Can I swap just the crankshaft out of a 4.2 into a 96 4.0 with out any other mods done to the engine?

you need the 4.2 rods...

U also need a case of beer, or two

I cant do it with the 4.0 rods?

Iv got 4 cases sitting in the fridge right now lol. Party at my place tonight

Nope u can't. That's what I have read so far. 4.2 is different length.

Am I invited!?! Lol

the 4.2 crank has a longer stroke than the 4.0. i mean you could put the 4.0 rods on a 4.2 crank but the piston would never reach top dead center.......

I believe the only way you would be able to use the 4.0 rods and 4.2 crank is if you get the Keith Black Icon 944 pistons. Those are around $500 alone.

Hell yes come on down brother

Ya trying to do it cheap lol

How are resourcing the 4.2L crank? If its a donor engine just take the connecting rods out.

Google "poor man's stroker".

Ya its a donor block I wanna end up with the 4.7 low buck low compression stroker but not sure how much itll take to get to that

Start "Googling" dude. I'm not doing all the work for you.
