Fram CA326. You can check other mfg. equivalents at your local parts store or maybe on-line.

BTW, this is using the stock filter base and lid.

 

Thanks 73 Shark, I'll stop by the auto store in a few days. I have a stock carb, manifold and air cleaner. How about the screw for the wingnut, will I need a longer one?
Reguarding the engine I got GM's 10067353. They call it the "Universal 350". It comes with a 3 year, 50,000 mile warranty, 240 HP. I've put 26,000 miles on it in 5 years and it runs just fine for me. PG

 

Yes you will need a longer stud. The stock one has 1/4-20 thread on both ends, so I bought a piece of threaded rod and cut it off 1" longer than stock. Works like a champ.

What are the specs on the "Universal 350"?

 

4 bolt main block with 2 piece rear main seal.
Cast iron crank
LT/LT4 powered metal connecting rods.
Cast pistons (dished.)
Hydraulic flat tappet cam. (.383" intake/ .401 exhaust) and a 112-degree lobe seperation.
Cast iron heads with a 75cc combustion chamber
8.5:1 compression
GM claims 260hp and 350 pounds of torque with a 4 barrel and headers.
I cost about $1,600.00 and every thing bolted up in the same place with no mods. I kept the cast exhaust manifold and ran chambered exhaust under the car. It sounds faster than it is. PG.
