i'm building a stroker 4.2 crank and rods, in 4.0 going into 87 yj frame off, which obviously came w/ 4.2 not 4.0.
anywho, i'm thinking of the nv3550 trans, any input on this, i think the nv 4500 will be too expensive, i've heard that it is too large, and requires a lot of mod. t-18 trans is cool, but i want 5 speed, i want to wheel hard, but drive to work also.
any input on trans, and any info on the stroker would be nice to.

Not much to say either you get the nv3550 or the nv4500 its a personnel preference I guess. You already know as much about them as I do. For the engine I am the wrong guy to answer this question, you see what I did to my jeep. lol wish I could help more. Have a good one

thanks for the reply, do you think the nv3550 is significantly better than ax 15?

what do you want to know about the stroker

Thats Mine

looks good. is it in and runnin? how do you like it, what compression is it running, witch injectors did you go with, i have some northstar injectors i robbed from an engine job i did, which i don't want to do again. i know mustang injectors are supposed to work. mine is going into a yj with 4.2 originally, i think i can just get the crank nose machined down and run all accessories from later 4.0. there's a lot to go into this, so tell me what ya think, and expereinced from doin it. i want to use 4.2 crank and rods, where did you get a wrist pin to connect 4.2 rod, to 4.0 piston, what cam did you run? i could probably go on, but finally someone that has some input on the stroker first hand is great. thanks

its not in and runnin but we are finally there its me and my dads project he's mostly the the knowledgable one i just give him the money and he spends it i am pretty sure we ae using 24lb mustang injectors we used 4.2 crank and rods the 4.0 we are using cam from a 90 cherokee a ho head from i forget what a clevlite cam i'll get more info and get back to you but mine is goin into a 94 yj with a2.5 so we just the under hood wiring we have to move the motor mounts etc which means me have to find a place to get them welded in being that we dont have one..........i see you are in beach park i'm in berwyn
