My 70 bird project. 454 with billet specialties pulleys will it work??

[NASTY-LSX]

this is my 70 bird. Im pulling the built pontiac 350 to install a GEN6 454 with a T56 MAGNUM 6 speed. Car is a frame off restore. only thing left is body and paint. I have all new interior to install. Yea sure I could have gone LS, but im trying to stay a little old school with this. Sure I could put a 455 behind a T56 MAGNUM but cost for a 455 is crazy money, then the cost for the build is crazy money. I already have the 454 so there is no going back.








Dont mind the upper RAD hose, it was temporary.
I have read some NEGATIVE about BILLET SPECIALTIES pulleys on 2nd gen F-body cars. Only the P/S pulley hits the gear box. This is the only NEGATIVE i could find.
Has anyone here put 1 in there 2 gen F-body?? did you have the same problem? I already bought it, but have not installed it.

this is the kit i bought.
