272-282 238-248 .485 .503 112LSA Use lunati 73943 @1.70"
just a little tamer but still a barrel of fun.
Shift it around 6700 rpm or so.
Ditch the powerglide trans. Its going to be lame behind a 307.
Get a th350 and 10" 3500 high stall.
so the .485/.503 wont b 2 big of a cam. the other member was saying if its over a certain amount the valves will hit etc. and will 3.73 gears b okay?
i kno nothing and i mean nothing about this stall converter thing. i know nothing about what it is or does??
