Recently bought this car for my wife. All orignial and to the knowledge of the previous owner the car has 96K and no indication of engine ever being rebuilt. Previous owner did a tuneup. New plugs, wires, cap/rotor, PCV and air cleaner. It starts everytime and runs ok on hwy. It does bog down sometime when I stomp on it to get out n traffic. Also will not go past 80-85 seems to cont. Being sluggish at that speed. HELP!!!

sluggish

There is a lot of areas to start with. I guess if I had to pick one I would look at the distributor first. If the points and timing are not setup right, it's not going to allow it reach certain rpms/speeds. Does the car run strong at lower speeds? When accellerating from a stop sign does it get up and go strong and does the rpms go pretty high? Have you looked at the carb linkage? When you step on the gas pedal does it open the butterflys all the way?

The car does not get up and go. Runs fine once getting down the hwy. Continues to die at almost every stop. I plan to chk points, distributer, timing and also planning to use carb cleaner etc... tomorrow.

Running good

Cool, glad you found your problem. Often you need to back to the basics. Thats why ask certain questions before I say it's this! If your points will not allow your timing to advance, well, then your motor will only run to a certain point. It will run strong till then, however as your speed increases, so does the engines need to have more time to burn the same amount of fuel. Anyway, glad you figured it out, good for you. :eek:k3:

ltrrtl, Do your self a favor...HEI conversion, 600 CFM 4 bbl, dual exhaust. Less tune-up issues, more power, better MPG.

Assuming your 350 has the stock cam , a Holly 600 will do it good.
My engine having a slight upgrade cam runs poorly untile the engine warms up with the 600. Stalling is a problem for me for the first mile or two.
After that it's great !!!!!

holly vs. Edelbrock

Old Bones (all)

Yes, the 350 is all original... :yikes:

What are your thoughts on Holly 600 CFM vs. Edelbrock 600 CFM ?:dunno:

I have a 71 Chevy PU with a Edelbrock 600 CFM and I like the performance I am getting. (installing Headers on the Pick-up this weekend):yahoo:

I am considering staying with the Edelbrock so that I am consistent with my two classics.

thoughts?

Hey Bones, Sounds like you have choke issues. ltrrtl, I've had several of both, I like the Edelbrock because of the adjustabilty with very little mess. Being an old guy, I love Quadrajets, the spread-bore design really gives you the best of both worlds, good MPG when on the small front primary's, and a good kick when you open the big secondary's. But they aren't cheap & aren't the most user friendly to set-up right.

Installed HEI, new plug and wires. Also replaced old air cleaner with new open Edelbrock which removed old style heat riser setup. Only issue I am seeing is it takes longer to warm up. Seriously considering adding a Edelbrock 600 with electric chock. Thoughts?

im bummed i chimed in too late too push quadrajet shame on ya'll haha. would probly find the divorced choke setup to be extremely convenient i know i do. once its setup right it is just so streight forward. i woulda also said holleys have amazing throttle response but ive never been able to pull any better than 11 mpg out of one. im biased against afb style carbs so thats that on eb
