    Thank you for this reply, knowing which harnesses I need is super helpful when looking at these packages. I was looking at a "master kit" but it seems it would give me lots of redundant parts.

    Get the iron block 5.4. Swap in a forged bottom end from VMP while it's out of the car. Bolt on a big blower and E85 and crush shit.

    However if you're planning on just bolting in a GT500 long block and being happy, prepare to be disappointed. You'll be looking at about 440whp stock, I got mine up to 550whp with an intake, pulley, and tune though. Not sure where you are now but you have to be close to 400 already so don't expect a massive jump just from the install. Bottom end will take up to 800whp before you have to start watching how high you rev it to protect the rods.

    Based on MPH car makes around 425 WHP as it sits.

    Sounds like Iron is the way to go. No plans to build the bottom end right away. Once the bigger blower is in the cards I will definitely consider it, but no E85 available around here, so I might have to stick closer to factory compression ratio on a forged bottom end for pump gas 91 friendliness.

    With the GT500 engine, a TVS, and 91 octane with the correct supporting mods you should be able to get the car up to 600whp pretty easily. Throwing mine on the dyno Friday hopefully, but we have 93 down here.

    Well, I have a 2007 Shelby GT500 donor car en route. Should come tomorrow. Should be building it in the new year.

  7. I'd go aluminum for the weight. Aluminum has proven itself beyond expectations as long as you don't cook it. Iron block shelbys are even more nose heavy pigs than the mustangs already are. Word of advice, if you want the car faster, ditch the manual and go with the 6r80 6 SPD auto. I did and I'll never have another manual. Went from 7.13 to 6.87. I can save you some money on the quick6 also

    Too late to go aluminum...

    I’ll lose a couple tenths and keep my 3rd pedal. I have a things for manuals.

    No it was in Surrey, British Columbia, Canada at a salvage yard. I had it shipped to Calgary, Alberta where I live. I watched lots of Copart and IAAI auctions but, shipping, Exchange Rate and duty would have killed me! The price made sense and this way i hope that I don’t have to source too many parts for the swap. This car runs and drives. It either soft rolled (no airbag deployed and windshield in tact) or something fell on it.

    Got a little bonus at work, and the engine is out so I figured a BMR K member was in order.

    K member is in - it was a pain even with the engine out. Ball joint fought us.

    GT500 engine and transmission are out. Should be back in the GT tomorrow if all goes well.

    Nice progress and find on that car. Also, I really really want a bmr k member. I don't know why, they are just so cool.

    Got more work done last night, AC Condenser, radiator, heat exchanger (factory H.E. is TINY!!! Ordered a VMP triple pass dual fan unit) fuse box, PCM, fuel lines power steering.

    Next up is exhaust,O2 sensors and wiring in the IC pump. Might have it running by the weekend, but I’ll need the locksmith to come over and program my PATS keys to the new PCM.

    Project is going smooth so far.

    I also ordered an MGW GT500 shifter as the factory unit is really flimsy looking and I loved my MGW on the 5 speed GT trans.

    And I ordered a Ford Performance 1 piece aluminum driveshaft, Metco driveshaft loop and Ford Performance hood struts...

    Budget has officially been blown.

    Keys got programmed today. And it fired first go! I seem to have a TCS light on but no other lights on the dash. I also seem to have a belt issue as there was quite the squeal on start up and no it’s not the blower. Lol.
