I need to know the pin bore for the manley rods. Any help would be greatly appreciated! Thanks....Ken

 

Call Jim at JDM he is putting a set in my truck.

I have no idea what pin bore he is using, but he is putting in Federal Mogal pistons.

 

Thanks Don, I will call Manley in the AM but I'm afraid I will be the recipient of bum info from some clerk. I'm pushed for time cause the new engine is here and ready to go in.......Ken

stock pin size is 22mm

 

How much better are these Manley Rods than the stock ones? Would it be wise to invest $400 in a set for my L? What advantages do they have?

2000 Black "Shadow" L
-JL DiabloSport Chip
-DiabloSport Line Mod Valve
-JL Air Induction
-90mm MAF
-160* thermostat

Installed this week: Bassani Cat-back Exhaust

Mods to come:
3.73 gears
JL 3# Pulley
Lowering Kit of some kind
Denso Plugs

 

Manley offers 2 different types of rods for the 5.4L Modular engine: H-beams and Pro-series I-beams. While both are significantly stronger than the stock (powdered metal) pieces, Manley actually recommends the I-beams for any blown/turbo applications. Here is a pic:



These have the 22mm (stock) pin diameter and are good for 800+ HP per Manley (vs. 700 HP limit for the H-beams).

 

For some reason my image won't come up...here is the attachment:

 

When I spoke to Manley they recommended the H beams for 700hp and under. With the addition of different ARP bolts the same rods are good to 1000hp according to the Manley rep I spoke with.

 

Couple of questions for anyone that has installed these rods in their motors.

1) Did the engine need to be rebalanced, I'm guessing yes, and if so how much weight added?

2) Did you reuse the stock pistons or go with aftermarket? If aftermarket were you able to order a set in the correct weight to bypass the rebalancing of the motor?

I only ask because I have a new motor ready to be installed to replace my smoking stock motor and had given some thought to upgrading the internals of the new motor while I had the chance.

Any info appreciated.

Thanks,

John

 

I am personally waiting for the Manley pistons to come out. You will need to rebalance everything.

 

I'm assuming that's flywheel, right? If so we need some ARP bolts casue I think there's some of us approching that 700flywheel hp already! Sal's got to be close, as does Jim and JL.

Do you know if ARP has a bolt kit for our motors yet? I want to rebuild, but I'm not going to do it then pull the motor again just to add new bolts. I would rather wait for the bolts to make it easier on me.

 

I was wondering does anybody use Pinky Rods anymore I used to use them all the time in the old hotrods and they were the best back then?? Or do they even make them anymore??

 

The ARP rod bolts that come with the Manley rods are good for up to 700 flywheel hp and are made of 8740 material. The upgraded ARP rod bolts which increase the strength up to 1000hp are made of 2000 material. I am not sure if they have a complete set for our motors yet.

 

Like I know what 8740 material is compared to 2000 meterial. HEHEHEHEHEHE.

I just want the strongest stuff!

What about oliver rods? has anybody used them? I want the J&E pistons, but I'm not sure about the manley rods. Are they that good of a rod.
