Got to rebuild my engine not sure which kit to buy. I was also figuring since I got to pull the engine out I might as well get a stroker kit. Not 100% sure where to start. Going tomorrow to get a engine stand and start the pull out. Any help on which kits I need and what I should be on the look out for. Thanks.

I got most of my parts for my 4.9 from 505 Performance. I used a 4.2 block but they also have 4.0 parts too.

IMO the stoker "kits" are over priced for what you get, Hesco is a good site for parts.

also I would go to Jeepstrokers.com and do a lot of reading!

258 crankshaft: 4.2L light weight short nose crank 20$
Connecting rods: 4.2L Rods 20$

(I am doing all the assembly)

Should net 275HP, 315TQ. #'s are based on someone else's build with the same setup but they used the stock cam.

Should also be able to run 89 pump gas.

= rough total of $1600. should be happy with the end result, and not to bad for a complete over haul replacing everything but the block. I also have a AEM wide band to monitor a/f ratio with live data

^Good choice in parts. I had a lot of parts already and only had to really pay for machining and a cam. Also when chosing a camshaft remember to choose one with a larger duration.

You might wanna try just going straight to your machine shop and having them help you find a kit.

This or do the rebuild first then if u handle that worry about the stroker kit later......IMHO

mentalbreakdown00

like stated a 4.2 "stroker" is readily available by using the 4.2 crank and pistons

Mosescase

So u can make a 4.2 just by changing out the crank and pistons ?

Gorillaxj

To do a stroker without boring the block any more then stock will give you a 4.5L not a 4.2l. the 4.2L uses the 232 crank not the 4.2 (258)

you use the 4.2L crank and RODS and use the 4.0L pistons called the poor mans stroker, can be from 4.5L-5.0L depending on setup chosen. The 4.2L stroker is the "mini" stroker using a 232 crank... good info to read here

thanks for the correction for me gorilla, I couldnt remember for the life of me the difference between the 2

Gorillaxj

No problem, took me a few times reading all that info to really wrap my head around it
