We are super stoked to have found this 72 Gran Torino Sport that's been sitting in a barn for 25 years.  Body is fairly clean but we'll be rebuilding it from ground up.  This is a project car with our 16 yr. old son.  I've been doing a lot reading the last couple of months (just signed up this forum and it's a great find!)and I'm wondering what you think about rebuilding the 400 or swapping for a 351C?

Thanks for the input!

A 400 is a great motor, especially if you're rebuilding it since you can correct some of the shortfallings from the factory, the down side is that there isn't quite the parts selection for the 400 as there is for the 351c.

I'm all for keeping the original engine in a car but have always been a
huge fan of the 351C-4V. Also, they've been getting a bad rap lately so we should build as many as we can !!! Anywhere up to 500HP is easily attainable. If you read up on the 400 one of the few drawbacks is the deck height & what type of heads are available. As torkair says, 400 parts are hard to find, as it is the Clevelands are tough to locate parts for as well because everyone is building Windsors.

both of you guys echo my thoughts exactly.......I like the idea of having the original motor but I keep reading such great things about the performance possibilities of the 351C.  I've researched a 351C crate motor but really don't want to spend the dough it would take to get what I want.  Clearly there is more affinity out there for the 351C than for the 400 but I've also read some good things about the 400.  Since it's been sitting for so long I have no idea what it's going to look like internally.  Our current plan is to pull the engine and tranny, have the tranny refurbished (C6), breakdown the motor and see what it looks like and then decide from there.  I really just want to make the best call between the two motors so we get it right the first time.  Thanks a ton for your feedback!

You might want to wait on the trans rebuild until you decide what engine gets the go ahead. If you switch to the 351, the trans is different along with the motor mounts and a few other items. An easy switch all depends on if you can find a complete donor setup for the change to a 351.
 
I had a lot of fun with my 400 before switching to a 460, but I've built some good running 351C's also. It all comes down to what the goal and budget is. Good luck and don't be afraid to ask questions, this site has a lot of info.

The 400 is, in essence, just a bigger Cleveland.  Heads and valve train are a direct swap as are connecting rods and cam shafts.  Really the only things that won't swap are intakes, pistons, and cranks.  The intake is an easy fix as there are spacer plated that allow you to run a 351c intake on a 400 block.  Then there's the crank and pistons, if you're crank is toast then you can order a 4" stroker crank for a 351w which will have the correct main and rod journals but the added benefit of being much lighter than the factory piece.  The Cleveland pistons won't work because they sit too far below the deck to be useable but a machinest by the name of Tim Meyers makes some really nice forged pistons for the 400 for about the cost of some off the shelf slugs, or save yourself some headache and get a 434 stroker kit from Tim which really saves a lof of guess work with the bottom end of the motor.

Thanks Skinny and torkair......good idea to do things in the right order....We're a remodeling contractor so I totally understand that concept!  This is our fist big project car so I really value this input......I did find Tim's website and an am planning on using it.  Because this is our first one, I really like the idea of staying with the 400 so we don't have to make a bunch of mods to make things work.....and I also like the idea of the 434 stroker.

And if you do the same build on a 400 you've got an extra 51 cubes of cool, lol.

Thanks Fortified.  Looks like a great site.  I tried to sign up but the link is not working.  I read through some of it I think it will be helpful.
