What Engine?
 

This is the engine in my 1990 Supra Sunsport. Anyone have an idea what it is. I need to know so I can order Perfect Pass. Thanks guys.

My guess would be a PCM ford 351? Has the same firing order as an old Windsor 351. That engine was probably the most commonly used engine in the 80's up to the 90's. I think the 302HO has the same firing order, but think most of the boats back then used the 351W.

looks like a ford 302 to me. I think the firing order is different than the 351. Its in my PCM manual but I dont have it with me. If you go to correctcraftfan.com you can download the PCM manuals

Go to skidim.com they know all there is to know about pcm.

It is a 351 W 240 hp same as my 89 Sunsport.

Thanks for the help guys. It is really appreciated.

From what I can remember, without the book in front of me the "D" in PLD-PR-R12PP signifies 351/255 HP not 100% but I think that is what it is off the top of my head.

A sure fire way to tell 302 vs 351W is the width of the intake. The 351 is something like 10 inches and the 302 is going to be around 8?? I can't remember exactly. There are also reinforcing ribs on the 351 intake and around the distributor mount as it is taller, the 302 is almost flush. On a car it's easy to tell because of the location of the thermostat bolts.

Hope this helps

Thanks just in time. that is exactly what i was looking for!

you bet

Just think about how common that 240 horse engine was and how today we complain about anything less than 320.

I have been in a boat with 320 and it is a whole new world. Maybe next year i upgrade and play with the big kids.

if you're handy with a wrench, you could get a lot more ponies out of that 351. Dual plane intake manifold and a little head work would get you real close. Throw in a mild torque camshaft and your sittin on 300 horse plus. I'd estimate my 351w to be in the 330hp range.

Where I work porting and polishing heads is done on a daily basis. The thought has crossed my mind but I am just not sure i want to mess with such a good thing.
