Now's a good time to degree in the camshaft.

And I'd chuck that electric pump in the trash, it's probably pretty wore out from cavation anyway.
Go back to a mechanicl pump and don't worry about noise and cavation(vapor lock) because I'd bet you don't have it plumbed right or with a large enough feed line. It's a street car right? and you want the wife to go with you sometimes? right?
