MacNeish runs 10.40's with his D/S 302 camaro. Not sure what NHRA rates them now but a 302/290 hp motor I think is NHRA rated at 310 or so? Don't hold me to that but close I think. That NHRA rating kinda hurts them.
Everything has to work perfect and there are many tricks to the trade that they ALL do. Gearing is a big part along with the clutch and even the correct headers. When the 1985 versions of the 305 camaros run in the 10's you know the HP rating from GM is way off. NHRA adds HP to those figures. |

The headers are one point I didn't consider. Maybe the ones used in the car weren't the ones used on the dyno??

Love the little small blocks, I use to watch a 289 65 Stang run at Norwalk years ago...... Unfrickinbelieveable! Serious RPM, 4sp and a untubbed rear. HP? Never knew never cared. It was a treat to see this car launch at what seemed like 6K + and head wheels up for a low 11.0 sec run. I hear it's still running, quicker but nowhere near as "stock appearing" as it was. A lot of little small blocks kicked some serious butt before the "good blocks" came out.

I bet Wade's Chevelle has a torque convertor about the size of a Burger King Whopper . . . .

I always fantasized about using a small centrifugal clutch in front of an automatic transmission instead of using a converter. Maybe have it work sorta like a snowmobile. Sometimes thinking like that, with enough time and money for testing and experimenting, might produce a winning race car. But then again, it could just be another Money Pit.

We ran a multiple disc clutch Powerglide with air shift in the Pro Nitrous Camaro , ran 1.10 60 foot times ..
Upgraded to 350 Turbo style with clutched torque converter & air.. ($30k + service/maintenance)...runs .960 60 ft times....nearly the best in class. And 3.70 et's @ 200 with soft tune ups. Brother Joe will Not tune it for KILL Mode to run 3.60's.....He's Never Lost a Motor ($150k + service/maintenance) in 4+ years of PDRA /ADRL Pro Nitrous Racing.

https://www.youtube.com/watch?v=QtSSMSDHysw </div></div> In modern NHRA STOCK CLASS, 302 & 305 Heads are so exotic that the valves are relocated, cantilevered and the heads cut in 1/4's , relocated & raised ports, rewelded etc, etc, etc......its common to have $18 - $ 22,000 + in heads and intake work.
