That would be a 4-barrel ROCHESTER 4MV QUADRAJET CARBURETOR. Unless... It's an L78 (solid lifter, 375 HP 396) then it would most likely be a Holley 780.
L78 (solid lifter 375 HP 396) came with a Holley 780. All others had a Quadrajet.

250, 307, 350, 396/402, 454 CID.
Straight 6: 250. V8: 307, 350, 396 (actually a 402 in 1970) or 454.
I paid 3369.00 for a brand new SS 396 350 hp in December 1968
Depends on which 396 it is. The hydraulic cammed 396's (L34 and L35) got a quadrajet. The L78 (solid lifter cam) came with a Holley 780. The heads will also tell you which one, Oval port engines got the quadrajet and square port engines got the Holley.
The 1970 Chevelle SS had 4 engine options, ALL big blocks. The L34 was a 350 HP 396, the L78 was a 375 HP 396, the LS5 was a 360 HP 454 and the LS6 was a 450 HP 454. Note, these are the factory horsepower ratings. Also note in 1970 the 396 was bored out to 402 CID, but was still called a 396 for marketing reasons. The L34 was the base model engine, the other three engines were all optional for super sport models.
The 1970 Chevy Chevelle came with a 6 cylinder, all the way up to a 454 V8. If you have the 396 or 454 you need to use Premium Fuel. All other engines can run on Regular.
