 Mike, I didn't test with/without the electric pump.  It's probably not worth much, 5-10 hp, but the benefit is that he can turn the pump on without the engine running, which is handy to cool the engine down between passes.  This is strictly a drag race engine.
 A distributor with a crank trigger is about as rugged and dependable as you can get.  When you point a timing light at the balancer with the engine running, it looks as though the engine is not running at all.
 
 Dog, I wouldn't expect much more with the CHI heads over a good set of TFS or AFR heads.  Keep in mind that going to a Cleveland head necessitates a header swap and probably an accessory bracket swap....in addition to new pistons, etc.
