Well we know you want to drop in a 302 and have it almost plug and play , it depends very much on what you have on hand , and the right parts that work , easy back 25 years ago , today kind of a pain but doable, last 302 swap I done was over 25 to thirty years ago , Dick and Reeves are very correct, one the engine is offset some , and the mustang II mounts are how you put them on , if you do use them you will have to move the right side engine support from the side rails and move it back some and redrill/ weld , or just use two drivers side mounts , one of the (do to my age I forgot which one) mounts you have to drill a hole to clear the pin that sticks out from the engine mount , if you are going to use the C-4 try to find the mustang II bellhousing , small housing and tourqe converter , clears firewall , early 66 to 68 passenger side exhaust manifold, cut off choke stove , install pipe on manifold and bolt on when engine is bolted in , (very close here ) drivers side 289 or 302 early fairlane , 45 degree angle , clears everything, oil pan ,mustang ii, yep they are gold but a must , last you can go with the newer front timeing cover with the short water pump , but you will have to make provisions for the dip stick , as for me I made up my own short water pump,setup, used 66 289 timing cover , took a 66 289 water pump and disassemble it , measured the water pump seal to the end of the housing , took off the distance of the bearing length, cut off the extra length of the water pump housing , pressed the flange for the pulley untel it almost touches the bearing , cut off extra shaft on that end , press bearing into water pump housing untel 1/8 inch from seal , press on impeller , used the thin three bolt damper , made a aluminum top and bottom pulley , use 2.8 V6 radiator and have larger necks installed , turn the support on it backwards , the reason is you can trim the top of the frame on the carnand use spacers to move it very close to the front (worth a half inch ) , at least that is how I done it , hope this help some , and lastvuse the V 8 mustang II front springs , they fit .
