I was working at the local Chevy dealer (HS auto shop work experience) when their 1st 1967 Z28 rolled off the trailer. The UAW guys couldn't figure out how to install the Hurst shifter so I was tasked with fixing it. The trans/rearend guy I was working with told me to take it for a "good" test drive. Since school was just getting out that is where I took it to do some burnouts. When I got back the tuneup guy stuck it on the chassis dyno they had and he guestimated it was making 430+ hp at the crank.
That was the same engine design Chevy used for the whole series. After 67 Ford was playing catchup. The TP heads might have worked if Ford had let Shelby build the engines but the UAW guys didn't have the necessary tools/skills/parts to do it right. The cloned big block Chevy heads on the 302 did work but too many other problems beset the teams.
Penske perfected his wheel changing on pitstops when he changed the Javelins to 4 lug wheels - 20% less time tightening lugnuts - can anyone say "Unfair Advantage"?
Don't you mean 330 hp? This is from a write up about Tom's car on the Historic Trans AM website:
This first-generation Camaro Z-28 looks surprisingly stock except for the small front and rear spoilers. However, they had excellent underpinnings from the factory and could be turned into extremely competitive racing cars.
With huge intake and exhaust valves, the 302 V8 had potential for lots of power, and with the most careful assembly and blueprinting, as much as 440 bhp could be produced.
I know Tom pretty good also. We had our picture in an issue of Autoweek back in March of 1988
