Hey guys i have a 1984 F100 SWB and at the moment it has the old ford inline 6 in it I am looking to drop a V8 in the old girl I was thinking of a 460 big block i was wandering if it was possible if so how much would i be looking at to do so?
Besides that you will need lots of time, a radiator, transmission, motor perches from a truck with a v-8 (the inline six perches will not work) and lots of little things will pop up that make you run to the parts store over and over again.
Keep the six. If you want more power check out Clifford Performance 6=8 catalogue... The swap is a big job and pretty expensive! Clifford Performance :: Make 6 = 8
The swap isn't hard or expensive, provided you can get your hands on a complete donor truck. All the little stuff gets expensive.
Mine you, by the time you build up the 300 if it's power you're after, you could have done a V8 swap, especially if you buy parts from Clifford...
I've done it and if you have a man trans all you need is the 460 bellhousing, clutch etc. Bolt right in with a set of mounts that cost me a bit over 100.00 Need help let me know.
There are other parts you will need but most can be found. Driveshaft may be smaller, perches sometimes. I did a 6 to a 390 swap and the only thing I had to do was move the perches. All depends on the two trucks...
i have a '68 that i retired(used to roll on dana 60's with 44"superswamper)... .... it has a replaced/rebuilt 460 /c-6 auto that is just stored under the hood ready to pull out. let me know if your interested
