i am installing a 90 5.0 from mustang to late 70's t-18 4 sp...the old trans needs a 164 tooth flywheel,,,the 5-sp mustangs ues a 157 tooeh wheel..does any one know if the 5.0 ford trucks or broncos use the larger 164 tooth flywheel????? or a stsrter that will match the 157 tooth to the old bellhousing????
Don't know the answer to your first question but as to using the smaller tooth count, you must use what your bell housing calls for and the starter to match that. You can't put a 157 in a bellhousing meant for 164 or 180..... [img]images/graemlins/cussing.gif[/img]
I believe Ford changed the balance factors on the 302, (5.0 L), in the mid 80's. Remember, these are externally balanced engines and Ford puts balance both in the harmonic balancer and the flywheel or flexplate. Since you are crossing that mid 80's line with this swap, you might get some vibrations you were not counting on if you mix and match. B.O.B.
