2 1/2in exhaust manifold for small block Chevelle
There was never such a thing as a log style 2 1/2in ex manifold for Chevelles with a small block, correct???
In Alan Colvin's CHEVROLET by the numbers, 60-64, pg 160, there is a GM engineering drawing of a LEFT side ex manifold that supposedly has a 2.5in outlet, casting number 3840715. It is shown to be used on 64(ONLY) 300-365hp/327 engines---------------and supposedly the 365hp/327 was not installed in 64 or 65 Chevelles.
He states that it is very rare. I have never known of such a manifold, but after seeing this information in his book, I'm not ready to dispute it's existence.
No Right side is shown in his book.
Soooooooo, here is my question, has anyone seen, does anyone have, OR, does anyone know of the existence of such a manifold, left, and/or right side???
