SBC double roller timing chain clearance

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)

Just clean the pan good and then spray it with Brake parts cleaner to make sure there's no oil. Use engine spray paint, what ever color you want. DupliColor etc.

I have a good amount of POR-15 Engine Enamel leftover from painting the engine, I was thinking of using that, but didn't want to learn the hard way that it might not be enough (not wanting to have to remove the engine just to replace the pan, and the raw steel pan is brand new, figured I'd do it right and never worry about it again..)
