Well,you used the wrong mounts which is affecting clearance on the exhaust, motor mounts are late Mustang Autozone Duralast 2725 and 2726 transmission mount is a 2253 see these pics for the mods you should do:THE H.A.M.B. If you want to add headers use HEDMAN 88400 they clear everything with zero mods needed.
hey jeff, Ive got to go to work right now but will respond this afternoon but for now, yes front sump [68 stang ebay] I fabbed my motor mounts plates and used a 70 bronco motor mount. but have heard that late 60s mustang motor mounts are a direct fit, not sure about that but wished I'd heard that earlier,making my adapter plates was a royal pain. I dropped ther tranny mount about 1/12 inch and reformed my trans tunnel then mounted a b&m shifter #80776 with a b&m aod adapter kit#40496. now I'm dealing with custom shroud.I put in a double pass aluminum radiator race application [speedway#917-341-22].the trans mount is a 1992 ford van . don't have that #. This is definitely more fun than work but gotta go. hope this helps a little. Oh by the way the driver side exhaust manifold did not clear so I used a 1965 ford fairlane manifold, it does not drop into the steering box but goes straight back. of course custom dual exhaust to be added. I kept stock brakes but went through them completely
It seems that you are the go to guy for info on swaping from a Ford Y block to 351 windsor. I'm working on a 59 Ford wagon. The 292 it had in it was scrambled when I bought it. I'm going with a built 351 windsor and an AOD trans. What motor mounts and trans mounts could I use with little or no fabrication. I'm limited in skills. I was told that I would need a front sump, do you have part numbers. I'm thinking going with a floor shifter and replacing the steering cloumn with a tilt. Do you know what shifter would do the job? Also what headers will fit without clearance problems? I know I'm asking alot of questions, this is my first swap and I want to do it right. Thanks in advance for any help. 59fordwagon.
