I still run a 4" stroke in my '87 with boost (0.030 over, 408cid). The block is half-filled, not because it hit water with clearancing, but moreover because of the extreme loads associated with high boost.
These long stroke motors will last a long time when built properly.

Just looking at some different things to do with the basics of what I already have. I've considered just selling my current motor, top to bottom, and starting with something new.
Hey, who wants to buy a nice 383!!!

If you start with that new block it is designed for Hyd Roller lifters. So keep that in mind when you design the build around the new block. If you stay with the TPI you could build a 400HP 500ftTQ monster that would have folks thinking you have a BBC underhood.

If I built that, I'd be going backwards. I'm right at 500 hp now.

And for some of us there is value in the long block appearing stock.
My engine still appears to be a factory block (which some might think is 350 CID), and the heads appear to be factory aluminum (special work done to raise the valve covers to clear the Jexel shafts).
This is why you would put a 4" (or more) stroke in a factory block. All appears fairly stock. Until you start it...

Yes, actually it does. I'm kinda surprised you don't see more guys using it. I'm waiting on the shop that did my current short block, he may have a 406 short block that I'm interested in. Thanks for all the input.
