A Preview Of Upgrades For The 2006 Pump Gas DragsFor the upcoming Pump Gas Drags, the engine will be running some new top-end components. A Hogan sheetmetal intake will replace the Victor, and a set of AllPontiac.com Tiger heads will replace the wide-port E-heads. Under the valve covers, 1.65:1 ratio rockers will be swapped in for the 1.60s.
"The struggle with the engine has been getting more air into it," said Robin. "We want to improve flow with the Tiger heads and the chamber design is improved, which should help on pump gas. The Hogan intake will fit these heads much more easily than our current Victor and will flow better. We're looking to pickup 60 cfm on the intake side and have a 66 percent exhaust to intake flow, which is a significant improvement on the exhaust side over the E-heads."
Lastly, a set of 4.00-inch collectors has been added to the headers, and the cage will be upgraded as required for the e.t. that Robin is shooting for--very low 8s on pump gas.
