I just got my 1970 Mach 1 running last spring. My Mustang club was doing a Dyno Day, so I brought my car just for fun. We had just over ten cars from the club. This is was a wheel dyno, so the numbers weren't that high.
My Mustang won the "Pony Power" award for the highest horsepower from the carbureted car. The numbers don't appear very impressive, but they were much higher than the other cars. Two of the 289-powered cars didn't break 200 HP and won was at 204 HP. The last carb car to go was a '68 GT with a factory 390 and an Edelbrock top end kit. I expected that car to blow me out of the water. Although the torque numbers were higher than my car, the horsepower was well below. (I think he had some tuning issues.)
Here's a link to a video of the run just for fun.
My engine isn't at all tricked out. Here are some details in case you're curious:
- Factory 351 Cleveland short block
- Australian 2V Cleveland heads (iron)
- Custom solid, flat tappet cam from Bullet Cams
- Edelbrock Performer intake
- Summit Racing 600 CFM carb
- Factory distributor calibrated by Dan at Mustang Barn with Petronix III ignition
- Sanderson shorty headers
I don't know much about dyno numbers. I'm posting a copy of the graph and would appreciate comments.
