Need 318 help/advice

8.1 compression is a delicate animal when choosing a cam. Sometimes narrow lsa is good , idle is hype, and the sleeper is born...
If he advanced it 4 degrees and bumped the initial timing up to 18 or 22 degrees and limited the mechanical advance to 11-12 degrees for a total=32-34 degrees full advance by 2800rpm ..it would do burnouts, if that what he wants.
I recall wanting to run 360 heads on my 318 with that Summit cam, but stock with stock heads because I didn't want to lower compression. It was an interim engine until I got my 340 buttoned up.
