Finally got my 73 Mach 1 with the fresh 521 to the Dyno today with my car group. After changing jets on the Dyno 3 times i gained 50 horses just sitting there. My build is for monstrous Torque, but due to my gearing and torque converter, plus stock valves and cast iron heads with beehive springs and roller tip rockers the 68 Camaro sporting the 502 still beat me but he has been fine tuning his setup for quite some time.

Had a brand new 1350 driveline custom made for the car, and at the moment still have the stock open rear with 2.75:1 gears

I would have loved to run the engine on a dyno by itself but to save money the machine shop just put the long block together and did the machine work to the heads, and I brought it home in pieces and put it together myself as well as putting it into the car all in my garage. You can see my entire build thread from start to finish at this link.

http://www.7173mustangs.com/thread-my-intro-and-build-thread

I have alot of pictures on my thread there.

I plan on in the future upgrading to trick flow bare aluminum heads PowerPort® 325, take all my current hardware except for the valves and transfer them to these new heads with new valves, then go about 2 cam sizes up in size during the head swap. Then i plan on upgrading to the expensive comp full roller rockers instead of my cast roller tips i have now. I am also trying to find a good deal on a 31 spline posi trak lock pumpkin with 3:50 gears.

My buddy in the Camaro is the one who helped me build this engine and he said after the dyno runs that he was blown away i put out what i did with those stock cast iron DOVE heads, and thinks that doing the head upgrade will really wake my 521 up.

So i wonder what your setup will do at the tire on the dyno.

I don't know what mine will do at the tire.I know my headers that are going in the car won't be as good as the dyno headers.Im using FPA headers for ground clearance they are a shorty design.

Yeah, I had purchased the Crites full length headers pretty early then after having them for a while started seeing people posting how low they hang and hitting them on stuff. All in all I am very happy with the Crites headers. I purchased all new front suspension and steering and got the progressive big block springs brand new and after driving my setup since February I think I have scraped my v-band clamps 1 or 2 times going over a pretty big speed bump.

My engine wanted a little more carb,it was pulling more manifold vacuum than it should have at wot.Would make a bit more peak hp with a 1050.The 950 was custom built by Competition Carbs it has excellent throttle response and good street manners.They claim it's pretty efficient for what it is too.
