Re: MORE FRIGGEN HORSE POWER! SPAM WARNING!
Well as of right now the engine is out, apart, and at the machine shop.
It is being bored .030 over and the heads are getting resurfaced etc...
so that should increase compression. It is getting ported as well and
since we are replacing crankshafts camshafts and pistons I am going
with the 4.2l budget stroker which should yeild about 260 HP

Re: MORE FRIGGEN HORSE POWER!
Cool, it should rock.
I have a 4.0 with 310K km on it in our Cherokee and a spare 4.2L sitting
in my garage.... The stroker idea is enticing.

Re: MORE FRIGGEN HORSE POWER! SPAM WARNING!
Hi Scooter,
Welcome to RAMJW. Not that these discussions can't happen here, but
you really should go check out the yahoo Strokers group, as that is
where most of the technical discussions on these build-ups occurs. There
is even one member is CNC machining silvolite pistons to reduce the CR
of the stroker to a reasonable level. Are you going to deck the block?
It is recommended to restore some level of quench compliance, although
the benefit of this is still being debated. 4.21 sounds odd? are you
going the stroker route, or simply an overbore?
