2 Coils w a damper, If I remember right it was .3 w piston @ the top of the hole plus whatever the plane job did. But I'll check it agian tomorrow. Cam is 525/532 lift 292/305 dur. Way too much cam for 8.2 and still too much for 9.0. Something in the 280's would be better. I think but its what I have. The springs are right as are the matched Hyd. lifters. Those KB's (KB202-30's) have a DEEEEP valve slot. More clearence then needed roughly .045+ but I'll clay them w/o a HG B4 assembly, block and heads are planed and dead flat. A bud on another site and I worked out what I needed to plane off to get what I wanted. But after a computer crash I no longer have the details. I just wrote down what I needed ro do then BOOM! No computer for a few days. When I got back on everything but what I had written on paper was gone including links. Hard to say how much I lost in CC's w/o ccing them and thats not going to happen in a MN winter w no garage heat.
If I remember right we had it figured at .048 less than b4 w the 020 HG and
.030 off the headsLast edited by Dgas56; 12-20-2009 at 06:55 PM.

Thanks guys! It's been a long road. Fun doing finishing work for sure. Getting the dash ready for paint and some interior trim. Have to do some finish work on the aluminum headliner before...
