Re: what cam to use?
268 and no larger on a 110lsa would be right at home, maybe a tad too big but it will have a noticeable idle and pull well, def make power in a wide rpm range.
Btw, I had one in a 210/327 with milled heads, decked block, 4bbl, hei, intake, headers, and other stuff too lengthy to mention and it really liked it (manual trans and 3.08 rear, cant speak for auto). I guess it had 9:1 maybe 9.25:1 with the milling and decking...
