completlely
