Fastest 71-73 mustang belonging to forum member

[Tyson Blair]

Hello gentlemen,
I hit 140mph in my 71 the other day and I got to wandering what is the fastest top speed you guys have pushed your machines to. I know 140 is no big deal. It would be cool to see a 71-73 built for speed. Mine is a mild 429 with 3.0 gears and a c6. Probably tops out at 5500 rpm. What top speeds have you guys hit and what modifications if any did you make?

I'll tell you what isn't the fastest Mustang in the group... mine! It runs out of horsepower at 98 MPH indicated. Boo-hoo!!!

Mine has done 129 in the quarter. Around 10.9 seconds.

Hasn't someone loaded his car onto a plane for a cross-country or cross-ocean flight? There, the speeds would be around 650 mph!

Good 1 ML!
My ragtop at 120 is enuff for me on a short stretch of Interstate here in WI. She wants to keep pulling but with no “feel on the wheel” it’s time to stop being a dumber ass.

I agree. Steering feel gets downright spooky. I took my XJS v12 to 140 with finger tips only on the wheel. Not anymore. My 73 302 would be lucky to hit 100.

This is common theme. The power steering feel is definitely of the one finger on the wheel overassisted type. It is fitting for a Lincoln but it is not confidence inspiring on a mustang at speed.

What is an XJS a jaguar?
Love v12s only drove one once on track in Las Vegas. It was an Aston Martin. Driving a NA engine that revs to 9000rpm is amazing

Aston Martins do not have north American engines if I'm reading you right.
Earlier Aston's used Jaguar engines up to 2005, then switched to Merc and are still using Merc engines, the M117 I believe.
The XJS Jaguar was from 1975 to I think 1996. That was one beautiful engine, but a bi*ch to keep tuned.

It has a 351 Cleveland that has been dynoed at 750 at the rear wheels. A big bore 6-71 blower really helps. lol
