6.1 Rotating Assembly, Fuel Supply, Questions.

This is all to work with my 84/75 Turbo Mega Cab

Rotating Assembly:
Normally I'd go thru SummitRacing.com but I don't see
anything for 6.1 RAs, so what are some good sites that
I can go to for Crank, Rods, n Piston Kit (Forged Parts)?

Fuel Supply:
Currently I have a Stock 5.7 Hemi (it will stay stock), In
time I will swap in a SRT8 6.1 (Lil bigger cam, 10:1 Comp
Maybe .30 Over). What Injectors n Pump will work for both
engine set-ups. I want to buy just 1 set of Injectors n Pump.

Complete rotating assembly for a 6.1 Block , all you'll find is stroker kits
405 HEMI 6.1L Based Stroker Kits by Modern Muscle Performance

https://www.cnc-motorsports.com/call...rankshaft.html

There are afew more places but these are the two that came to mind
Stock stroke Crank, Ebay is your only real choice right now, they pop up in the $350-600 range about once a month.
Alternative stockish stroke is Molnar ( MOLNAR TECHNOLOGIES )
has a 3.59 NHRA crank (345-3593JB6F ) it'll set you back $960+ I just Dynoed a 372 (4065X3.59) 6.1 last weekend with the 359 crank.... , it's an RPM freak.
rods and Pistons can be found in the usual places.

I’ve seen Inertia Motorsports has an option to buy a refurbished 6.1 stock crank, but I’m sure that depends on availability. It’s worth a call there, Stu’s a good guy to talk to about the hemis. Other then that, keep your eyes peeled on classifieds on Facebook swap meet pages, LX Forums. Luck is gonna play a big part in that. Also Stu at Inertia can put together a 360ish cc forged stroker combo with a 6.4 crank for about $2200, I’d highly recommend a conversation with him, I got my stroker cam through him

Above I mentioned possibly .30"
over, I'm not gonna do a stroker.

It's half of the reason I'm doing a
6.1, cause it's like a doing Stroked
5.7 So I'm getting the extra cubic
inches, better heads intake without
all the extra machine work required.

I'm essentially just gonna rebuild it
very close to stock specs, only real
differences are fully forged rotating
assembly, 10:1 instead of 10.3:1, diff
cam, injectors & a 84 hanging off of it.

The stock 6.1 crank is already forged. All you need is forged rods and pistons

I know the stock crank is forged I
was just thinking about replacing
the entire rotating assembly since
I'll likely be putting 18+ PSI onto it.

I don't see the point of taking a good forged crank out and putting in a different forged crank for another $1000. As far as I know the crank can handle a ton of power, and its got the 4 bolt reluctor wheel, only issue I've heard is oiling issues with really high rpm like 7k+. Rick probably will chime in on that crank

I guess I'm just a lil leery taking
a 180k to 225K stock crank and
putting 18+ PSI of boost on top.

At 18 psi I would save that $1000 towards the RFE transmissions you’ll be eating every month haha that’s about the most boost that anyone in a ram is running, let alone in a heavy 2500
