pro-boss in a mustang?

Motor mounts will likely be different. Outlets on the risers will be in a different location and larger (3.5" vs. 3").

The biggest thing is the rotation difference... that Pro Boss is most likely a LH engine, which would spin a RH prop only when mated to a PCM 1.23:1 tranny. It sounds like that isnt included? If mating to the BW, you'd need a LH prop and that opens a whole different can of worms in terms of the boat's performance and handling. Get a serial number off the engine to confirm.

Is the Pro Boss carb'd or EFI? If EFI, is it TBI or Multiport? If the latter, the fuel system is a little different and would require some additional plumbing.

It's a 95 multiport gt 40 with computer. Would not be the dumbest thing I ever did but it sounds easier if he had the trans. Could just reverse the linkage and run i in reverse...

the answer is no you can not reverse the linkage and run it in reverse. The transmission does not have strong enough internals on the reverse side to handle full loading. You can index the pump on the trans so that it works with a LH engine but it will always turn the prop the same direction the engine turns while in forward. The price of the pcm transmission may not be a deal a breaker but it does let in a few other costs like a prop change, driveshaft mod, etc.

It is a doable swap though.

If you decide to pass on the engine however let me know where it is as I have a 95 that could use an engine for the right price.

Your exactly right Eric, that would be logical and cheap to replace the 307 with a 350 and get the most bang for the buck. I however an a die hard ford guy and always wanted to have a ford motor in my mustang. It sounds like it would be easier to find a 351 donor boat of the same era and put the gt40 heads and intake setup on it if I really wanted to go that route. I probably ought to pass right now though, I need to finish the wifes boat this winter and get things off my list and the old mustang is not in dire need of the upgrade right now.

http://toledo.craigslist.org/boa/2719530494.html here is the listing on craigslist. everything there including the computer. I wonder agbout the scored piston with that low of hours, injector go bad? I found it while trying to run down some GT40 heads and intake for my wifes 90 mustang convertable. I can pick up heads anywhere though. Have at it Guys if you need it. Stryker is just a couple miles down the road from me just off the ohio toll road.

all your jingle jingle will bolt right onto a 350 or 5.7
its the extras that always kill you when you go from a 36c cup to a 32 a, new bra, shirts, ego

Yea, thats the only reason I was considering it.

Geez, I wish I lived in Ohio...

I think he wants to go up Eric not down

just got a complete 5.7, doing a comp test today, low hours
its a volvo, you can pull the jingle, e-bay it and re-coup your doe
manifolds, pumps, brackets

Careful! No such thing as a RH roller cam for a Ford 351w- so if you want to stay with a RH engine and all its wonderment, then you'll either need to 1)pony up big bucks (~$800-1000) for a custom RH roller cam (not including conversion parts, such as tie bar lifters), or 2)stick with flat tappet. Of course, you could keep the RH prop by mating a LH engine to a 1.23 trans, but thats not cheap either ($1700 from SkiDIM).

If putting a Chevy in where a Ford once was, you'll need to play with the mounts a bit as well.

My vote would be to build a RH bowtie powerplant for it... I know of someone who is putting in a RH 383 stroker in place of the original 307, and reusing all the accesssories. Id be doing the same!

just put the camera in the holes, looks good,
man i get alot of engines...............................they are on the garage floor for a reason, i pulled the block plugs and anti freeze came out.

IF it is a roller gt40 motor I would be tempted to take the reverse rotating assembly out ot the 79 and plant it in the newer block essentially making it a reverse rotation pro-boos minus the injection at this point.I have not done all the homework yet but my hunch is most of the internals will be interchangeable, sometimes I ran into internal or external balance issues but 79 may be new enough to be the same.

Its not that simple. The rotating assembly could be switched from LH to RH- its the rear main seal thats rotation specific on a later 351w. The cam is also rotation specific- and like I said, RH roller cams arent off-the-shelf items like the RH flat tappets. Other accessories are also rotation specific- like the starter, and distributor (gear).

The 79 is out of a nautique, the crank, cam gear and distributor are all reverse rotation. the crank should have the reverse direction wipers built in and the newer block might not have oil wipers. you saying that wont work in the newer block to reverse the rotation? Im not following yet. I realize you cant just switch rotation without changing the cam components and timming. It used to be the cranks had to be swapped as well due to the oil wiper groove direction.

The roller tappet thing is not really an issue either, A guy should really use the 79 marine block anyway, whole bottom end so you dont need to convert an automotive block over. just use the gt40 top end. reverse rotation roller cams could be a special order thing$$$. I love flat lifters, used them all my life

The point is that no matter what you are trying to do it certainly can be done. With the exception that a reverse rotation roller cam would be very expensive for a sbf at this point. Although you would only need the Tie bar lifters if the late model engine you had was not roller equipped to begin with. Which sadly I do not belive the lightning engines ever were (conjecture was that it was not worth tooling the roller blanks for the higher lift/duration that the lightning had for the low volume so they continued to used flat tappet setups in the late model roller capable blocks) but as Jody states some 351ws in the last years of production were.. i have found the best bet to be broncos or f250's... f 150's seem to be hit and miss even to the end of the production run.

I called the guy with the GT40 a couple days ago... he has a buddy that maybe interested if he can find the cash. If not I will be running through your neighborhood on a procurement mission in the near future.   

having re read that I think I was confusing... the lightning block if late model certainly could be converted to factory style rollers even though it did not come with them. However, by the time you buy the factory style lifters, dogbones, and spider and then drill and tap the block a good set of tie bars while still more expensive would not necessarily be a bad ideal.
