Thinking about selling the 1998 4.3 vortec heads and cam from my motor.Heads have 1.940 stainless valves,exhaust are 1.500 stainless valves.Heads have been machined for a 7/16" stud and guide plates.Heads have been fully ported,picked up around 30 cfm over stock. 62 cc combustion chamber.They come with springs set up for a hyd.roller cam.
Cam is a cam I bought from Clevlite..478"/.487" lift and 210*/214* dur @ 50. hyd.roller
If you want V8 power out of a 4.3 this is the parts you need...LOL.My motor dynoed 290 hp on gas and 280 hp on pane.Motor had flat tops and 10.5:1 comp.ratio.I was running 1.6 roller rockers.
asking $1000.00 frim SOLD
