I put an ebay ($1,000.00) Vortech supercharger on a 360 Magnum that had been treated to a set of TTI headers, an air-gap Chinese clone intake manifold and a Hughes cam. Those are the ONLY performance pieces on the otherwise BONE STOCK engine. It makes 10 pounds of boost.

The blower took it from a 13.35/102mph to mid 11s @ about 117. Made a different car out of it...

No argument from me Bill -

This was my engine builder's twin turbo 318 -

630 FWHP running a 282 advertised duration camshaft and mild 360 cast heads - but the plumbing scares the beejeesus out of me! :prayer:
