Topic: 2.5L stroker crankshaft

[xjcrazed]

I believe that is what was discussed in the Hey Jeffy Got a good one for ya 3.0L GM motor. and 2.5L Rebuild using a commercial 3.0L stroker? threads.  I believe the conclusion was that this might be a possibility for the Pontiac 2.5L "Iron Duke" engine, but not for the AMC 2.5L.  If you have any further information to the contrary I'd be happy to hear it, but it sounds identical to what was discussed previously in the linked threads.

yeah, sounds like it was the GM marine related so for the Pontiac motor.

i've hear the exact same thing a long time ago but after countless hours of searching i came up empty. Don't quote me on this but i somehow remember that was an option for the pontiac 2.5 that was in the Jeeps initially (iron duke or whatever its called) and that had a marine 3.0 equivalent that you could use the crank and rods from, again it's been a long time since i looked into this so i could be wrong.

Google Ed Pink and Pontiac midget    They Pontiac dominates many of the classes...

On straight methanol and full build 495 to 595 HP is possible.. Just $$$$$$$$$$$

Not even the same engine as the AMC 150 though.  The Pontiac Iron Duke 151's have a long history of squeezing blood from a stone.  Lots of fast parts for them.  Hot Hot Magazine was able to get 600HP out of one, IIRC.

The marine engine that I was told about is not a GM engine.  I've seen some of the Iron Dike hop ups and this is not the same engine.  The Chrysler tech knows that I've got a YJ and I said the same thing about the Iron Duke engine. he has an ID powered Jeep so he knows the difference.  He said that this IS a Chrysler 3.0L inboard engine compatible with the 2.5L.  I had another friend that works for a marine dealer with access to computer records look up the engine and it does exist in to versions a 2.8L and the 3.0L.  They are considered dogs in boats.  He tried to download the manuals and tech specs for it but they want about 300.00 for the files.  He is still keeping an eye out for a dead one for me.  I haven't found one yet but still half looking.

does he have a designation for the engine? (engine code or something)
what was the name of the manual he was trying to download, maybe we can find it somewhere else.

Look up a 1986 Mercruiser (Gas) 140/3.0L, 4 cyl

By diagram looks a lot like a Jeep Motor.

  But would need to do a bunch more research.

based on this

http://www.boats.net/parts/search/Merc/Mercruiser/1986/01402006/CYLINDER%20BLOCK,%20PISTON%20AND%20BEARINGS%20(140-3.0L-181%20CID)/parts.html

bloc is totally different, also the piston is flat top and found in another place that the bore is 4'', so they're different

Too bad this is a pushrod engine and not like an SOHC 2.5/2.3/2.0 Lima from a Ranger/Pinto/Mustang. Those guys get Volvo DOHC head swaps! They also get cheap bolt up turbo goods from Turbocoupes and Mekur's and SVO Stangs.

Right now there is someone working on a 1000hp Lima on Turbo Ranger forum, haven't checked in in awhile tho.

Here is a 2.8 liter short block Lima, ready to bolt in.... http://www.raceeng.com/p-10301-2850-short-blockbillet-crankgp-each.aspx

I do hope you find a solution, but I'm not going to do much but show you how much easier it is for people with a different badge on the front of their cars...
