Came up in a different post about B'n an A-body. Realizing that the head flow number is pretty much the benchmark on what a moter can produce HP wise, I brought up the fact that the LA 915 J head with a 2.02 intake (stock stuff) outflows the B's 915 head with its 2.08 intake at the same .500 lift at 26 inches. The stroke of a 360 is longer than the 383's with only the 4.25 bore of the 383 eclipsing the 4.00 bore of the 360. Take in the weight penalty of the 383 and the small header selection of the B'd A engine bay and I say a 340/360 is a better choice in an A on multiple fronts. Take an honest look at the stock numbers on a 383 and a 340 (360 with large valve heads) just to keep the max effort builds out of the debate and the cost factor of a core 360 over a 383 today and i gotta ask is the 383 worth what it gives you...which is...? Let the debate begin. Try to back up data if you throw out numbers. I looked at Hughes website for flow numbers of stock heads and am not sure if their numbers were their results of bowl work or off the block tests. 915 A head was 20 cfm over the 906/915 B head at .500
