Brickies? Mick.

I had a metallic blue HK 307 auto 3.36 with 34000 miles when i was 21 yrs old ,it was rated at 210hp and it did 16.6 1/4 mile at Castlereagh which was a second faster than those dumb road testers,then i modified the engine and fitted a 4spd and did wheel spinning 14.7s .I remember calculating 220hp using the weight shifted hp formula which would be pretty close to rwhp.

Those were the days when a street meet was racing on a Sunday night not far from my place .

 

Remember though Mick the Press tests for a 307 GTS around October 1968 were for a fully loaded car (air and steer) and from memory a 2.78 rear axle (will check). And GMH purposely didn't have a 307 manual at the Surfers Paradise release, as that car would have showed what they were trying to hide a bit (the true potential of the GTS327). All Press 1/4 mile tests of the day were done with two people, and they throttle lifted at each gear change (on a manual). Your 14.7 from a modded 307 manual with 3.36 putting out approx. 220rwhp is a very good indication of the true 1/4 mile capability of a HT-HG GTS350 manual. The later HG version with the bigger port heads was good for about 207rwhp, had a 3.08 rear axle, weighs about the same and AMC Magazine pulled a 14.78 out of it with two people, 26 Gallons of fuel in the tank and throttle lifting at shifts. So pretty much shows a direct comparison between the cars.
