I found a company that can reprogram the PCM in my 02 Eldorado, so now engine mods, swaps, tunes, cams, etc. are viable options. It's going to cost $2400-$2700 at a local shop specializing in the Northstar blown head gasket problem to have my engine repaired and oil leaks fixed depending upon how much I have them do to the car. They recommend upgrading to the head stud kit if I plan to add nitrous or a turbo: otherwise use the oversized bolts and inserts they keep in stock. The 4.4 superchargers are affordable in used condition. If they will bolt up in place of the stock 4.6 intake, then it's a no-brainer; we go supercharged. However, will the vacuum valve be enough to control the excessive boost pressures or do I have to use a computer and harness from the 4.4 to regulate it? If the 4.4 cams and/or heads will bolt up, then that is a possibility. However, I can buy a used low miles 4.4 supercharged motor for just over half of what it would cost to get my 4.6 repaired. I just don't know much about how the 4.4 SC motor is set up. Is it a coil-on-plug like mine? Will I have water pump relocation issues? How hard would it be to convert it to a transverse mount configuration? Are the nickle and dime parts and conversions going to cost over $1,000? Either way, the end result must be that my instrument cluster and climate control system functionality remains the same. I understand that the 4.4 is a much stronger block than the 4.6, but I also understand that the 4.6 can handle 1,000 h.p. I'd be happy with anything above 420 h.p. or close. Both options mentioned above would be cheaper than an LS4 swap and the N* would hold together longer than the LS. Decisions...... Who can give some good tech here; I'm stuck at the crossroads.
