Oil Filter Adaptor ??????

[DansBlown73Nordic]

I have this 454 im putting in a Flat Bottom. I have a oil cooler that I will be running later. I want to just put a filter adaptor on the motor to start it with.
I took a adaptor I had laying around and bolted it into my block. If I try to screw the filter on it will only catch one thread. It is way to short.
Do they make a longer one? They are both 454 blocks. One is two bolt and one is a four....Whats the DEAL????:confused:

Sounds like the adapter you have has been cut or modified, if you just want a stock one, go to your local parts store and get a new one. Take the one you are trying to use with you, and see if a new one is longer. Also your filter might be hitting the bolts that you used to attach the adapter. Sometimes you have to run a small hex head, sometimes allen socket heads are too deep.

I have matched the one I have up with a couple others. They are exactly the same....:confused: This has never been modified........:frown:

Call your "local" Chevrolet or GMC dealership and ask for Part# 3952301 - Oil Filter Adaptor.
Pretty much IF the dealership has been in business for more than 5 years, they will stock this part...
It should cost you about $25.00 + tax
By the way, are you using the "correct" oil filter????
I'm using an AC/Delco# PF35L Oil Filter on mine...

In a high HP deal I make my own, those factory cast dealios will break!..

Make your own??? I would be interested in seeing pictures of that.

One other thing I just thought of while reading your post again....mark IV have different filter adapters than the mark V blocks. The Mark V blocks have less threads on them than the IV blocks. Is it possible your trying to put a late model adapter on an early style block??

Ordered mine from Rex Marine last year when my stock one broke. Nice billet design. Heavy duty and not much more $....plus worth the security of having good parts.

The early MK IV blocks used a canister type oil filter and the later model spin on type (factory) adaptor won't work. Look for the sealing surface (block) to o ring (oil filter), and see if they line up. The early ones sealed around the outside lip of the block, with an o ring under the canister, later, smaller dia sealing surface, for the spin on filter. You can get an adaptor for spin on with the old block, but you should also check the fit of the future cooler before you go too far.........Moneypitt
