Better acceleration?

With standard "rebuilder" pistons (I forget now the brand, may have been "sealed power") AND a 0.030 block shave my pistons on my 74 block are STILL 0.180" in the hole, I was pissed at that. With 0.70 more off the head, my engine measured out at exactly 8.4:1. When all the service manuals of the day claim they left the factory at that level.
If I'd have known that my pistons would top out that low in the hole I'd have had the block cut 0.100. that would still have put this engine with these pistons at 0.110 down.

But now you have the EXPERIENCE to see what we all talk about all the time about Chrysler engines is true. The blueprinted spec on compression was always lower than advertised. Usually, by a good bit. I remember the very FIRST one I blueprinted. It was a 70 340. I kept measuring over and over because I just KNEW I was gettin it wrong. So I called an older friend who worked at his family's machine shop and he came over and measured with me (I was 17) and he verified I was right and told me then none of the manufacturers engines ever measured up to spec and that most times, Chrysler was the worst out of them. But honestly, at a TRUE 8.4:1 and with the right camshaft, that engine should be pretty snappy.
