well just to verify and vilify, you all got me thinking, and i plugged numbers into eap.
using stock stroke & bore (not likely), the small edelbrock al performer heads (there is a larger size), stock dual plane intake with engine heat, crane cam that specified 10-1 compression, 10.5-1 compression, peak tq was 474 at 4500, peak hp was 467 at 5500. this is conservative.
larger edelbrock head showed 483/472 with no other changes,
stock 428 cj head showed 462/450 with no other changes,
large valve 302 boss heads showed less power yet.
and jeez man, this is the 429/460 forum. if you had one of those you'd be making a ton of power! hah, take that all you fe-aphiles.
