Good News! I got the old 99 breathing fire, I need to tune it a liitle yet, but once it's warmed up, it runs pretty good, and I don't have access to a dyno, and it doesn't have a pto for that anyway. What the problem was, the previous owner who must've dug into it years ago put the flywheel on a bolt off, so my timing marks were off!!! Lots of frustration and empty beer cans after that one- ha ha. Well guys, I would like to thank everyone for all the help and thank Kenny Grimm for the valve I needed for it, now, I run into another problem...... a factory side of the block mounted sediment bowl..... I've been looking but can't find one. Anyone know of one? And, how do these old 4 cylinder 99's pull? Mine is putting out 493 cubes with the MandW kit in it, but also how do I bump up the r's a little? Thanks
