Bore a 4.8L?
Hey guys, I have been thinking for awhile if a guy could bore a 4.8L from 3.779 to 4 inchs. Put in a set of dished pistons.
I figure if it could be done, it would create some sort of high reving monster. The displacement would go from 293 to 328!
I figure for going bigger in cubes it would be a relatively cheap upgrade, since it will just require another set of pistons and a bore job, and all the related gaskets and such!
Maybe slap in a high rpm cam, and a set of pacesetters while i am at it. Get it tuned and extend the rpm range a little higher! And a higher stall converter!
What do you guys think?
Kind of sounds like a LS1 based 327 to me!
p.s. 327 stickers on a 5.3L is

what if a guy took a used iron 6.0L block, bore it to 4.030, throw in a 4.8L crank and rods, build a little high revver.......
has it ever been considered? I guess that a guy would be better off to go with a 6.0L at that point instead of "de-stroking" an engine!
there is no replacement for displacement!
