It worked out to 7.6 to 1 according to this chart --->http://www.wallaceracing.com/head1.htm . People forget that low compression was all they had in the 50's, and all the go fast stuff like multiple carbs, milled heads, "3/4 race cams",and fast timing was what worked on garden variety motors. Sure high compression is better, but not unless you have the high octane gas to survive, or an engine managment system to adjust the timing on the fly. Gears were 3:23 and I used a 3:11 first gear Saginaw 4 speed transmission. So my overall gear ratio was a sweet 10.05 to 1. With an overall ratio like that you never need to ride the clutch to get going, you just- GO! Totally stock short block out of a GTO w/60 lb Melling oil pump and the heads I got at the Englishtown swap meet from a guy with a dozen or so sets all redone with fresh valve jobs. I saw 6-X and grabbed them. I actually got 16 mpg highway on rat-piss gas.
This deal either got sweeter or something isn't right. He got back to me on the heads and they're 66's. Those came on the 325hp 455's. I asked him to get me the block casting to and I'll see exactly what we have here.
Maybe it's a 455? I have set of the 72' 7M5's, from a 455, same specs. Low compression, big valves, pressed in studs. On a 400 they would be such low compression you could burn stale beer.

Only problem is beer doesn't sit around my place long enough to get stale :lol:
Block is a '70 9799140.
Heads are 96's. According to what I found they're from a '71 400 w 96cc's.
He said it ran great and pulled it because the '69 Grand Prix it was in fell apart. Has a 4 bbl intake & no carb.
$300 and going to check it out.

It's only a couple hours this time.
Last time it was 6 one way! You can't really find much in or around the city that hasn't been totally beat to hell anyway.

Looks like I'm going to pass on this one and just forge ahead with the 455. It has broken manifold studs in the heads and is rusty enough to be an engine fossil. If he wanted less it would be worth it. Besides it's money better spent else where.....like rods.
