thanks
my 69 F100 in the picture is 12.5 of lift and 38.5's. Currently I had to degrade it to daily driver so I took out 3.5" of lift and swapped on some smaller tires
my other truck that I use to haul the camper and tow the Jeep is a 78 F250 with 6" of lift and 33's, and a 460 on propane

thats the truck I plan on getting eventually, if all the stars align just right and I win a lottery I'll pick up a 7.3 diesel powered truck
in the meantime I keep on wrenching.
Just installing the new motor mounts on the 460 today to replace the broken L&L mounts.

wow, this looks seriously complicated. the 390 is going to be a pain to get into your truck, and im assuming the 289 isn't the same block as the 351. you coulda saved yourself alot of headache to just build a 400, but, im sure you already knew that. no chance of trading the 289 for a running 351 or doing something a little simpler?

I have built many "FE" motors(usually 428 but same thing as 390) and 460 motors. Although I am a huge fan of the FE it will cost you more to build than the 460. Also if you are going to build an fe build a 428. You might have to do some searching for a block but they have a lot more torque stock than a 390. You can get a lot of power out of an fe but if cost is an issue parts are cheaper and more available for the 460. MY ADVICE TO ALL IS IF YOU ARE SPENDING A LOT ON AN FE MOTOR MAKE SURE THE ENGINE BUILDER IS FAMILIAR WITH THIS STYLE OF MOTOR. THERE ARE A FEW TRICKS WITH THE OILING SYSTEM IN THESE BLOCKS TO DO TO MAKE THEM BETTER(OPENING UP OIL PASSAGES,ETC.). I love this motor and it is an awesome motor when built properly. I'll shut up for now.

Your 351m can be rebuilt to a 400 with the 400 crank, the bore is the same. There are also aftermarket stroker kits that will get you to 434 cubic inches.
Although I consider myself an FE guy, the 390 will require a different transmission and mounts in your rig. The 460 will bolt up to the transmission in your truck now and would just require mounts and accessory changes. There is no substitute for cubic inches. Good luck with your swap and build.

big block small block stuff is more of a chevy thing really. the 460 and 390 arent by any means interchangeable. i went to throw a 460 in my truck, bought the motor, then looked into what was involved and decided i could have a hot 390 for the price just to get the 460 in there. you would probably opt the other way.
