"It's not really radical," he says. "It settled the car down on the street and made it work better on the track. He did a great job." Ron decided the specs were on a need-to-know basis, and, frankly, nobody needs to know.
Behind the motor is a 727 full of good stuff from Cope Racing Transmissions, cranking gears off with a B&M Quicksilver shifter though a Griner valvebody. The Dana 60 out back sports Moser hardware and a barely streetable 4.30 gear set.
The final note of interest would be the suspension. Ron pulled the leaf springs and went with coilover QA-1 shocks and a ladder bar setup that allows the suspension some adjustability on the racetrack. Factory front disc and aftermarket Wilwood rear brakes slow it down, while the stock interior is augmented by lightweight buckets, a Grant steering wheel, G-Force belts, and Auto meter gauging.
So, how fast does it go? Ron and fellow Marine/crew member Luke Dowd tweaked on it at the Mopars at the Rock show to get a fat 10.23 at 132 mph.
