That's how my swap got started too. The guy that said it couldn't be done got all my business for the little things like a 50 cent bolt and a jug of motor oil. I made sure I brought it by that same shop when I was all done just to show that it COULD be done. The guy looked pretty sour when I pointed out the bolt that I bought from him LOL. :stirthepot:
not onyl is the 3.8 stroker(4.2 or 4.3) a bad a$$ 6 but supersixmotorsports.com sells everything from p&p heads to entire level III engine kits. aftermarket cams and stuff, they also run a baja style ranger.

I think its v6power.net has been diggin up info lately on a 4.5 liter v6 that as far as mounting points is dimensionally the same as 3.8 but totally different beast. The heads are massive as is the block and ported to hell and back. the 3.8 with boost maxes at like 800 hp but the 4.5(discontinued, but avail through collectors) can handle upwards of 12-1500 hp. and gobs of torque.

My credo
it is easier to fix and understand than "her"
its the same as a 302 swap, so its basically a bolt in and cake for the most part.


wiring can be a pia, but if you have the donor its also a non issue.


unless you want the 454 in it. that would be really fun.

if the 4.2L is just a stroked 3.8L....could a Carburated intake manifold from a early 3.8 work on it?

No, the 4.2's block is taller so the intake from a 3.8 will not fit. The early 3.8 TBI intake has the same carb flange that also fits the Autolite 2100 and Holley 2300 2 bbls. I was going to do a 4.2 till I found the block deck height difference.
