Wow do these forums load slowly!


Thanks for the offer Duane! I have a guy in my club who got in touch with an obsolete GM parts guy in the Northwest who might have the correct part number for me. My toes are crossed. Why Buick let these blocks out the door is beyond me...I talked to Crane Cams, and their helpful suggestion was 1) Bush the block or 2) throw away the block. Gee, thanks, and I'll buy your products why, exactly, Mr. Crane Helpguy?

Your offer is very kind but my reserve plan is to get two FSB lifters, and cut one in half, and then take one of my old GM stock lifters and cut it in half, and compare side wall thickness. A custom or adjustable pushrod should do the rest if I can't get this GM part and the FSB lifter can actually be machined down. I trust this guy in my club, but I also suspect he had his lifter galley braced, girdled, and epoxied, and probably bushed, because he runs a Buick 455 bored to 538

I have some pics of the motor with my spiffy new TA aluminum Stage 1 heads that I'll post later on. At least you'll get to see it. I might even get to start it up some day
