On Steve's Nova Site (http://stevesnovasite.com/forums/showthread.php?t=19352) someone receive and posted GM of Canada paper work for a 1972 Nova SS. The paper work showed 350 cu. in. w/ 270 hp. Everything I have seen shows a ’72 Nova SS came with 200 hp. Was it standard for cars that were shipped out of the U.S. to have a higher horsepower rating?
I bet that is the difference between the "gross" HP and the "net" HP. 1972 was the year GM made the change to net numbers.

My guess is it has something to do with the conversion of English measure to the metric system. Canucks likely don't use foot pounds. Just a thought.

Don't take all the GM of Canada stuff as total gospel. While Larry Davidson was on the ball and was a car nut himself, some others weren't and some mistakes were made. An L78 Pontiac just about got the documentation sent out listing it as having a 375 hp 396. Our '72 Lemans has the L78 400. Perhaps I can get things juggled to read 396 375hp and have one of one. A COPO Pontiac even. Think of the possiblities. Everything else has been tried on E-bay. http://www.yenko.net/ubbthreads/images/graemlins/wink.gif

Metric system coversion was right at about that time, but i don't think that was the reason as it was a slow changeover.

I have a '72 brochure listing a 350 at 165 hp. This was a net rating. Our 400 Pontiac was rated at 250 hp with dual exhaust and 200 with single. The net ratings are a little closer to real world, as installed in the car.

I have a '72 brochure and the assembly manual that indicates 200hp for the Nova SS. Alan Colvin's book indicates 175 hp for the SS. http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif

Maybe so. What is the horsepower rating on your car? http://www.yenko.net/ubbthreads/images/graemlins/smile.gif

The HP rating on Joeys car is 50. At least he drives it like it is! http://www.yenko.net/ubbthreads/images/graemlins/tongue.gif http://www.yenko.net/ubbthreads/images/graemlins/grin.gif

The story behind frank and joe not having horsepower ratings on their cars came from the original owner car dad bought in NJ. That one didn't have it. Wasn't sure if that was something yenko did but I did it to both of their cars when we finished them. It would sound about right with the numbers that frank put up at the last reunion. lmao http://www.yenko.net/ubbthreads/images/graemlins/wink.gif

Yes, it was common for Yenko to trim the 360 HP rating off the air cleaner, I was just joking about it, although maybe mine said 50hp before the trimming. http://www.yenko.net/ubbthreads/images/graemlins/grin.gif Say...how many HP do you actually need to back out of the garage and pull back in? http://www.yenko.net/ubbthreads/images/graemlins/hmmm.gif
