With 250 hp in a 2750 lb. truck you're looking at about 11 lbs per hp. Not quite a GT 500, but not to shabby either. Should really get up and go. :thumbsup:
Wish my memory was better. In 1961 I had a 55 business coupe with a 292 in it. It ran 18's at 78-80 mph stock with a 2 barrel.
By the time I finished with it in 1965, I was running 14 flat at just over 100 mph. Of course I was running 6, 2 barrel carbs.
A cam with 505 lift and something like 290 deg duration with all kinds of overlap. It had pop up pistons with about 14.-14.5:1 C/R.
It was very finicky about gas and wouldn't run worth a darn on anything less than Amaco hi-test or Sunoco 260
It didn't idle much below 17-1800 rpm and even then it was ruff as heck. But WOW: what a top end. I was shifting at 73-7500 rpm.
All the Chevy guys thought I was B.S.ing them when I told them that. Said no Y-block could get that high. :thumbsup:
I laughed all the way to the trophy stand.
