283 power pack 520 head flow specs

[philB]

understand on the heads, been looking for a pair, ones I found are close to new ones, alum, but for the old engine to sound good, look good, and go down the road like the big guys with monster moters, and they all carry a 5 gal. can of gas in the trunk, I get to the weekend show and have choice of spots,
it's a lot of fun and if you want to go racing, I prefer to watch at cost it takes to run with um nowdays.
