Man, those were the days. Downdraft carbs, engines bored out to bigger cubic inches, extra strong transmissions to handle the power as you raced down the strip.
Woo Hoo!I wish our kids had that these days.
A Holley Double Pumper with two fuel lines. 650 to 1150 cfm. You had to be running a lot of revs to keep the thing from strangling on the fuel. 4.11 rear end, valve springs so tight to slam them closed fast nothing would hold them in place.
The Quadrajets had two fuel dump jets. A secondary spring picked them up when you romped on the gas and just dumped gasoline into the intake from a reservoir until the vacuum could pick up.
I tuned almost every Saturday and cleaned spark plugs, filed points, set advance springs.
I learned about engineering from vendor catalogs. They were chock full of rules of thumb, nomographs and formulae.
I remember one late summer night coming through the mountains and a long banked curve, a full tank of 18 cent gasoline, a new pickup, a blonde farm girl and KVOO on the radio. Life has never been any better than that. It was the height of Nam, we young men were anxious but we had FREEDOM!
I married the girl and still have the pickup and her.
