It's going to take more info than that to answer your question. How do you know it's a 5.7? If you have no idea of what year or model number the engine is, find the GM block casting number on the block.

Any chevy 5.0 or 5.7 of the same vintage will get you an oil filter.

sorry forgot to say, well i was told it was a 5.7 1991 model but i will look for this number on engine, where would it be stamped on the block?

Ayuh,.... It's a 350 Chevy,...
It uses the marine sparkplugs, AC Delco, MR43T...

An oil filter can be found at any parts house,...
SBCs use 1 of 3 filters, short, mid-length, 'n the tall 1...
Use whichever ya got room for,...
Most use the short 1...


edit;,hmmm,... Startin' a post, 'n finishin' it 45 minutes later, really changes the conversation yer joinin' sometimes,don't it,..??

Nope, that's the automotive steel bodied plugs...
The "M" is for marine, their an Alloy bodied plug that don't rust in easily...

cool thanks for that.
last question. are the filters and plugs the same as the mercruiser? cause the local marine mechanic says he has never got stuff for volvos but he has the service parts for the mercruiser. can i ask him for the early mercruiser service items?

Yes, the spark plugs and original oil filters are in/on the engine when Volvo and Mercruiser receive the long blocks from GM.
MR43T is what GM puts in them, NOT CR43TS (no S)

part number for a oil filter?

Re: what plug

Tell your dealer it's the same as a Merc 5.7. I don't know what the part number is right off. They change constantly.
