Mopars 402 stroker shortblock

Hi all,
Trying to figure which way to build a 360 engine for my duster. So much has changed in 21 years. Was looking at Mopars site and noticed a 402 A block stroker short block part#5007840 on their site.Not any info there. Looked at Summit and found that their 020 over on the bore,cast crank,cast pistons,NO compression ratio listed.
Has anyone bought one of these? Ideas?


thanks OG
