Lately I have been asking for some input on cams and such for my 68 Torino w/460 .030 over. The cam was unanimously considered the MAJOR downfall of my engine combo. Barely larger than stock, 471 lift, hydraulic flat tappet while rest of it was forged dished pistons with valve reliefs, steel crank double keyed for blower and HD ford rods. Energizer roller rockers pushing stock springs. Heads had Manley race duty valves oversized and as far as I could tell the ports had been worked. 6-71 blower pushing 5-7 lbs boost @ 10% under, dual 750 doms.
The rest of the car is full tube chassis, alum interior, full double dragster roll cage, P/G trans w/brake, 9" with strange everything and 33" slicks. Weight was 3,200 without me.
Problem was, no matter how good it wanted to light the tires or how fast it would rev. It left the line like a dog with an even 12 sec pass being its best after 7 passes. Note: I bought the car as it was and it had never been on the road, let alone the track.
So here is the new set up and you can see some before and after pics on my profile page. Until I learn how to post them on here.
