I just got off the phone with a friend of a friend and he wants me to build him a 408 Windsor for his 91 full size Bronco. His 351 has a rod knocking and is getting read to die. What is the deal with a 408? It has been 20 years since I played with a ford motor much less a small block. Any good URLs for info/Parts??? TIA

You can buy complete brand new stroker shortblocks directly from Ford Racing (used to be called Ford Motorsports). Prices seem pretty competitive. They also have stroker cranks available separately.

Now were getting some were. What is a 408 and are the heads off of a 91 351w going to work?

Aren't the 400 main bearing journals larger than the 351W?


Old Scout check these links. It's a 392 but that may be close enough.

A 408 is 4.030 bore x 4.0 stroke.

The bonus part is that it is all brand new and spin tested before it leaves Ford. <IMG SRC="smilies/glasses.gif" border="0">

The 351w uses the same size mains as the 351/400 mod. I think you have to get the rods cut, or its the block. Its been a long time since I looked into it. But the SVO is a great way to go. No guess work!

Um...actually, they make a **great** street motor. Been running a 423 (only went .040" over on the bore) for four years now, and I drag it every year too. I also wheel it in the rocks every chance I get. Why is it a great street motor? Very docile idle (sounds only mildly rumpity, with a fairly stiff cam in it, due to the extra cubes which tend to calm it down), BUTTLOADS of torque, peaks at about 5,000rpm (this cam, anyway), no worse heating probs than stock, very reliable, has **very** quick revving due to lighter weight rotating mass, etc., etc. Again...in my opinion after running one for years....very good choice for a strong street motor.

Might I strongly suggest putting in a roller cam? It goes a very long way towards driveability and a broader torque curve, as well as fuel mileage. You'll get more HP and torque across the board without having to go to a cam that doesn't idle well. I ran mine with both a nonroller and a roller cam, and I'd heartily recommend going with a roller cam. FWIW, my cam is a 220/[email protected]" duration roller cam. Below are the sims of the exact same stroker motor dyno charts with the old flat tappet cam vs the new roller cam if interested.

Well, engines are one area I have yet to mess with. The 351W in my 94 Bronco has got 110000 miles on it and still runs great, but I don't expect it to last forever. It seems that most built engines are running carbs. I guess I'm spoiled and don't want to start messing with carbs. You can do a stroker with fuel injection can't you?

Yes, the stroker 423 I'm running is multiport SEFI injected, not carbed. I like it that way muuuuch better than carbed. No worries.
