Make sure you check the chain to block clearance. A couple of years ago, I picked up a fresh rebuilt 350, put a few miles on it, dyno'd it, and pulled it for another project. Upon minor disassembly (replace some gaskets, strip & paint the engine), I found that the previous owner (who had never gotten a chance to run the engine) hadn't checked his clearances before installing the double roller timing chain. The dyno numbers were pretty low, and I'm going to blame it on this.
The block hadn't previously been clearanced, but the timing chain had fixed that. I pulled the gear off, and clearanced the block, and am now more anxious than ever to get this thing back in a car again...
thanks for reading, and does anyone have a good alternative to powdercoat for an oil pan? I wanted a coating that would be durable, and most of all- resist rust.. The raw steel oil pan is all that is keeping me from installing the engine...... (and my powdercoater is out of town for two weeks)
