318 combo's

Here's mine, was originally built nearly 20 years ago, only recently got it running again:

318 block + 0.040", stock crank
Stock replacement pistons
318 heads plus 360 valves and some mild port work allegedly
stock pressed steel rocker gear
MP windage tray
Old Weiand high rise dual plain manifold, spread bore pattern
650 DP Holley (spread bore)
Home built shorty headers into dual 2.5" exhaust
Aussie Borg Warner 4 speed manual
4.44 gears 25.5" tyres

14.2 seconds @ 100.8 mph

The trick is 2900 lbs with the driver installed. Really needs some taller gears because it's running out of revs well before the end of the track.
