I built a guy a car a few years ago, a 69 belvedere, never weighed it, but it had full interior. 440, with a 496 440 source stroker kit, flat top pistons, 906 heads I hand ported, 1 7/8 headers, .590 lift Howards camshaft, don't remember the exact specs but it was around 240 @.50 duration, 108 center, 1050 dominator with a single plane intake, cheap ebay 3,000 stall converter, 4.30 gears, ran on pump gas, ran 7.00 all day long in the 1/8 mile, took it to a 1/4 mile track, it ran a 10.90 off the trailer, they told him to take it home no roll bar. He put a roll bar in it and ran it for several seasons before selling, he drove it on the street every now and then.
