I really like your car. I think it's about the toughest looking 73 I've ever seen. The wheels really set it off and the stance is perfect.

Loved the video's and love the car.

It's the Pypes 2 1/2" stainless X pipe using their Street Pro mufflers connected to Hooker ceramic Super Comp headers. Exhaust tips are Flowmaster 3" outlet.

Have not gotten any numbers yet but I believe HP and Torque in the low 400. I can say for sure 0 to 60 is quick and I have not really punched it hard. I am still breaking it all in and tweaking the EFI system to try to smooth the motor out some more. If I get 12 mpg on the freeway I will still be happy.

Have not taken the mpg drives yet but suspect @same. According to my man with the blueprinting plan back in a day when it is rebuilt @ 9.5 compression with solid lifters and HiPro 'Lunati' camshaft but tested on a Summit G-tech meter it did 60 @6 seconds then when I attempted the 1/4mile on an open road, panicked a little, forgot to take it out of first when I heard one hell of a backfire, pulled over, checked the meter, said 58 mph@7,200rpm's. Thank God for the solid lifter improvement. With a little checkup on the gaskets, next time will do it right, - on the track! Think with the Edelbrock 2 barrel intake manifold, to 3" Hookers, down to 2 1/4" pipes through the H-pipe and into a pair 2 1/4" Flowmaster 40's think would be wiser to refit an Edelbrock Air Gap 4 barrel intake manifold and from the Hookers, into a pair of 3" pipes through an x pipe, then into a pair of Flowmaster 10's. For now, here is my set up, from it bottom.

hey, would you mind measuring and telling me what height you have from the ground to your fender lip, just above your rear tires on your 73? What rear leafs do you have?...how many leafs?...standard eye?

Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic! thumb

PS-@ mufflers on the 2 1/4 is Flowmaster 40s. With 10 1/2 inch brake pad-power disc Summit in the front and SSBC conversion in the back- all the way around...not bad but with the aftermarket compressor, always rattling away...does not seem as good as the original pie plate that's on the Mach 1s from the factory. So what is size of your brake pads? Just had the power rear line locks(parking brake) rerouted inside the frame. A real hack job per my leg problems - had to have done up by this Mobility Works Company that does ....for those with handicap....however turned out to be a real 'hack' job. finally took it to where had a heavy duty clutch and the Cleveland reworked with the solid lifters at 9.5:1 compression in Greensburg, PA use to be a specialty race engine shop called Motor Works since, changed to new owners that also very reliable with from engine, turbos, carbs, intakes, brakes, .....did correction on brakes and installed an Edelbrock Performance Air Gap 4 barrel intake manifold to replace an Edelbrock 2 barrel intake manifold as what previous owner did when thinking he was able to get better gas mileage on a Cleveland. LOL only thingit did was shake the H out of the mustang w/in high torque at low miles per hour.
