I'm using one to destroke a 400 to a 393 and it works just fine for me. The pistons are harder to find and a bit more pricey but I'm happy with the results.

Roadhazd, Not to argue with you, but if the cid is correct you have a 3 11/16
not a 3 9/16........Just to let other people out there know what is what......the 3 9/16 will make 360 cid....depending on bore of course.
Any motor can be build to run great and make power. each bore stroke combination has advantages and disadvantages......the best a person can do is understand what the advantages are for the rules and motors you run and use these advantages to your best.
As with any motor heads, cam, and intake make lots of power. I would rather have a 360 that had good heads and right cam before using a 406 that wasn't built with the right mix of parts.

Here's what I remember about my Chevy days.
350-.030 over with 9/16 stroker= 363 cu. in.
400-.030 over with 9/16 stroker= 386 cu. in.
400-.030 over with 5/8 stroker= 394 cu. in.
They are all good combo's, but I had better luck hooking up with 363. One thing to watch for when using offset ground stroker cranks, is to make sure whoever grinds the crank puts as much radius on journals as possible. If not you will have a 2 piece crank...I believe I still have some "souvenirs" out in the shop.

How are these motors compared to a 355 and a 377. I have heard alot about these engines but have seen one run that i know about.

Basically, all motors are air pumps. With the same cam, heads, intake, and carb the bigger air pump will make more power.[like Jeff replied in the above post] The question is... how much do you need for your track and tires. I've seen times when you need a 434, and later the same night a V-4 Wisconsin would be hard to hook up. I would consider track size and condition [at feature time] before deciding on how big of an air pump to build.

Good catch Mr. Awkward. I got my 5/8 and 9/16 mixed up.
