Just trying to educate myself before I start rebuilding my own big block for my '70 Satellite. Been reading a lot about stroker kits. I see that 440Source has stroker crank kits to stroke a 383 to a 438. So my question is, what's the difference between a 383 stroked to 438 and an original 440? Assuming everything else, heads, intake, exhaust is the same that is, is there still an advantage? A fellow who has many decades of experience with Mopar asked me the other night why I was wasting my time and money on a 383 and not a 440. He said that the 383 wouldn't be much of an upgrade from my 318. I was kind of dumbfounded on that comment. He's obviously a fan of the 440, but for heavens sake, there must be a difference between a 318 and a 383. For what it's worth, while the 383 will sit in front of a 727 for a couple of years, the goal is to go 4 speed, if that changes anything regarding 383 vs 440. Would love to hear comments not only on the stroke kit, but also on the 318 to 383 comparison. Have a great weekend all.
