Trying to understand options and discovered ATK’s 408 stroker short block. Looks to have decent internals Scat and such.

Anyone have any experience With these?

Running a Blue Print 408 in my car and I'm very happy with it.

I considered going the same route.. I think there’s two levels of short block..I think the difference is the rod choice. They’re 5.9 magnum based and I think those are balanced internally. I ended up finding a 340 though so I went that route instead. One of them was $2999 through summit… at least earlier this year it was.

Yes. I am also considering a Blueprint.

I'm very happy with mine bought a turn key from them back in 2019 and never a problem after 15,000 miles. Long 1,200 mile runs is no problem.

Nope, according to the website the difference is the more expensive short block has a forged crankshaft and forged pistons.
