hi guys, im new here and im in need of some help. heres the quick version. i bought another motor for my 04 mach 1 at a salvage yard out of an 03 mach 1. heres my problem. my flywheel is a 8 bolt patern and the one i got is a 6 bolt patern. is this possable? how can i tell if what i bought really is what they say it is? and is there a way to still put that motor in my stang?

any help is appricated

need more info on your mach, but no it shouldn't be like that if it is a mach 1 motor

i have a 04 mach 1 with manual trans and this motor i bought came out of a supposed 03 mach 1 with auto trans

ok, after reviewing information here ive come to find out that there are diffrent cranks for auto and maual. so heres my real question. can i make my manual trany with origanally 8 bolt crank bolt up to this 6 bolt crank motor. is it a matter of replacing a flywheel?

USMCrebel

you just need a different flywheel and you should be good. oh BTW sell the auto fly to recoupe some of your costs.

Put a GT flywheel in it and the 3650 should bolt right up to it. Don't know if that motor is going to be happy about your 6800 rpm redline after living it's life about 1k lower, but other than that, should work okay.

USMCrebel

it will, but the harmonics could get mesed up and although it won't be noticeable immediately **** will get torn up down the road.

i have both balancers (auto and manual)... with one should i use? right now i have to auto balancer on it since thats what it came with. but there is a diffrence between the to.

USMCrebel

if your a manual car then use the manual balancer if auto use the auto.

that makes the most scence. ill swap them out. i currently got the guy at the salvage yard trying to locate a manual motor instead. lets c if he comes through. if not im stuck with $2500 experirment. these motors are so complex to me, i was probly better of getting my orignal one fixed.
