Post SBC Timing--Overheating???

I have a sbc that runs hot in slow moving traffic. Timing is set at 10 degrees BTDC. Talked to supplier today at swap meet and he suggested running as much advance as possible until pinging starts???? What kind of timing are you guys running??? Any comments appreciated DAVE SHANK

Doesn't sound timming to me, Sounds like a restriction in air flow through the radiater. We need more info from you.

I agree with johnsongrass1.

When the car is warmed up, feel around the surface of the radiator for cold spots. If you find one your radiator is plugged.

Radiator is aluminum, 16 inch flex fan plus electric pusher. All is okay until air flow slows down in traffic. Headers putting out a lot of heat but don't glow red. I know timing is important but how will that effect overall engine temperature??? What timimg are you guys running on SBC???

Do you have a vaccum advance? Is it hooked up? Where is it hooked?

I run 34 degrees Total advance at 2500 rpms.

I think it is a combination of things but timing definately does have an effect. My poncho 428 was running hot at idle and I fine tuned the carb and the timing and it helped a lot. It will still get a little hot if I let it idle to long. I have an electric and mechanical fan and new core in the rad. I am looking for a shroud which I think will completely solve the problem.

You really should not need both the flex fan and the electric pusher to cool your engine with a properly sized aluminum radiator. Pusher fans are not as efficient as a puller. Depending on your vehicle; you may need to install a fan shroud. As to the timing. I run mine at 36 degrees total advance with the vacuum line disconnected and plugged. I do reconnect the vacuum line after setting the timing. I also have the vacuum line on full vacuum rather than the ported connection. Works best for me that way. Idle is set at 700 RPM in gear. I have a 1928 Ford running a Walker 4-row radiator, 16# cap, 180 degree thermostat, 16" puller electric fan and no shroud. The fan is centered in the radiator finned area. Runs a constant 180-185 in all kinds of traffic and air temperatures. The fan runs all the time when the ignition switch is turned on. The engine is a 350 Chevy small block, AFR 190cc aluminum heads, Comp 280H magnum cam, Edelbrock Air Gap intake, Holley 770cfm Street Avenger, blockhugger headers and HEI ignition. TCI Saturday Night Special (1800-2200 stall), 350th trans and 8" Ford rear with 3.80-1 gearing.
