B&M 174 bolts
The 174 I bought didn't have the blower to manifold bolts with it. It takes 4 bolts that I believe are supposed to be 7/16 x 7". Does anyone know if that is right? Also, I bought a crossover. What size belts will I need for the alt. and ps pump? Thanks

Chris,
For V-belts, I am using a Goodyear #15391 for the Alternator and a Goodyear #15525 for the Power Steering pump.
As far as the bolts go, can't remember if they are 7/16-14 or7/16-20. I went out and measured my setup (B&M 250). It appears that a 7" bolt would work. Mine are a "Grade 5" steel bolts. Dean Nickerson recommends one drop of red loctite (high strength), 3 threads up from the bottom of the bolt. An excessive amount can run down inside your intake and possibly cause some problems like getting in/on the valve seat. Dean has seen this happen.
No more than 10 ft/lbs. Doesn't seem like much but that is what the manual says.
You can always call the Holley Tech Line at 270-781-9741 or Dean at 215-781-1370.
Good Luck!

Thanks Russ. I'm pretty sure they are 7/16-14. The guy I bough it from did send one 7/16-14 hex bolt that is only one inch long. It looks like it will fit the back side of the blower.
