probable 408 f1c set up Currently i have a 408 that was built awhile back and its a pretty high compression. So anyways it has a rod knock now and its about to get sent out to the shop for a rebuild.. So my boy is convincing me to lower comp and to go boost with a f1c procharger... What are people pulling with these type of set up. .. Im really liking the idea of going boost
Your buddy is right. If you go the Procharger route, you don't want to run very high compression. What compression is your 408 at now? If it's not too high, you can always run e85 or meth (or both) to help out, but sounds like your going to need new internals anyway, so shoot for a compression between 8.5:1 and 9.5:1. The F1C Procharger will make a ton of power and should work really well on a 408.

Yea i know lol.. My original build was for nitrous but like i said my boy is convincing me to go boost since im gonna have my engine rebuilt.. What would be some good internals that would be able to handle the f1c .. Would i be able to get away with the standard callie stuff or would i need higher end parts.?

Don't see why the Callies stuff wouldn't work just fine. Check around on here for similar combos. Carlos os doing a F series Procharger on a 408 right now. Might want to check out his thread or PM him and see what his setup consists of.

hasnt some of the callies dragonslayers snapped at the crank snout? How much is lunati pro series up to par with the callies?
I think that was due to people tightening the belt to prevent the supercharger from slipping and putting to much stress on the snout and I don't think it was limited to Callies. I'm building a 408 with a 6-71 and plan on running a Callies Compstar with a crank support.
Our shop has pushed stock bottom end engines in our own vehicles to some pretty hard limits and never popped one. I've personally been 6.10@114 in the 1/8th on a 250 shot when my combo was cam only and my boss Jonathan has been 5.90's@116 on a 225 shot when his combo was cam only as well.
My opinion and our opinion at our shop is keep SBE's at 700rwhp or less for longevity.

700rwhp is absolutely achievable with a 408. I'm rebuilding a 408 that made over 850hp at the crank on 9psi and that was with a 10-71 roots blower on e85. It was on a 925hp+ pull at only 5200rpm pull when it broke due to a dyno operator error, It should have been at or above 1000hp at the crank.
