Tom S,
Unless the Chevy guys know how to change the basic
Torque/Hp engineering relationship Hp and Torque
will ALWAYS cross at 5250 rpm.
The fact that his Torque falls off and crosses the HP line around 4800 tells me the dyno run was
corrupted. Apparently he bought the powertrain from the Detroit Speed people and they never bothered to tell him that relationship. After all
both owners are former suspension engineers from
GM and probably do not deal with engines much.
He has a beautifully constructed GTO with all the
latest driveline and suspension/brake mods. Drool
everytime I read about the car.
Item TWO:
Been around BB Chevy guys for years. Friend had a
64 GTO with 396 "375" engine. Ran 11.70s in mid
70s. Rectangular port engine. A friend named Ralph Piper had a 66 tempest in the same time period with a 455 that would run 11.55 et.
Another friend had 66 chevelle with 427 L-88 heads
and crash box built with tunnel ram and 660s.
Would run 10.70s at 129.
Quite a few pontiacs today will run those times
with one 4 barrel. Maybe not the mph though.
Real advantage to Big Chevy crate motors is they are cheap, same for SB chevy stuff, Has been that
way for years. Pontiacs can be made to run as fast.
Item Three:
Quote"
The Pontiac is the best engine ever designed and has yet to reach its development peak"
Steve, that is a REAL STRETCH even for you to say.
Most engineers would say the Formula 1 engines out there right now are the best. Air craft types
would say the "Griffin" or Merlin" engines would
be the best.
I will say the Pontiac was one of the most
"Modular" engines ever created. Even better than the SB Chevy. Tom V.
