Well I really didn't get an answer to the question from the Forum but did find out from a mechanic.....
I can use a 5.0 roller block with original roller lifters and pushrods, 1965 vintage 289 heads, 68-75 302 dished pistons (not 5.0 flat tops) and the 289 timing cover. This will give me about 9:1 compression (or a tad lower) and all original A/C, P/S and Alternator brackets. Any aftermarket aluminum intake will do.
More horsepower, more efficient and it will still have the semi-stock appearance.
Thanks,
Ron
