A teen with 0.030" 9:1 KB pistons and a light wrist pin and 'WORKED' 273 rods, we re-balanced a stock 273 forged crank and removed over 3 pounds, 4 pounds before they added mallory metal.
Then mild ported 273 heads with 1.88/1.60 Manley small stem valves, a 272 cam, a Wiand Stealth and 625 AFB. A body 340 exh into a Flowmaster Y and 3" run back over the axle, it was real quite.
We were in the 12's in a 66 Vailant Wagon, 8 3/4 and 3.55 SG.
A rolling 20 MPH launch was brutal to many BBC guys.
We had all the parts on hand except the pistons, wrist pins and cam. Pistons were on sale so cheap.
