Re: 68 F100 Upgrade suggestions

Is the 390 cfm adequate or is a larger carb more in line with the flow of the new head? The ported big valve head with the larger street cam will need a 600 cfm carb. Gramps agrees with 'Doc' Muller. 600 vacuum secondaries is the way to go. You can also gain a few ponies going the tube header route...

A new JR head has small 66 cc chamber. The recommended off the shelf cams should have a .050" duration in the 220* range and an advertised duration of 280* or more. With that as a given the range of compression ratios are from 9:1 to 9.5:1 with pump gas octane from 87 to 93 respectively. Cams ...

You can lighten the pistons without taking weight off the crank - and vice-versa - just be sure all weights of the piston are the same, and the crank is rebalanced.
