difference in power levels.... I was thinking about the difference in power levels between the two following examples:
5.3L Truck A4
5.7L Fbody A4
Mods
5.3L w/ full bolt ons, 220 cam
5.7L w/ full bolt ons, 220 cam
5.3L = 320rwhp
5.7L = 380rwhp
Please do not knit-pick. This is for discussion purposes only. Okay, so why does the 5.3L make 60 less power to the wheels? Please list what you see as a loss and if it's a bit wacko, give an estimated power loss... at least an assumption.
I'll start off:
*Bore size
*Compression
What else?
