Help I have a problem.
Small block Chevy bored to 355. I don't know what brand pistons. The most vacumn I can pull from the cam is about 8-10 in. I don't know what brand cam or any specs. With timing set at about 16 degrees distributor (has no vacumn advance but does have a mechanical advance of about 10 degrees when accel). Has 1406 Eldebrock carb. With air/fuel mixture screws off seated 2 full turns the headers get bright red/orange from running so hot. Walker 3 core radiator with Cooling Components shroud
Any and all suggestions of a direction for me to go in would be greatly appreciated.
Thanks in advance guys.

Reason I don't have more information about the motor it was in car when I got it.
