So as the title suggests it's time to get power hungry
Current engine is the 392 6.4 hemi
Procharger do a nice bolt on kit good for 100 to 150hp so 630 ish should be nice
But to be safe I need a decent builder that understands the hemi blocks to fit the kit along with forged rods and pistons (drop in kit)
As it's questionable that the stock pistons can take the extra pressure
Not fussed on location I just want someone to fit and custom tune it all in

Dave Billadeau comes to mind or Pete Wiseman at Thunder Road? Way out of my league stuff but both are very good at what they do and are on here

I think I would use John Sleath, he has a well respected name as a builder & tuner. He has engine dyno & rolling road.
Dave Billadoo also uses John.

He also works on a lot of blown & turbo combos
