Hydrolocked hemi what should I do?

So I have a 2005 Grand Cherokee 4x4 5.7 hemi.

Basically the 5.7 hemi is hydrolocked blew a couple holes in the oil pan. Vehicle is paid off I talked to the bank they will give me a 10k loan on it. So if you were in my position and you wanted around a 400 HP sleeper. What engine or build would you do. Please give ideas and links if possible. Thank you all in advance.

Re: Hydrolocked hemi what should I do?

i would just buy a used 5.7 and toss it in, Or just buy it new from jeep.

And be done,performance and reliability come at a cost,stay stock.

So no performance mods at all? But that will be boring.

Yes that would be boring don't listen to him. I personally have been thinking of doing a 392 stroker myself. You can buy the short block for about 4k. All you would need to do is swap short blocks. By definition the 545rfe is rated to 500 foot lbs of torque. Go for it.

If you google, there are all sorts of hemi's available in stock displacement up to 7 litres, including from the engine shop that did the Petty folks engines. If you ask any of them they should be able to tell you if you'd need to modify anything else to use their engine. If they mumble, try the next vendor.

392 Stroker 5.7L - shopHEMI.com
The name of the 545RFE only gives a load rating, not a torque handling "number" the higher the number the more torque handling capability. The NAG1 transmission name, the WA580, DOES give an input torque handling capability in the number, 580 newton-meters or 428 ft lbs.

Re: Hydrolocked hemi what should I do?

Sure does, probably why they have gone to a different transmission, 8HP70 capable of handling 700 newton-meters.

Whats the difference between load rating and torque handling?

Re: Hydrolocked hemi what should I do?

It was poorly worded, my fault.

The difference I was trying to get at is, unlike the NAG that uses the last 3 numbers in its name and the new 8 speed trans which uses the last 2 numbers in its actual torque handling ability in newton meters.

The RFE just uses 1-8 (may go up from there but 8 is the highest chrysler trans I recall). In my training I have never been told that the number has anything to do with an actual torque just 1 is weak and it gets stronger and stronger as you go up the list to the heavy duty 68RFE.
