Anyone try these distributors?

Need a distributor to finish the engine and power up the son's duster, and was just curious if anyone had used one of the self contained HEI ones like this?

They lost me when they called the Poly 318s a "Y Block." That just makes me crazy, they are not Y blocks and I get sick of seeing that. It is very difficult to tell them from an LA block, unless you know what you are looking for.
