I used 351W pocket poted / gasket matched 1.85/1.55 valves for a few years and they worked very well. I changed to pocket ported / gasket matched TFTW Al. heads and maybe picked up 30-35 HP. Cost was about $2000 including 1.7 RR's, new push rods, gaskets, supplies, etc.

3.25 / 1 axle ratio is about right for the C-4 (no O.D.) on a street driven car . I turn 3000 rpm at 70 mph on the freeway and don't want to buzz more. Good low end torque and a moderate stall convertor (2500-2800) will still launch O.K. with the C-4.

A roller conversion hydraulic cam is best for all round use. I use a CC 268 flat tappet for my car, but would use an Extreme Energy dual profile hydraulic roller if doing it all again. Don't get too wild on the duration if you want good low end and street performance.

OK, I'll shut up now.
