The 'Quickest' A-Body Small Blocks

I have the #7 car, as posted in other posts, bought it new in 1969, 340, 4 speed and 3:91 Sure Grip. It ran 14:50's at 99 mph. These times were run at Thunder Valley, Marion SD in the heat of summer of 1969 on E70 bias ply tires.

I have rebuilt the engine to mostly factory specs, a little less compression for pump gas, a Federal Mogul cam with very close specs to the '68 340 4 speed cam. The engine is blue printed and balanced using the original block, crank, rods, heads and intake. The AVS is a replacement but the correct one. I am using the factory exhaust manifolds. I have upgraded to a electronic ignition.

The cams in the '68 were hotter for the 4 speeds. The autos and 4 speeds in '69 shared the same cam, thus the '68 4 speeds were quicker.

The transmission is the same as it was in '69. I do have 3:55's with the Sure Grip in it now. I am changing to the 3:91's. The tires are radials the size equivilent of the E70's.

The car was ran with a "skinny" driver in 1969. It will go down the track with a "mature" driver now here shortly. It is going to be interesting to see if I can get close to the 14:50 times. That is my goal and that is why I build the engine the way I did and chose not to use headers.
