manifold question

[Scamper]

I have an opportunity to buy to 360 manifolds. I cannot find anywhere to validate that they are 360 and that they will fit in an a/body.
these are the casting numbers if anyone can help.
The casting numbers are 4173186 and 4173158
They are well priced but I do not want to waste money.
Thanks

Scamper,

Sorry I can't offer any good feedback on the numbers you have. I've had a tough time finding information on 360 manifolds too. It would be nice if someone on the FABO site put together a list of stock manifolds for the various years of mopar 360 LA and magnum blocks (maybe it's already there and I just haven't found it). My understanding is the 318/340 manifolds can be used on the 360, but there is some small performance hit due to port match. I am not very knowledgable in this area, so I can't really say what the hit would be and if it would even be noticable on a daily driver. We need a Mopar exhaust professional to chime in here and tell the whole story for the 360 owners out there.

Good Luck,

I couldn't find any info so I passed on the manifolds. I will probably go with shorty headers since 340 manifolds are so expensive
Thanks
