151 to 4.6 stroker build

[eastin82]

hello all jeepers. been lurking, reading, and planning for a while on hear and other sites trying to get this stroker build up and rolling. ive decided to post my progress hear since you guys are far more nowledgeable than i am. i have a 91 xj 4.0 thats going to become a 4.6 and replace a gm 151 in my 81 cj5. when i started researching engine swaps and realized that i have some of the main parts laying around the barn it was a no brainer( couple of 258 in the corner of the barn). ill post pics of some of the things ive come up with so far. i had pics of the engine as i took it apart but i moved a box to the ground that contained engine harness and camera and my stepfathers dogs got ahold of the camera. so ill get some pics of the block and head tomorrow.this is what i plan so far not everythings rock solid(just what ive purchased so far).
91 4.0 complete engine (purchased)
92 wiring harness from a manual(purchased)
4 weight crank that needs to be turned(already had)
4.2 rods casting number 707 should be back soon(already had)
sealed power 677cp30 dished to 23cc(falcon)
comp cams 68-231-4(need)
clevite bearings (falcon)
diy port and polished head 3 angle valve job checked for flat(need)
valveterain?
timing set?
bore throttle body
header?
air filter?
and other things needed to fit it in cj(inline fuel pump,radiater,cps relocation kit,clutch,rebuild t176 and dana 300, vss, engine mounts, ect.)
.0025 deck height take off .043
gasket kit? .044 mls head gasket compressed(need)
quench of .0465 scr 9.44 and dcr 8.04
any suggestions on how high i can go with dcr and run on premium. should i deck more?

my project!

[eastin82]

rented spring compresser today got all springs out and gaskets scraped off several parts. trying to prep everything for paint.

[eastin82]

crank should be done first of the week. then i can order main and rod bearings. i order them for 91 4.0 right and that will work. more pics!

Yes order main bearings for the year of the block, the split is '90/'91 so compare them to the old ones before you install them, there is the possibility of some cross over there! they moved the locating tab after 36 years of being in the same location!?

[eastin82]

few changes to the recipe ive decided to get zero deck clearance. i should end up with scr 9.49 dcr 8.3 .044 quench ivca 52

[eastin82]

what ive decided on

[Muad'Dib]

The calculators print view would have been handy there

[eastin82]

picked up the crank today looked great. they just had to take 10/10 put up some pics tomorrow and order bearings

pics of the crank

[eastin82]

hear are a few parts, im waiting on main and rod bearings so that i can take block, head, rods, pistons, piston pins, crank, bearings, main caps and bolts, freeze plugs, and cam bearings. having it bored 30, decked to 0, hot tanked, magnafluxed, freeze plugs, and cam bearings installed, and balanced. anyone think im forgeting anything or should have anything else done. after head is magnafluxed and hot tanked i can clean up the ports and then take it back to get my three angle valve job.

well it looks like ill be notching my clevite rod bearings. why would they sell something that isnt right? machine shop said they had to finish up one build a 400 then they could start on mine. thats kinda a good thing since im gona have to drop about 500 into my 4wheeler before then.

I wondered the same thing about the bearings myself. How hard is it to cut a notch in the bearing? It would suck bad if you didn't know about the notches and put them in, and had a failure. I'm sure they wouldn't admit to it being there fault as well.

[SilverXJ]

Its pretty easy to notch them. Take a look at my build tread to see some pics. I just used a Dremel then debured it with a file.

[eastin82]

yea i thought i saw that in your thread and read over it last night looks good!
