All manufacturer HP numbers are at the crank. I don't know the exact differences between how the net and gross numbers were achieved but SAE net forced the manufacturer to dyno the engine in a configuration much closer to how it would be installed in the car while SAE gross allowed for many of the popular "free HP" tricks to be used like straight piped exhausts, no air filter and leaving the FEAD off as you mentioned. I have my doubts about the oil pump being bypassed but have no proof so...AFAIK, SAE 'gross' was used prior to 1972..and SAE 'net' was used after 1972. The SAE 'gross' hp numbers were measured at the engine, not the rear wheels..... and did not include anything driven by the fead belt..and think it may also have not included the oil pump...(driven by the crank, and internal).
The owner of the Shell station I worked at in high school ‘78-‘82 had a ‘63 split window vette with the rear spring set up you describe. Had 350 LT-1 in it with factory side pipes and Shell 78 series radials all the way around 12.8 1/4 all day long. The mechanics there had a ‘67 Malibu w/ L-88 vette motor in it open headers,slicks, 4:88 rear 10.7 1/4 all day long. Those were the days!AFAIK, SAE 'gross' was used prior to 1972..and SAE 'net' was used after 1972.

I think on the big hemi engine, that AC was not an available option..no room for it. Some of the popular magazines at the time (68-72) said the 440 would beat the 426 hemi in a street race, ( light to light).
A few years ago, at a gas station way out of town, this fellow had just bought an old vette..and it was up on a flatbed. Viewed from the rear, it had a single leaf spring going across the back, from left to right wtf ? That was a new one for me.
And my Opel has a transverse FRONT leafspring...doesn't that look fun?A few years ago, at a gas station way out of town, this fellow had just bought an old vette..and it was up on a flatbed.

How fast were they and how much power did they really have?
Take a look at the attached file and let's start a discussion.
Ah yes.....the old Pontiac Super Duty 455 V8's.......I am old Pontiac guy
Thanks. I love black with red interior as well!The only Impala I like is a 61 bubble top. Especially in black, red spear and interior, with aluminum slots.
I like the patina on the Plymouth, as well. Safe to park at the grocery store!
