This is an original GM aluminum intake for a Big Block Chevy engine with retangular port heads and a Holley carb. The casting number is 3963569. The 3963569 intake was designed to be used with the following applications: 1970 L78 396(402)/375HP,1970 LS6 454/450HP,and 1971 LS6 454/425HP engines. This intake was also used on GM crate engines like the LS6 and LS7. This is a real deal OEM GM intake. Don't miss this one.

This intake is in very good condition. This came to me with a GM LS6 crate engine from the 1970's. It is in bare aluminum finish with no paints or coatings. The part number and GM logo are intact and undisturbed as shown. All threads are in good condition. There is also no porting. The oil splash shield was removed from the underside at some point as shown and I see no date code.   This is an awesome factory high performance intake for your Big Block Chevy engine.

See my other listings for more parts from the LS6 454 crate engine described above including the standard bore 4 bolt main block, 6272990 rectangular port heads, 7416 forged crank, 7/16 dimple rods with TRW forged pistons, trap door oil pan, and more. I plan to list these parts as time allows so check back often.

This is your chance to own the real deal OEM GM 3963569 aluminum intake manifold you have been dreaming about at a GREAT PRICE. Don't Miss Out!
