393 Windsor vs 408 Windsor

I am looking for some info on strokers for the 351 Windsor. I am going to rebuild one and I am looking for the advantages and disadvantages of both.

I think that the 393 is a 3.85 crank with stock rods and 302 pistons. I also know that the 408 with 6.2 rods intersects the oil ring. How bad is this if at all.

This will be a torque motor for an off road truck, no real high rpms. I am not sure what heads I am going to put on it yet. I have a c9 set of heads, but was thinking that I would be better off with aftermarket heads. I have also thought about just a rebuilt 351 and spending my money on the heads, but a few of these strokers are quite reasonably priced.

Any help or advice is appreciated.

Horsepower would be 350 - 400. Good torque down low.

I have two 74 blocks that I can use.

I think I would go for the 392 as getting the piston pin up in the ring lands can be some trouble..specially if one is thinking of reliability..

Check into the Clevor head modification as one can use the 2v style heads and get a significant gain in breathing and if you can find a ford specialist to build your engine that would be good..

Other wise a set of Roush heads I have found are about the best financially as they come out of the box all done and ready to go..

Of course if you have your own machine shop then you can build a good set of heads for a reasonable price..

Can dynamics up in colorado are a good source of ford cams as they specialize in ford cam and valve train..

About all I can think of right now..

You're right about the 393.....but with the correct piston, there's not an issue with a 408.

I'm building one now with a SCAT 4.0 stroker crank, 6.2 rods and Probe pistons.

Aftermarket heads would most certainly outperform a set of stock C9OE 351W heads in almost all cases.

I bought my heads and stroker kit from Brian at www.adperformance.com

Lots of stroker knowledge, good pricing and excellent customer service.

Good luck!

the 393 is up to the task, no need to go with the longer rod 408, you will want to balance the assembly, you will need some portwork on the heads, the exhaust needs alot of help especialy with a stroker, the rest is pretty straight forward, the heads need the attention.. if your interested I can get affordable aftermarket castings, I will not quote the price on the board but youd be surprised how affordable they are, not to mention light years better than factory heads.. and it would be a bolt on affair no need for any portwork.. just a thought, and im not trying to sell anything, simply stating whats available..
