Hmm Many Good ideas there Dan. The Boat guys told me to use the Chevy
327 Hipo rods which were plentifull, and very strong, because the stock rods
were cast iron. I have since found out that there are several length to the
"Stock" chev 327 rods..On the Sunbeam Tiger List, there has been a long
discussion of rod length's and their dis / advantages. It seems that the
longer rods are a better way to go. With Custom Pistons, the pin's
placement & offset are all variables to be determined.
No, the boat guys made no mention about the oiling, but in ALL other
engines that I have built, car and motorcycle for perfomance, I have alsways
reworked the oiling system. The oil journals were going to be cleared and
enlarged throughout the block and heads, along with a high volume pump with
higher presure relief valve and dual high flow filters and cooler with
thermostat. Larger vavles are better for breathing, but typically weigh
more and that becomes critical at high R's. I currently have a full set of
brand new TRW stock valves for the 63 215. My plan was to get some Manley
SS valves if the exist, or have them make a set for me.
Why should I source the roller rockers from Aussie land? Are they made
there? This is news to me!
Thanks Rich
