Eaton Swap Parts List Thread

[tdotcv]

The Metco site list several options for the Ring Size: underdrive crank pulley (6.55"), stock-diameter crank pulley (7.40"), +2 lb crank pulley (8.00"), +4 lb crank pulley (8.60"), +6 lb crank pulley (9.10"), +8 lb crank pulley (9.55") and +10 lb crank pulley (10.00").

Also, there are several options listed for the Supercharger Pulley Ring Size: 2.70" Ring, 2.80" Ring, 2.90" Ring, and 3.00" Ring.

Which size combo is recommended for the stock block (+2 lb crank pulley and 3.00" ring)?

If you're going with a 3.00" ring, you may want to consider staying with a stock lower as a 3.00" (i.e. 2.93" to 3.10") and 2 lb lower is going to make between 14 1/2 and 16 lbs of boost, which is a bit steep for a stock block. (see attached boost calculation table).

Suggest you contact Rick or Kristi at Metco and ask them what kind of combinations they can provide, I'm pretty sure they've got a wide range of upper and lower ring sizes and could put together a package for you. Tell 'em Rex sent you. (NOTE: a stock upper may have an interference issue with th hood liner, but that can be addressed by either removing the liner, or cutting a small relief section in it directly above the upper pulley).

I bought the 2# pulley ring and will go with a 3.1 or 3.4 upper combo. Thanks for the information. Took me a while to figure it out but it's easy to use now that I get it.

Where do you get the screw and bolt to plug lower intake at. Website said I need to order 10 and 4 of of bolt and screw.

Are you talking the intake and blower mounting bolts or something else?

Looks like two different things you're asking about.

If you purchased all the front belt pulley components (bridges, brackets, cages, etc.) from a Cobra you've got a bunch of extra stuff that you don't need for your Marauder.

The lower pulley is the driver, and the upper (supercharger) pulley is the driven. Depending on size combination (e.g. larger lower/smaller upper) you'll generate higher boost. You only need to select one of each (i.e. one lower, one upper).

The 3.1, 3.2, etc designation is upper pulley diameter. Stock is 3.6 inches. The lower "lb" designation is boost increase over stock configuration. The Metco site references lower ring diameter for each incremental increase.

If you're doing a swap on a stock block, you'll prolly want to stay between 10 and 13 lbs boost. I'm running a stock upper and 2 lb lower combination which is putting out around 11 lbs boost. As a reference, with my current tune and mods and 11 lbs boost, that's good for about 430 rwhp.

I highly recommend the Metco pulley kit, with the quick change upper and lower set up, you can change out upper and/or lower rings in the future to modify performance, much easier than using a puller to remove press fit pulleys.

The charts which are confusing you are belt lengths required for the different pulley combinations. A stock upper/lower set up requires a 53 1/2" belt, a stock upper/2 lb lower uses a 54 1/2" belt.

Can you see if this can be added to whats on the first page, when you explained it it helped out soooo much more, I was very confused read it also before you broke it down thank you.

Been a while now, but isn't that just a 1/2" pipe thread? Any plumbing isle will have that for less than a buck.

Tried the swap, smashed heater hose like it said but now car not running right. Looking to replace with New hose. Bought one from rock auto but will not fit right. Getting pretty irritated with car sitting and not running right so can someone post link of THE RIGHT heater coolant return tube for marauder or cobra since I'll be doin the swap and would RATHER NOT smash again do to this headache. Thank you.

[guspech750]

Bob and I just gently messaged the tube. It didnt take much. We put some white paint on the tube to see where it rubbed the lower intake and gently messaged the small area that needed a little message. Tried to keep a nice cylindrical shape so fluid would flow through it nicely and all is good for my swap.

That coolant tube isn't going to make your car not run right, unless it's not allowing the lower intake to seat properly and causing a vacuum leak.

But you sound irritated with people giving you free advice, so good luck throwing money at the problem!

Agreed that the coolant tube shouldn't cause running problems, ^^^^ check for a vacuum leak.
