429 engine qwestions

im rebuilding a 429 from a 71 or so, mercury car.just as a side npote im 17 and doing it in my garage with my dad i have pics of the engine if ne one wants to see aask. i have plans to put it into my 1980 F250. does anyone have tips or something i should know about swapping the engine. also if anyone has cost saving tips while im rebuilding it. im not doing a total overhaul we have it down to a short block basically cause its in good condition. also iknow im begging but most of you may know it isnt cheap to rebuild an engine if anyone has something they could possibly contribute to my cause used good parts whatever you can give it would be greatly appreciated.

youll need a c-6 from a 351/400m or 429/460 to start off with.also need a double drop oil pan with the pickup tube,460 truck exuast manifolds,and engine mounts.the mounts can be had from autozone for 50 bucks/pair.when you get done with this itll get around 10 mpg but since your 17 ya probaby got a heavy foot(i did at that age lol)5-8mpg is more like it

when asking for parts it would be wise to post your location. If you click "user CP" ....edit profile...add your location. It will show up above your post count.

they didn't put 460 in untill 84 if it is a 4x4 the oil filter needs to be relocated or block up the motor 3/4 in andyou need a 45 degree oil filter mount from a van with a 460 this will work or modify the cross frame
