360 question

my drivetrain in my 66 is from an 87 gran fury, vin M highway patrol setup. 318 with 360 top end (factory) and a 904 trans. along with whats said above, motor mounts especially, http://www.engine-swaps.com/Pages/ProductsYear/63.66aBody.html#head1 theres much more to consider. manifolds may be a nightmare, factory 273 mannies will be restrictive. theres people on here who have used the magnum manifolds and whatnots. for my 66 i used a 74 valiant 360 drivers side manifold and a center dump 360 (smooth casting) manifold on the passengers side with a sweet manufacturing u-joint coupler (from speedway motors) on the steering shaft. required some steering sector mods, removing 3/4 of an inch from the shaft and machining a double-D face, and clearance is barely 1/4 of an inch. However it worked for me, and i retained the original column shift without any issues. An oil filter 90 degree adapter is required too, along with the drop drag link (if your fish doesnt have one) the radiator outlets may be mis-matched as well, the slant radiator can work, not too well, but it will work. I ran mine with a slanty rad. all summer, averaged right around 210 tops on a steaming hot summer day in traffic. An original V8 rad lower outlet will be on the opposite side as the 90 motor. another thing too is on 65 the output from the trans was a ball and trunnion monster much like the original steering sector joint, in 66 it was changed to a splined yoke/u-joint type. this will need to be adressed, pretty sure it wasnt changed from 66 to 89ish. 904 to 727 tailshaft lengths are different, driveline length will differ accordingly. if your setup doesnt already have a nippondenso mini-starter, GET ONE! it will save a ton of headache down the road. the distributor for 1990 was a hall effect type with no vac adv provision, id change it if you plan on running an OE or MSD type ignition setup.
