is it bad

[Cj Ford]

that my 400 in my Bronco is smoking more then my powerstroke can....

went on a couple wheeling trips recently and on the last one I did some internal damage..I either broke a ring or cracked a piston as far as I can tell. It sits at idle and puffs blue smoke and if you rev it up it will smoke enough that you can not see my garage or the bronco... Im goin to try and get a video of it as I find it funny

anyway I picked up a 351M donor motor today out of a 79 F150 and will throw it in this weekend if I have time, the plan is to make the rest of summer with the used engine and during the summer I am goin to build up the 400 that is in the bronco right now and put it in during the Christmas holiday.

I knew it was coming, I already picked up a Edelbrock performer 400 intake for the build and am goin to order cam, lifters, rings, pistons, bearings, double roller timing chain, oil pump, new pick up tube and a complete gasket set. I plan to get the machine work done to the block and have them go through the heads do a valve job, guides, springs then bring it all home assemble it

my mule donor on the trailer today, its a total drop in mounts fuel pump carb manifolds it has 78,000 original miles and purrs like a kitten just thought id share

Nice! sorry to hear but looks like you got it all figured out.

[Cj Ford]

ya I cant wait to open up the 400 and see what let go ..I hope it didnt hurt the block or crank

[rock hardson]

You need a 351 Clevland or 351 Windsor. Those things are beasts

[Cj Ford]

I dont want to change out the tranny and go with a 351W, if I was to do a conversion I would drop a 460 in

[blowinsmoke4life]

a 460 would be beasty

[ford_trck]

Do the 460 that would be sweet. I don't think it would stay stock though, bore it and stroke it to say maybe 530 cu in and then maybe you will be happy

screw all that...

400M block
400M crank
Chrysler small block 6.12in rods
Chrysler 340 pistons.

comes out to around 427ci.

Add on:

351C 4bbl quench port heads
351C 4bbl manifold (torqer series or RPM)
weiland 1in manifold adaptors for 351C to 400M
MSD 351C/351M/400M/460 distrib.
MSD 6al w/coil
Jacob wires
750cfm vac secondary carb

Cam specs will vary, I used a solid roller that was very aggressive on my last build like this. I had WELL over 500hp before the nitrous. Once I move to a EFI setup, I was around 600hp. In a truck, use a RV pattern cam, keep the power band from idle-5500rpm, use a fluidampr, upgrade your oiling, and don't use headers. This will put out some SERIOUS torque. You'll be snapping shafts if you aren't careful.

Very, very interesting combination.

429/460 has same bell housing as your 400M. I put a (10:1) 429 out of a T-Bird in a Bronco & found it quite good. I used Offy Dual-port, CompCam 268H, Rhoads lifters, MSD, and headers. Better mileage than the 351M that came out, and pulled a lot harder.
