I have no personal info on them But for a stroker I would buy it as a kit.. With parts known to work together

I bought a 440 to 528 stroker kit...plus aluminum caps with a girdle and serp belt kit. Everything looked great and went together well, will be starting it up in the next two weeks but search some threads, many buy from 440 source, most thiings are good, some not so much. But stroker kits get nothing but good reviews.

I have bought from them before and have both good and bad experiences. Can probably find the full story on here, but the bad experience was with a water pump housing, AC wouldn't fit, called them and they were trying to tell me I didn't want to have AC. I bought the adjustable rocker arms, good product, and am very happy. Just do your research.

I have a 440Source kit in my 493 which everything has been fine. The only issue I had was the piston pins were a tad tight in the rods. No big deal as I like to fit the pins myself which I did. I used a brake cyl hone to hone the rod bushing to the size I needed. No big deal. I just twisted it to 6400 this weekend running 10.70's. Ron
