340 Strokers - who makes them?

[Spartan040]

Who out there builds stout 340 stroker motors? I have an opportunity to get a numbers-matching AAR 'Cuda, but should I manage to get it, I don't want to drive it with the original engine and decrease its value. So I thought I'll get a more powerful, non-stock engine to use in the car for fun on weekends and preserve the original engine to swap in should I ever decide to sell the thing. Failing that, I still plan on going small-block for a future build. So, who makes stout 340 strokers? Or, would a 360 stroker be a more practical, less expensive choice?

If you are by the West Coast, call Brian at IMMengines.

He built my 416 about two years ago.

Crate engines, try Blueprint engines. I think one of the tech is a member on this forum. Search older posts.

Nope, east coast. Florida. I'd be willing to pay for cross-country shipping though.

I would do a 360 stroker over a 340 , the initial cost is far less , I would look for the last series of the LA , from 87-92 with the best heads & roller cam

Agreed: Start with a roller 360 block, cheaper, easier.

a stroked 360 is best, the later hydraulic blocks are the better ones and you can get some good power out of them + trickflow has a new head that blows everything else away for these and will work with new and old SB intake manifolds

Blueprint does a roller 408 stroker based of the 360 Magnum starting at $6400 for a long block all the way to fully dressed ready to run for $7800.  Dyno tested with a printout of your motor, and a 30 month 50,000 mile warranty.  465hp/495tq.  Pretty hard to beat.  They also have flat tappet versions cheaper, but I'd go with the roller.

Any good engine shop should be able to put together a decent 408 and you can go from mild to wild depending on your budget.  I think FITech has a sixpack version of their throttle body fuel injection kit available.  Buildable 340 blocks are getting harder to find for cheap, so many are going with the 360 based engines.

Magnum 408s are the way to go. Leave the 340 alone!

You can make them look stock just like a 340 too.

You don't HAVE to go with aluminum heads either. Engine Quest iron heads are cheap and with a simple port job they flow great.

^^ Converting to a Magnum block requires some modification if you previously had a 360 LA installed correct?

[kawahonda]

Nope! Pretty much a direct bolt-in.

it's a perfect fit and conversion. the LA and Magnum intake ports/threadbolt placement are different though, typically you can't swap intakes. the new trickflow heads can take both

[kawahonda]

And the EQ Heads as well.....which are much cheaper!

mine was built by Rich Nedbal of Mopar Engines a west before he got out of engine building. if I were shopping today I would talk to  Bob Mazzolini Racing and tell them what you want... I agree with starting with a modern 360 and using a roller cam..

Whatever you choose... from my fresh experience over the past year of building a 410 360 (040, 73 block), IF you use H-Beam rods... then most likely the block will need slight clearance notching at the bottoms of the cylinders.... I=beam rods will probably clear without notching.

Also, If you use the Milodon windage tray with a stroker crank, get ready for some serious time spent to modify it clearance to those H-Beam rods... again, maybe the I-beam rods would clear better.

And, finally, IF you use the Mildon Touring/road race pan.. it may have fitting problems around the HV-72 OIL PUMP (grinding needed and re-shaping of the pan at that area, and... slight trimming (~1" x 1") of the K-Frame at the steering box frame area... and the motor mount frame area (vertically about 1/4") on the passenger side... 'twas a hassle spending about 20
+ hours of my overall time.

I purchased most of my engine parts from Hughes... (stroker kit, etc) ... and had a local hi-quality engine shop assemble the short block (discovering the cylinder notching as required).   I hope to have the new 410 running very soon this summer.

@BluePrint Engines   I am trying to find a guy named John.  He is a nice guy, no pressure type.  He works for Blueprint.  From what little I know they stand behind their work.
