This isn"t your reg truck cam ???? Cam guys -->
Just looking for some insite here.. This cam is not for my truck, it is for my GM powered dodge 
.. Ran some numbers with a cam guy,with the info I just provided, this is the specs he said will work with my set up.. Is it me or does the lift seem a little low?? Any insite is great. Hydro roller cam.. I will also be contacting a few other people to see if this will make the power with what I have..
Car weights 3200
4.30 gear
31'' tires(rear)
Turbo 400 with 3400 converter
Engine is a 383'' topped with a 8-71, shooting for 900 hp( yes it can be done, the bottom end is no joke)
Heads are Dart Pro 1
230 cc runners
2.08 intake 1.98 exhaust
72cc chambers.
Cam that the guy at cam place spec'd
This is on 050
.541 intake .541 exhaust 113 lsa( said I wanted some chop) 110 center line
Intake dur 240 exhaust is 250..
What ya think??

I figure your running sbc.So imo no the lift numbers do not seem low conservetive yes but,not too low.Most cams are speced off 1.5rr 1.6's put you bout .575" so thats not out of the ordinary.In any matter no real need for a ton of lift.Its really not gonna be a big factor in that setup.Now too high lift on the other hand could cost you big real fast.SBC Is a way diffrent animal to build than the ls design.

Totally understand. But with the heads that is on it, seems like lift should be higher, even if it is getting stuffed in the ting. Yes that was speced with 1.5 rockers..

I just got a cam spec'd for my Camaro by Pat G. It has a 377 with Dart Pro 1 heads and all the other goodies. Unfortunately, I don't know anything about PTV clearance, head gasket thickness, deck height, etc. So Pat spec'd the lift a bit conservative(236/242, .585/.540, 109lsa).
Perhaps the lift is low to keep the valves away from the pistons with all that duration???

I have a flat tappet 260/266 @ .050 .559/.549 106 lsa cam in my sbc dirt track motor. With proline 220 cc heads it made 453rwhp.
Those lift numbers are in the ballpark for a hydraulic or solid flat tappet cam. But if your solid roller those numbers are very low.
