I have a 408, not sure if that is classified as a small or big block, it is a big small block, lol
Distributor in the back, small block regardless of cubes. Distributor in the front is big block. This is generally speaking for A, LA, B, and RB engines.
I have an EGT gauge, but don't know what the readings should be. I have TTI 3 step headers, 10:1 compress. and a pretty good cam, not the biggest, Eddy RPM heads. I need to know what normal, cool, and hot readings are. The sensor is located about 2 to 2-1/2 inches from the exhaust port, or header flange on the pass rear cylinder, should be 8 if I remember my cyl #'s correctly. If I need to post in Big Blocks, please just let me know.
Thanks
