ok no more 6.0 for me. need a new cam for the 5.3 (big tex, anyone else)
with the rasing gas prices i not going to do the 6.0 swap anymore.. it sucks but i cant afford the gas. but anyways my go fast parts are going into the 5.3. i have a custom ground cam from comp .218/.218 .563/.563 114lsa i am thinking this will be way to big for my 5.3. is this true? i dont really want to give up to much lowend because i do tow 2 quads and 2 snowmobiles. what cam would be good for me. i do however plan on either getting my trailblazer stall restalled or get a 3000 stall, once my trans blows. do you think a 214/214 or 216/216 might be a good cam for a 5.3, 3.73's?

i hate to say it, but i am thinking about taking off the blower and putting it back to a stock tune so i can run 87 again, this crap of spending $50.00 plus a tank for something that comes out of the ground is nuts.

I'd be tempted to go with a 212/214 114 +0 comp XE high lift, or something similar in a 5.3. Bring it down just a bit more, to say a 208/210 115 XE high lift and youd have great idle and better gas mileage.
when i pull they trailers its mostly on the highways (2100-2300Rpms) so i just want something that wont really be a dog in that range.
the truck is still going to be my race truck, so i want somthing that is going to make some great power. those cams seem like they would be more of a torque cam.
