well im just looking for your opinion on how to do it. i know the 6.7 stroker kit is 3200 for parts. then how much for machining? would you go that route or just supercharger or turbo charge it?

i know they also make a 426 stroker short block that sells for 4400. that makes around 5 or 550 hp. would that be cheaper then stroking one yourself?

stroker kits wether there for the 5.7 based 390-396 inch motors or the 420-431 inch motors based on the 6.1 block can be had cheaper than 3200...

depending on what level of power your after is what direction i would steer you in. what is the intended purpose ect.

ive played with some 640 crank hp 6.1 motors in the drag packs but i would say thats not very streetable...

mild to wild..there are combos out there.

ill pm you my price on stroker kits btw

If I had 7-10 Grand to spare, I'd supercharge. Edelbrock or Pro Charger.

supercharge

yeah i know the superchargers are nice. but for alot less i can turbo it and get over 600. has anyone seen the hemi that they turbocharged in hot rod mag? It was a junkyard motor and a home made turbo system and they still pulled 612 hp at 5500 rpm.
