Hey Guys, just throwing this idea around.
What types of cams would you like to see in a 5.3L engine on an engine dyno?
I'd like to start the mild cam at 212 with a low .500 lift and I'm open for any suggestions for the most aggressive cam.
Any input guys?
thanks,
allen

i take it this is for baseline Horsepower increases? Great Idea. It would be nice to know what a paticular cam with a basic tune across the board can yield power wise. I smell a magazine article!

I'd like to see the same lift and duration with different LSAs. 112, 114, 116 and 118 LSA

Is it possible to start with something like the Z06 and work up, its like 204/218 or somethin in that area.

i'd like to see some dyno runs on a tsp220/220 581/581 112lsa
going to be my future cam for the 5.3 while i get the 408 built..
how about the 212 218 low lift vs. 212 218 high lift, then the 220 220 114 vs. 220 220 112
then work up to the bigger cams 222 224 vs. 224 224 vs. 226 226
how about that lol.

bluecajin and vv8s ideas are good, I want to see one in the 228 to see how much power is lost uner the curve

I like the idea. Should yield some good information no matter how you do it.
I would like to see you go into at least the mid-220s duration.
I also think the idea of comparing lsa, holding all other variables static, could be very useful.

I have the cam you described in your post in a 92 with a 5.3/T56.
I really like it.

I would love to see those numbers. It will help me decide if I want to go with a more agressive cam.
