Denny,

Here's what I came up with:

XE262H - Couldn't find the specs
X4270-11, 34-239-4, 451hp@ 5000, 548ft-lbs@3500
275DEH, 34-330-4, 485@5000, 562@3500
270H, 34-229-4, 430@5000, 549@3000
280H,34-331-4, 456@5000, 535@3500
292H, 34-336-4, 466@5500, 512@4000

These are all with 11-1 compression, edelbrock heads, dual plane manifold, 870cfm carb and large tube headers with mufflers.
