Power difference between these 2 cams?
This is what I have now,it has more power than the stock one but doesn't seem big enough on the specs.
Dur deg. @ .050
int. 220 exh. 220
Valve lift .431 .431
What would the power difference be if I switch to the trd level 1 cam
intake lift 0.416"
exhaust lift 0.430"
intake dur 262
exhaust dur 272
dur @.050 214/224

i THINK that w/ the longer duration and less lift you will have more at the top end vs. more lift and less duration which will yield more torque. which seems like what you are after. it seems like going to the trd will yield a bit more overall performance, based uopn the specs. not a 100% though.

My power is more on the top end now.I am still running stock 4.10 gears and it has more get up after the engine build but not what I was expecting.Once it hits 2500-4500 rpms it screams like a race truck but I live in the mountains and need some on the lower end.

Funny, we have fairly similar settups adn I went through the same thing. I had a LCE Pro EFI in there and the sucker flat out moved past 3000 but was a dog til then. I switched to engnbldr's smaller cam (sorry will have to check specs tonight at home) and it was a good improvement but now just has mild to good power across the board.
I'll check my specs and see what I can tell ya.

alright, here we go:
old high end cam:
Intake lift = .430
Exhaust lift = .444
Intake Duration = 272
Exhaust Duration = 282
Duration @ .050 lift = 224/234
Advertsed RPM range = 1600-5700
New cam is the 261c and of course, my specs for that one is at work...
