There is a great yahoo site for the poly which I belong to. http://autos.groups.yahoo.com/group/318poly/ She's quite the engine, a step down when they changed blocks. I'm stroking my '64 poly to 402" with a six-pak and TTI headers.

I won't claim to be an expert on 318s, but it is my understanding that the common modern nickname for the early 318 is "wide block". The early 318 is really an "A" series small block engine (277, 301, 303, 318, 326) used from 1956 to 1967 (or 1966?). The heads were of the Poly design. This 318 was replaced by the "LA" (Late A) series engines (273, 318, 340, 360) with wedge design heads. My guess is that the bare blocks are very close in width, because they can interchange some major components such as cranks. The early heads were wider than the LA design, thus the "wide block" label was invented after the narrower LA design was introduced. ************************************************************* To unsubscribe or set your subscription options, please go to http://lists.psu.edu/cgi-bin/wa?SUBED1=l-forwardlook&A=1
