347cid "BOSS" Block

[bye_bye_rice_boy]

Does anyone happen to know the max power rating for the BOSS 347 cid block???

I got mine for a '94 mustang GT convertible. Going to add AFR 185cc heads, GT40 lower intake to match blower, 90mm throttle body, 90mm MAF, Keith black hypereuretic pistons and rings, Kenne Bell 2.1L "Flowzilla" blower, and Meziere electric water pump . Will the boss block handle this??

Already have TKO 600 w/Fidanza Spec stage 3 clutch, FRPP alluminum driveshaft, and the rear-end is fortified with Strange 31-spline axles, Auburn Pro 31-Spline Diff, FRPP T/A cover, FRPP upper bushings, FRPP 3.73's. Suspension is in the works courtesy UPR. My #1 quesiton is-----what is the max rating that the boss 347 block can handle???

Any help would be greatly appreciated

It will take that and more from what I've read.

I read in one of the forums where a guy got 630 HP out of a 347. If I can find the article again I'll post it for you.
