Thread: Need carb/ignition tuning advice.

Tweet

Hello everyone,

This is my first post (obviously) I need some advice on getting my car to run right. About 4 years ago, I put a Recon reman 350 in my camaro, and all the stuff you see in my sig. I've got it to idle and run alright, but it's lacking power a little.

No, I don't expect a 13 second car with my current setup, but I'd love to see the mid-high 14's.

The engine internals are completely stock. Stock cam also. I do not know the compression ratio either.

It was bogging badly when I dropped the throttle, and then it would pick up great. But it's always breaking up around 4,000-4,500 rpm.

With my current timing advance: 18 deg. BTDC and the carb setup as it is (I did change the jets and metering rods), it still bogs (not as bad), but the high rpm break-up is still there.

Anyone know what I can do to get the most out of my setup?

Thanks!

EDIT: Last summer I ran a best of 15.33 @ 90.81mph

They seem to be the right heat range, as i get no detonation, and when I changed them (for the hell of it) they were a nice light brown. The plug wires are brand new. The car runs fine under normal conditions, but when I get on it is when the problems show up.

The plugs were gapped .035 i think, and they were not damaged at all. I changed them about 1500 miles ago. With no performance difference.

I never checked the spark. Now that you mention it, I'm using my stock HEI coil from the 305. I'll replace that (been meaning to anyway) And the valve springs on that motor are said to be "remanufactured." Now I don't know how they'd reman valve springs, but I'll look into replacing them this summer as well.

Thanks!
