I've done some research but not coming up with a ton. I've seen a small handful of threads but not much info.
Anyways, we've recently picked up a 2000 4.8L out of a truck. Deal was too good to pass up so we figured we'd just buy it and leave it in the garage for a rainy day.
Anyways, just curious on boosted results. How much power you're getting out of them on stock internals, etc. I may just end up throwing it in a Fox Mustang for a quick beater car when me and my buddy's cars are apart or whatnot.
Thanks,
Adam

im running a boosted 4.8 and that is all I will run. compared to many 5.3s that rev to 6500, im giving up 10% cubic inches but gaining 18%rpm by shifting at 7700 because of that short stroke. I'll take that trade any day
