part # 60412 thinking about going with this cam in a 408 motor. The car will have a 2500 stall 3.55 rearend.
Will this cam make alot of Tq early? I'm south of Houston so I need a A/C car what are yalls thoughts?

You could copy and paste the specs if you don't feel like typing.;-)

do you like your cam? what motor do you have?

Should have plenty of manners........not a ton of duration and lift.
I'm actually surprised that this is a roller grind.....I bet it really pops the valves open in a hurry.
What's the LSA ?
If it is 106 ish , it would be a stump puller.

 

[bentman]

LSA/ICL: 110/106 why would you be surprised that this is a roller cam?

Because those are hydraulic flat tappet like numbers.
Unless they are very quick ramps , it is gross overkill to see moderate lift and duration numbers like this in a roller.
Is it a hydraulic roller ?
That would make more sense.
I am not slamming the grind at all......but I tend to think that mild solid rollers start around .400 lobe lift and 240ish @ .050 and get pretty extreme from there.

What AC compressor are you running? That is something to consider. I believe the stock unit doesn't like to see more than about 5,500 RPM very often.

it is a vintage air and yes it is a hydra roller
