Hemi

Postby bob smith » Tue Oct 18, 2016 8:58 am

Just sitting around dreaming.......
A Hemi powered Torpedo, hmmmm I wonder what it would take to marinize a modern 5.7 Hemi?
Anyone know about the compatability of a velvet drive with a TKO or Tremec bolt pattern?
Exhaust manifolds would probably have to be fabricated.
Just trying to stir thing up a bit :)

It would be way cool to see another Torpedo with any appropriate power.

Does the new Hemi still maintain the old style Chrysler bolt pattern?
Back in the 60's the Chrysler was THE way to go for torque. There was thousands of them mounted with velvetDrive.

I believe the Gen 3 Hemis use the same bolt pattern as the LA small blocks minus the center top bolt. The flex plate/flywheel is different but the aftermarket hot rod guys have already gotten that covered. That would be a very cool package! 8)

Wow,
I'm checking it out. It can't be that simple. Whose tranny did Chrysler use?

VelvetDrive was the most common; it don't really matter, Paragon and others all used the "BorgWarner " bolt pattern.
As long as you get the BorgWarner pattern (Velvetdrive) you can bolt up a Paragon, ZF, Hurth, TwinDisc, etc., etc.

it looks like the wet exhaust manifold will be the killer.
Here is a link to all the chrysler exhaust gaskets (bolt patterns), and they look different from the old heads to the new hemi heads

Fab some water-jacketed stainless manifolds like Jenko did for his V12 Jag engine?

I'm still "researching" the feasibility of using a gen3 Chrysler hemi as a boat engine.
Some of the pros are:
Way cool aspect
Torque/hp/weight
Availability
The cons include:
Lack of marine exhaust manifolds
Complexities of the engine management system
I haven't uncovered a "show-stopper" yet. The good news it gives me something to "chew on" while not thinking about more mundane things.
I wonder what it would sound like???

Hi Bob,
For what it's worth, there's stand-alone engine management systems out for the Hemi that are pretty much plug-and-play. There's also the options of intakes for a carb and plug-in ignition control modules too......

Am I helping at all? :lol:

Some of these exotic engine installs are way cool, but I am too simple minded to experiment too much. Just give me a simple package that fits standard stuff so I don't have to re-invent the wheel. :lol: :lol: I'd rather spend my time on getting in the water with a cool exterior. :lol: :lol:
