This is a pic, provided to me by Tom Tate, of G & R’s first Pro Stock Maverick. Boss 429 Power. Lot’s of shaking out of the concept and the engine occurred on this vehicle.

Shot of the Boss 429 Mustang on the Track
Looks like a shakedown run. Have a bunch of other pics from the same day. I’m digging the big ‘Performance Engineering’ sign on the back.
Boss 429 Mustang – The jaws are open
I can’t let April 29th (4/29) pass without a post about the Boss 429 Mustang now can I?
Shot of the front of the Mustang flopper.
Pro Stock Boss 429 Maverick – Engine Compartment
Nice look at the engine compartment of the first Boss 429 Maverick. Bit of work to shoehorn that thing in there.
The Ultimate Boss 429
Not my words…though I agree.
Hi-Port Dual Spark Plug Boss 429
I post these images mostly because they are ‘What if’s?”
In the early 1970’s in Pro Stock the Hemi was engine to beat. As we know NHRA weight factoring changed that landscape. Before the refactoring G & R ran Boss 429 Maverick’s.
The cars were competitive but the Boss 429 was not a world-beater in Drag Racing.
Soooo….what do you do?
Experiment that’s what. These heads look have been developed by G & R to help solve the breathing problems that the 429 had and provide more spark to the fire.
So, if Jenkin’s had not lobbied NHRA for small-wheel base vehicles it look like the 429 might have advanced a lot faster.
Boss 429 Maverick
This is from a magazine article titled “Wayne Gapp Builds a Hi-Port-2-Plug-429”. I’ll post the article sometime soon.

Gapp Blasts 9.70 for Indy Pro Stock Win
INDIANAPOLIS RACEWAY PARK, Indiana – Gapp and Roush’s “Shotgun Express” Maverick had the Indy Pro Stock field covered, as Wayne Gapp clicked off times of 9.75, 9.76 and finally 9.82, 140.40 mph for the title. His 9.82 in the final round edged Greg Brenneman’s Duster.

A post about Barrett-Jackson, ‘Gate Job’ and a 1969 Mustang…
Here is a link to the Barrett Jackson web site.
The link is to the Pete Gate ‘Gate Job’ funny car. Sold for $176,000.00.
Why post something here about that vehicle? This car was purchased by my Dad back in the late 1960’s. He sold off the bits he didn’t want or need, had his Mustang body built and mounted on the chassis of this car.
Images of that vehicle, the 1969 Mustang, can be found elsewhere on this site.

Here’s a shot of the ’69 Mustang. Finished mechanically and waiting to get a bit more on the paint side of things.
