wondering about hp of a 75 camaro
 

going to go look at a 75 camaro with a 327 with a mild cam, dart heads, hydrolic rocker rollers, holly double pumper, and a new 350 tranny for 6k was wondering about how much hp could this car make?

Depends on more specific info. Hard to say with the info provided. I'd need specs on the "mild cam", and also what piston style in the engine, and which version of Dart head it is. Cam lift and duration, plus CR, and head runner and chamber volume, all add into the equation.

honestly i dont know guy im buying from didnt build the motor owner before him built it so ig no way of knowing hp unless i put it on a dyno

Write a bunch of different numbers down on small slips of paper, ranging between 250 and 400. Tape them to the wall, close your eyes, and throw a dart at the wall. Good luck, and let us know what your h.p. guess comes out to be. lol
Seriously tho, without knowing everything about how the engine was built, there's no way to figure what you have. If you have to know, dyno it.

just hoping for over 300 so its quick

I'm thinking you have to be at least 300, maybe more. Chevy was able to get up to 375 hp out of the 327 back in the day. The Dart heads, are they iron or aluminum?

i havent got a chance to see the car in person yet i been talking to the seller and idk there made of but it does have a electric fuel pump if that means anything

from pics and what he told me sounds to be set up good has big looks like 4 core rad and a electric fan on it

got a 79 instead with 383 stroker has 5 inches of paper work dynoed at 220 at the wheels idk if thats good or not?

Surprisingly low for a 383 stroker. Wonder why it wouldn't be at least 100 hp more RWHP?
