Hey guys, i've seen two stroker kits out there for the 318: One turns it into a 350 with
-custom machined cast pistions
-STAGE 1 RODS w/ARP WAVE LOC BOLTS
-3.578 STROKER CRANK
-SEALED POWER CAST RINGS
-CLEVITE MAIN & ROD BEARINGS
and there are a bunch of other options you can add to the kit... What would you guys add if anything. Does this kit seem like a good idea? Only 795 bucks for the basic kit. I'm thinking i might do this, but i want your opinions on it.
There's also a 390 stroker kit too, but thats out of my price range.. costs about 2200 bucks.

I contacted these guys a few months ago. They stressed to me that these stroker kits were for race only! That Sucks!

Putting in a stroker kit will require machining of the stock block. In general, a used 360 block is relatively cheap - much cheaper than a stroker kit. It's basically a free 42 cubic inches if you're going the rebuild route. That's why you do not hear of people stroking 318s very much. Just swap in a 360 short block instead. Cheaper HP than the stroker route.
So you guys saying swap a stock 360 over stroking the 318 or do mods to that too. What are some price differences? Thanks

I'd say go with a crate 360 that is already modified. Summit has a crate 360 that they claim pumps out 380hp. It's like 4 grand :crazy . That's not bad when you compare prices.
www.summitracing.com Type in "crate motor" in the key word search.

My Grand is fast I ran 10.87 in the quatrer mile on 23" tires at PIR. It is really souped up. Has any blown a grand Cherokee? that is what I want to do.

They're basically putting a 360 crank into a 318 and upgrading the rods/pistons. Rod lengths are stock. I have a 360 crank for sale, which should just bolt right up to the rest of your bottom-end and bring you up to 350cid. Email me at email@example.com if you're interested.

Ihave ran both engines in plymouth baracudas.
The 318 is a much better pachage. Sort of like the difference between a 125cc motorcycle to a 175cc the 175cc will be a pig that wishes it where a 250cc and the 125cc will just keep on putting a grin on your face.
The hardest part of the 318 build if carborated is getting real 4 barrel heads they are very rare stock. I have only owned or seen one 318 that was a true factory 4 barrel set up.
Thats My 2Cents :eek:

Remember that the Magnum engines are different from the old "LA" small block chryslers. Also "B" and "RB" engines would require a whole new drivetrain as nothing you have now would bolt up or be strong enough.
