The best stroker 408-416-426-435 combination in stock 68 340 block

The biggest thing I see with these strokers (the first Chrysler I did in 1999) was that they are way out of head. The lower R/S ratio makes it worse. Even at a 3.58 stroke it's hard to get enough port area. Anything over that and a W-2 is almost a must if you want to make power.


It may just be that I'm dumber than most (my wife would agree) but I've actually made power at 8000 and up and it's freaking hard to do. And I was doing it on 345 inches with W-2 and W-5 heads. To add 60 plus inches and reduce the R/S ratio changes everything when the port area is too small.

That first stroker I did made 565 HP and some stupid amount of torque (which I really didn't care about) but it did it all by 5200. Even if it still made 565 HP but did it at a paultry 6200, which isn't much any more the thing would have been much quicker.

There is such a thing as too much of a good thing. Certainly stroke is one of those. It fashionable to say you have a 4 inch stroke but that's a lot like ***** length. Unless you are doing ****, it's just bragging.
