K Laz, I'd like to check it out. The hot setup back in The Day was a Sprite with a 289 in it because it was practically a bolt-in swap for the stock 4 cylinder motor-mount wise. Of course you still had to weld on the cross member and rear mounts, but it was a relatively easy swap and man o man those little Sprites were quick. Well, for The Day, anyway.
I don't know about fastest accelerating but the scariest accelerating I ever did was while backing down an extremely long and crowded launching ramp at Lake Oroville and having my breaks go soft on me. I was in a 74 Scout, manual transmission, and I was pumping that brake pedal like a hillbilly fiddle player on Meth while trying to jam it into any forward gear I could find. Got stopped right at the last moment, but had to endure the dirty looks from the other boaters who thought I'd backed down the ramp that fast on purpose.
Hblair, no troll, just sayin. You jogged the ol memory of cruising El Camino Blvd. back in The Day. The hot rods in 1967 might not have been as fast as the Hondas and Acuras are today, but they certainly looked and sounded faster, plus had more character.
