Cam / Heads Queston
#1
Hey everyone, Looooong time lurker first time poster. Love the site and the information provided.
I've got a friend who works full time for a known engine builder whos currently selling off his motor and I was just curious as to what everyone thinks.
His truck is an 04 short bed with a 5.3. He's dumping the motor completely to go with a 6.2 and other work.
Here is his list. He put 20,000 miles on this setup with no problems. It was his DD.
-Heads ported w/ bigger (1.950") int valves
-cam: 218/224 113.5 lsa .530"/.539" lift
-port matched intake manifold and ported drive by wire throttle body
-ran 13.9 1/4 mile in my truck, stock trans
-Comp 918 valve springs
I have an 04 CC with air intake and magnaflow cat back, and been dyno tuned (which I realize will need to be completely redone). It currently has 66k miles with stock trans (but factory trailer package, which I would probably add a tranny cooler).
I would add long tubes and ORY also to get the most out of whats done.
My questions (even though I trust him, just want a second opinion).
My truck isn't really a DD as I have a work truck, but off hours I drive mine.
Is this a pretty decent setup? I'm just looking for a decent power adder, not a drag racer.
Is this a setup thats streetable? I think in my case I would prefer the cam would have more low - mid range tq/hp than at higher rpm's
That seems like a mild cam just looking at the specs, does that seem like a fair judgement? I'm after the power adder part, just not to hot on getting a real loopey cam. I'm no racer, just would like some more power, do the occasional pulling of my boat or small trailer for motorcycles/quads.
Would / should there be any other upgrades to the internals of the motor? He just had stock bottom end.
Thanks
I'm sure I'll come up with a few more questions.
