I dont want to go as far as installing a new cam but it looks like a have a small oil leak developing at the rear of the intake manifold. I was thinking about pulling the intake and just replacing the gaskets then I got thinking well these heads have 100K miles on them also. Truck has always run great never really started smoking at startup till recently. I've been pondering having the heads rebuilt (stock or buying new ones, dont want to mess with the vortec stuff yet). Then tossing on an aftermarket TBI intake and upgrading the ignition to something with a rev limiter. -So, who makes the aftermarket intakes and what ones flow best? -anyone with 6" of lift running a TES ypipe? Problems with clearence on the crossover section? -is MSD about the way to go for a good, reasonable priced, ignition upgrade? -IF, I did end up going to a vortec head, what aftermarket vortec/TBI intake manifolds are on the market right now? Remember I want to stay with the stock cam for now... Most likely I will run this motor for another year or two then toss it in the project truck after I build a stout 383 TPI motor for this truck. I'm wanting to start collecting parts for this to be another (late) winter porject... (along with my frame swap on the project truck and maybe finding a clean 2wd to start building into a drag racer /forums/images/graemlins/whistling.gif..... /forums/images/graemlins/thinking.gif maybe I should find a job first?).
