250 swap
Glad to find all this activity regarding 250 swap as I am attempting this right now. I have an uncut 66 that I swapped a 200 for the 170 several years ago and I beleive it was from an early 80s granada and was a true drop in swap. More power than the 170 but seriously hampered by the 3 speed trans. Currently have front springs from ebay that were sold as Duff 2" springs and rear springs (5+ overload) I got from a friend that purchased them from Wild Horses that are suppose to be 2.5" lift however they must be worn out as they are about stock height, I am going to install blocks. Also the front springs appear to lift more than 2" but they were probably intended to lift 2" with a v8. I know Duff made a 2" front coil because I have an old catalog that shows them. I have 1" body lift blocks and new rubber bushings that are to be installed during this swap. I also am doing the NV 3550 Advanced Adapters during this swap. My 250 is out of a 70 Mustang.
The 250 with NV and Dana 20 are in the vehicle right now and there are problems mainly with the height of the engine. I have read about slotting the holes on the mounts and this looks like it will lower about 1/2 to 5/8 inch and with the 1'" body lift it may work with the stock hood but I have my doubts. I did get a low profile air cleaner from the Mustang and am hoping for the best. If any one has experience with this I would appreciate your input. With the the front 2" springs I think I will have enough clearance between the Dana 30 and oil pan as long as do not use the Bronco for jumping. I would feel better about having a modified oil pan but will have too look at that later. Also if any of you are planning this same swap the Advanced Adapters trans cross mount does not line up with trans mounting bracket for the NV as the package was engineered for a v8. Also make sure you get the alt, pulley, power steering brackets as these do not interchange with the 200. I am having to look for these now.
Thanks in advance for any help. I will post updates and soon I hope driving impressions with this drivetrain package. I have owned this Bronco for over 20 years and think this will be what I have been looking for.
