:shrug: need some help was curious about building a stroker 3.8. what I am told is that I can use a crank from a 4.2 f150 or I could swap out the entire block if this is true what do I need to do if I go with just the crank or if I use the entire block can i use everything else from my engine-- heads, intake, tranny, etc.... I have a 2000 3.8

Strokers

To my knowledge there are 2 companies with stroker kits out there links below. You need more then just the crank I think. I am pretty sure you need the matching connecting Rods. Your best bet is to buy either a stroker kit or stroked short block from one of the links below. If you buy the kit you need to pull your engine out and take it a part pull the pistons out and put the new crank, pistons, and rods in. If you buy the short block all you need to do is pull you engine out and swap you heads, intake, headers, oil pan ect. Its far less work then the kit, but more $$$. I like the idea of buying the short block and if you get into serious racing you could buy another oil pan and keep the old block, pistons, and everything oiled and keep it in the garage or shed just incase you blow the new engine.

me personally I like supersix motorsports better they have dyno sheets and morana v6's site is harder to navigate plus morvana is in canada so I am guessing the shipping will be more.
 
to answer you r question ues you can just swap the crank and have a 4.2 but idk how much hp it would be worth i cant attest to! a bunch of guys at 3.8mustang.com and v6power.net have done it go there and ask some q's!!!
 
you can just get a 4.2l crank for about 150-200 bucks and get what ever rods you want, oem or you can get forged what ever you choose. the 4.2 crank is neutrally balances thus you will need matching flywheel and harmonic balancer if you do not have a mid 01+ v6 mustang. If you are going though this trouble i would buy forged rods and pistons, and decide if you want High compression n/a or lower compression for boost later on.

finish it up with heads/cam/intakes to match you final ideal of where you want your car to be at.

with all said and done you should see 260rwhp and 280rwtq all tuned for good daily driving with an n/a motor (ive seen more just a good estimate of what you will get) and with a boosted car 300-400-500 what ever you get it will depend on the boost and what not. with a blower you will also need injectors, maf, fuel pump and what not... just an n/a motor you may not need anything, if pre 99 probably need at least injectors (maf to match)
