I got a question for all of you
here the engine setup
289 C code 66
4bbl holley carb
.040 over
headers
and 2.5" pipes all the way out
whats would yall think the estimated HP is im think around 206-212rwhp
if anyone has a dyno sheet with a similar setup that would be appreciated.

 

Horsepower was measured quite differently back in 66. A stock C code was rated at 200hp, but in today's measurements, would be about 140hp at the rear wheels. The modifications will add 20-30 hp, I would guess. My guess is 170rwhp if everything is tuned properly.

 

That's prolly a little high. I know in 1965-66 the C code was rated at 200hp.

Commonly thought that an auto trans equipped car may lose 20% due to frictional losses - 160 hp at rear wheels. I don't think the Holley and headers would make up that much.

 

yea, reviewed horsepower a bit more. 20% loss when you go to SAE net horsepower in 1972, so the 200 advertised horsepower turns into 160hp (at the flywheel). Another 18-20% drivetrain loss to get to the wheels puts it at 128rwhp. Then you add the mods.

 

got more info on it

has a "racing cam" whatever that is and here is a dyno i found of a guy that has the "same" mods as what i asked.

For $50, you can get your own dyno sheet.

LOL i dont need one, not yet im about to do another motor swap with the next 6onths to a lot more power than i need, but need and wanting is completely diffrent

 

I had a 3/4 racing cam once.....I think they called it that because I raced that car about 3/4 of the time.

 

His car also appears to have a high rise aluminum intake and has a manual trans which will also make a difference in rear wheel hp.

 

"I had a 3/4 racing cam once.....I think they called it that because I raced that car about 3/4 of the time."
LOL nice the way the car is supposed to be ran


...you can tell all that from the dyn sheet?

Nope, from the pics of his car : http://home.nc.rr.com/hot67ponypage
