Well you have a nice high hoodline on that truck, I would suggest going for the rpm performer manifold with the 600crm vac sec holley for the street and for strip work to go for a 750 cfm double pumper holley to punch it off the line and to let the engine breath at hiher revs 3/4 of the way down the strip. So all you have to do is change carbs open up the exhaust, get high premium gas and advance your timing to wring a bit more HP out of it and you should have the goods.
