D17 stroker build

[blue924.9]

Lost our local pulling association where my mild 240 inch engine was competitive. Next closest association my suitcase weights require me to pull up 1 more division and I have some heftier competition. A couple years back I bought a wd for parts that has a series 4 d17 engine in it, but it’s locked up. I’m thinking it’s about time to research building a hotter engine, who does stroker cranks these days? I have seen the name Dan Karpel used recently with positive feedback. Anyone else? I’m not looking to push the edge of extreme performance or pay top dollar. In would like something in can build and run for years reliably. I’m not real experienced with big cube Allis engines maybe what I’m looking for doesn’t exist either lol.

I would also be open to suggestions on build recipes or already built engines for sale

You can get 5” of stroke out of a D17 engine, but I don’t know who does it.

Building a puller and getting years of reliability are 2 different things.

That would be 251cu” instead of 226 which could’ve up to 70HP , up from 63HP.
Have to add some cam , compression , port cleanup , dry air cleaner etc .

The one I actually seen the inside of with 5” stroke had also been bored out to 4.25”. That would make the cubes 283.

Also had high compression and cam work. Don’t know what it dynoed but I’ve seen it pull and was stout. How I saw the inside was the owner blew a head gasket and was looking for somebody to replace it. I took on the job cheap because I wanted to see what was inside.

Can do a 5" crankshaft with stock rods and pistons.
