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.
Had a friend with a 70 340 4 speed Dart. It had a 77 360 with 474 cam ld340 intake and headers. It cranked 117-130 lbs 3.91 gears and it was dead till 3000 rpm and fell off at 6500. Lol
