Some of you may have heard of Preston Smith and his 9 second IROC – here is an article on how he pushed his car into the 9’s over the years with all the combinations he tried. The 9 second combo consisted of a 305 with forged internals, TFS heads, roller cam, ported factory intake. Vortech V-1 pushing 25lbs of boost through a home made air to water intercooler: 9.95 at 135mph! Enjoy.
