For the people who actually have built up their short block with bored out 3.8 liter darton sleeves, how is the engine?
Does it really feel 8% stronger at any rpm?
Does it rev up slower or about the same?
what have your experiences been so far?

the cooling is improved over stock? I thought if anything it'd be slightly worse because the coolant is restricted to the small holes instead of the entire cylinder?
I thought one of the downsides was there isn't much room for boring out the cylinder walls all that much more in case you needed to.

on my standard block motor, temps would routinely exceed 205-210degrees on the dyno...while the darton sleeved setup never stepped up past 195!!!

my question with a stroker kit has always been, if the vq is already pumping about 82 hp per liter at 3.5 and making 287, then with 4.15 would it make 340 at the crank?

My Darton sleeved block does appear to make more power, but its hard to say, since I changed the heads and made other modifications.
Having the 3.8L, my personal opinion, and nothing more, is that I would rather stay at 3.5L with the Darton's. 3.8L leaves precious little headgasket seating surface, and I'd feel more comforting running more boost, on a 3.5L Darton block, rather than a 3.8L darton block.
Hope that helps.
