I find it of intrest to hear people complain about some one putting a GM motor in a ford vehical. I do not hear the same complaints when some one intalls a 9 inch or a 8.8 in any other vehicals for the performance of said part. I never hear any one complain when some one installs a PG or a th350 or 400 trans behind a ford of mopar because of the advantage. I think all of the big three factory race cars come with a mix and match of parts. I have done the 9inch in a GM and a SBC in my fox. All for the safety and performance advantage of the mix. What do you think
