Sr and I finally got our Mach 1 back on the road. Previously had a worked over 302 boss engine that was chipped at 8k with 513’s. Was set up perfect. Currently has a freshly stroked 351/408 with a ton of torque and 355 gears 4 speed top loader. 235/60/15 tires - less power steering.

Want the best tires possible!!! Any advice? Currently it roast the tires all the way through 4 and have your hands full trying to keep it in one lane. Almost wish we would’ve went 323 gears but not really wanting to run the car much past 110. Engine is incredibly strong. Valako heads etc.

Kind of a neat story behind the two cars. I had the 73 z in high school (mid 80’s) and he had the Mach 1. Bunch of fun times and have had both (for the most part) ever since. So many times I hear omg I wish I would’ve kept… stories.

Are you planning on keeping the 15" wheels?? If so, that will limit choices.

I can tell you a 29" tall tire with 4.56's runs just under 110mph at 6000rpms.

Agreed, most of the performance compounds an Z rated tires are going to be in the bigger rim sizes.. Coker tire has made some that will cross over. depending on your driving style and intent, I have firestone pie cut street slicks on my 55 gasser. not good in rain, but it doesnt have wipers either.

What hp does the engine make?

Any suspension modifications?

Good hearing from you and hope all is well. I’d say an honest 550 + - @ 6,700. Ben at precision offshore built it years ago when he worked for Valako. Then was stored til recent. Solid Roller / j302 heads with all the good guy stuff.

I talked to Ben and he begged me to bring the engine down to dyno at his shop free of charge.

A beautiful car for sure...both, actually. But I've always loved that Mach 1...

How many miles a year do you drive the car?
