Rebuilding my 5.0

I am getting ready to take my T-Bird down for a rebuild (its a 1993 with a 5.0) and am looking for advice on how to build the motor. So far as I know the only modification that has been done to it is it has a high lift cam installed, and an MSD ignition. I am looking to maximize my horsepower, but I am on a budget (a few grand) and I dont want to overdo it and do something that will damage my frame or rear axle ect. Unfortunately finding information on what the T-Birds can handle is not easy so I am hoping somebody can help me here.

Thanks in advance!

I'd first decide what power you want. 250 horses? 300? 500? 10,000?

The transmission will be the next logical step. Might as well figure on having it rebuilt if you're going to be at the 300 pony mark, or more, or if it's got a shiznit-ton of mileage, or is already giving problems, etc.

Then the rear diff. and the IRS stuff. I have no clue on upgrades to that, but the supercoupe forum would surely have that info.

The rest is common sense stuff, bigger brakes, sub frame connectors, good tires, maybe some lowering springs and a SC front bumper for a little more aero cleanliness.

I will just say here now, that the block (stock block, anyway) will be the limiting factor, assuming you have or are going to beef up the trans and rear. The blocks tend to want to split and come apart around the 500-600 horsepower level.
It's not a matter of if you split a 5.0 block, but when.

Put a TFS1 cam in, P heads, cobra or explorer intake, 1-5/8" headers and dual exhaust at least 2.5' in diameter, and you'll hit close to if not at or even over 300 horse. Will likely need a tune if you start adding N2O, or forced induction.
Those cars are heavier than the Fox 'Birds we're used to here, but all the same, a well put together 5.0 will speed it up a ed good bit.
'98 Explorer 5.0
'20 Malibu (I know, Chevy, but, 35MPG. Let's go brandon, eh)

With such a heavy car....build the engine for torque....it will preform so much better....nice set of 3.73 will also help.  What is your goal???  The MN12 are fat rides...why they work so well with the supercharged 3.8!
