New to the forum here.

'm currently having my 454 upgraded with a 525 sc Weiand 177 but it did not come with the intake manifold. The builder tells me that the intakes available almost everywhere for a 177 blower to a BBC wont fit and it has to be a Merc part which is discontinued. I'm hoping someone can shed some light on this or maybe someone has this intake and is swilling to part with it. ANY help is great appreciated!

I have 454's will 177's with regular intake manifold. Not sure what the difference is between the merc and regular. Maybe thermostat location?

I think what he meant to say is manifolds for a 174 blower wont fit on a 177 blower. The way the blowers mount to the manifolds is different

Ah yes, dosen't the 174 bolt on the outside corners?

I think he is having a problem with the thermostat housing... the chiller in the pik above is one way to fix that lol

I have some I’ll be listing for sale in the next week or two, problem solved haha.

Victory marine in Dickinson Tx had a brand new one in the box back a few months ago.
