Blackie's Stroker plans



"Real Jeeps are built, not bought" is what I've heard over and over, so I took it to heart, and this is how things are shaping up:
From what I posted to the Stroker list:
Vehicle {'84 J10 pickup}
Built at: My little old backyard {sideyard?} shop
Block {casting numbers found: 9iiMX09; 4.0L-7; 53005535 with AT cast above, date tag was 10/11/89 and stamped in block was NNN312 below the filter casting. PS: This casting was SOOO dirty, it looked like someone had it under a grinder stand for a year! }
Crank {casting #323547 from my '83 Eagle 4.2L light crank. Ground 10R and 20M At Perpetual Balance (425-742-6066 Lynnwood, WA, an ex-Boeing sub-contractor) it cost $267.16 to balance the whole assembly, including the new balancer, down to .5 gram or less.       They shaved 12 grams off the pistons, 2.7 off the recip end (top I assume) and 3.0 off the bottoms. The crank was originally 16.8 off on the front, and 19.8 off on the back. (He said this was the low end of normal for off balance on a Jeep 6 cyl! Many are much higher.) my new balancer is a Pioneer DA242 plus I'm running the crank girdle and my rods are #352. }
Rods {#352 from the same '83 Eagle 4.2L, resized by Wakefield Sperling in Abbotsford, BC, Canada 604-853-5905}
Pistons {Silvolite #2228 +0.030 and they were balanced too. Bought in Canada}
Head {Renix casting #2686 with 3 angle grind by Wakefield}
Valves {stock}
Valve springs {Isky IIRC or possibly stock. I forget which head they came off as I had 2 in. Ground by Wakefield Sperling machine shop in Abbotsford, BC. Personally recomended enough I drive 150 miles for the work!}
Timing gears/chain {4.0L stock roller set}
Combustion chamber CC {Not CC'd yet}
Quench compliant? (Y/N) {Not necessary with LPG under 11:1}
Quench height {unmeasured yet, but will find out. Head gasket is going to be Victor}
Compression ratio {you tell me! LOL! Need more numbers to find out I guess. 287 cu in with 4.0L block and pistons .030 over and 4.2L crank and rods}
Cam {HO or Renix. Will have both on hand but HO is preferable I think for power and bottom end, but I may retime it with a different chain/gear set}
Cam specs {stock HO 1500 to 4500 RPM curve}
Overbore {0.030}
Intake manifold {Renix is easiest, since it's a Renix head, but I have an HO one as well, but again, it's a Renix MPFI I'm running till LPG is ready}
Throttlebody {HO or Renix, but I'm undecided. LPG injectors are different, but I may have to go with throttlebody mixer}
Exhaust manifold {'89 XJ 4.0L which is stock I think. It has a patched crack on #5}
Flywheel {Renix, rebalanced along with flywheel, crank, rods, pistons and new 4.0L balancer}
Distributor {Renix}
Fuel Injectors {LPG ones from OZ hopefully, or throttlebody mixer if the EPA Nazis don't give in}
Fuel pressure regulator (modified / adjustable?) Fuel pump {not needed with LPG}
Oil pump {stock high volume}
Radiator / style (open or closed) {Closed 3 row for a CJ to fit my SJ from 1-800-Radiator for $131! Anyone want 1? That's delivered most states too!}
Thermostat {possibly Super stat or stock or similar high quality}
Water pump {Flow Kooler later, but stock first till broke in}
city temp hwy temp offroad temp {NA yet}
ECU {Renix},
EGR {yes, stock. It's needed for state emissions even if non-functioning}
TPS CPS MAP sensor MAT sensor CTS O2 sensor Knock Sensor { All stock so far}
Plugs {sticking with Autolite and either '83 4.2L or '89 4.0L HO to begin with}
Cap, rotor, wires, coil {stock but better wires like Jacobs later due to rain short outs here}
Standard / Auto {'95 AW4 auto with NP208 and front hubs}
Modified sensors (details) {none yet}
city mileage hwy mileage {unknown, but expecting 30 mpg compared to regular gas! }
octane run {LPG is 110?}
ping (when) {none expected}
hesitation (when) stumble (when) rough idle (when) {hopefully none}
Est. torque / HP {250HP guesstimate from what I've read. More than a 360 or 401 stock anyway! }
Measured torque / HP {NOT YET}
Age {Not quite finished! 08/07/2000}
Displacement {4.6L}
Exhaust {High flow Cat and muffler, but '89 XJ till broken in or payday next!}
Other parts: Energy suspension motor and trans mounts (part numbers weren't listed, so I compared)
Gears {3.31 open Model 20 rear and Dana 44 with Power Trax going in the front with hubs}
Tires {Avon P255/85/16 on 6 bolt '90 Chev pickup aluminum rims. Equivalent to 33.5/10.5/16}
Lift {3" front springs with SOA and 8" springs in rear, as soon as I sell the brand new 3" rears I have now. 2" body lift to go in along with bodywork and paint}
More to come yet! I'm fighting with the EPA bureaucruds about the injectors as they are scared it may put the gas mileage estimates for CAFE at risk! Fuel economy was done with standard 20% lost economy due to throttle body LPG inefficiencies and gas at $1.60 and LPG at present $0.79, but due to go up! :^(
