[slowtech]

Does anyone know of a source for chev 454 exhaust manifolds for motorhomes. Any help would be great. Thanks, Tom.

I may have a pair. Will check in the morning and post. Ok? I know that at one time I had a pair around here in storage.

try dorman #'s 674-159 and 674-244. i did a quick search and used an 1985 cab and chassis. the manifolds are readily available. another source i've used is "steven's exhaust manifolds" i got the # in a "motor age" magazine. when i'm doing a job like this i have an exhaust bender that makes it so much easier to adapt.

I have also used Steven's, their number is 1-800-443-2673. They have always worked well for me.

Thanks for the info, I'll check'em out. Tom.

I have a set of used ones that have the air injection tubes in them. You can have them for $50 a piece plus shipping. If you are interested pm me and we'll get together on it.

sold?

I still have them.

I remember seeing a two piece manifold for these that allowed for the massive expansion and contraction on these applications. Can't remember where, but somewhere........

Ain't not ever heard of split manifolds for a 454. If you can, post the company name that makes them.

if your idea of "popping a few pills" is vitamins, calcium, and you spike your "o.j." with metamusil your there. it's amazing how we perceive old. when i was 10, 20 was old. now as far as this manifold issue goes i remember the flex joints in the manifolds. i seem to remember them in front wheel drive vehicles more than others. i also remember taking them out in pieces and for the life of me can't remember the applications. i would go on line and look at the dorman line or contact stevens and see if they have an on line catalogue. for years any time i remove a manifold or replace one i oversize the bolt holes a bit. don't use stainless steel or anything above grade 8 bolts. make sure that the bolts don't bottom out. i see many applications that the bolt is bottomed out, does the job for a while and then snaps. as we all know bottomed out usually means it stays but if it isn't a left hand drill bit takes it out. dorman usually includes installation kits and are worth their weight in gold. i remember some older applications didn't use gaskets. it's my understanding the reason for this was the expansion issue. if they don't call for gaskets then i don't install them.

Let's see here now. Is there any chance that steve has reached the definition of "old"? Does he take pills, vitamins, etc?

Steve, tell them the story about the time you and Virginia were going to the concert....
