Looking for advice on approximate cylinder head intake/exhaust flow reccomendations for my build:
340 block .40 over, 4.00 crank, 11:1@65cc pistons,
[email protected] solid flat tappet, victor 340 intake, worked 950 Holley.
Going into factory weight '71 Demon w/ss leafs, 4:30 gears, reverse manual auto.
Considering...
1. Promaxx cnc: 285/195
2. Brodix cnc: 300/204
but some experienced advice before buying anything would be great.
Thanks
