Right, I've a bit more time to give some info on how it drives. I've only driven it the once so far when I picked it up from Martin the other day, but hopefully I can test it soon & see what it does in dry conditions. The engine fires up first time from cold without using any throttle whatsoever. It probably just cranks 2-3 times & fires up. You need to tickle the throttle to keep it running as there are no chokes on the carbs. After a few moments it will sit & idle at 800 rpm. Once up to temperature, throttle response is instant!! It will comfortably cruise at 2-2500 rpm in 4th gear (55 mph) with just 1/4" of throttle movement. It was damp when I drove it home, but found that from 2500 rpm in 4th gear it could brake traction instantly if you stabbed the throttle. The car hasn't got underperforming American tyres, it has Avon ZZ3's, which have very good road holding charecteristics in all weathers as a rule. Admittedly the road was damp, but even with the single carb fitted it could brake traction in 3rd gear from those sort of RPM's in the dry if you nailed it, just ask Ray (camaro 78)
. Looking forward now to driving it in the dry. Thankfully we've a local race track/private old airfield, so I can see what it will really do without having other road users to contend with.
As you say, cams, technology etc have moved on, but as Martin said, you really wouldn't know what was under the hood unless you looked. It certainly didn't feel as if it's lost any of it's low down/mid range torque & it was certainly used to be very torquey with the single 4bbl on. If anything its made the engine feel "bigger" whilst increasing mid to high range power. Incidentally, the crossram powered '69 Camaro of Penske/Donohue was dynoed at an average of 440 hp & could run the 1/4 mile in the mid to low 12 second bracket.
Just gotta get a fine day now to get a feel for it .
