Well nogo69
If you want to step up the performance then it is time to Think of what you really want & Want to do.
1) first off a cam change is in need a Rv style Or tow cam. But i would say step up to something a little bigger.(stay with a hdy cam) But don't get to wild here because you will surely Need to step up you stall convertor for sure.
2) up-Grade to a HEI.
3)Intake system. Stick with a Offey intake Good Low to Mid range Power & torque.
4)dual exhaust. Either headers Or Tom Langdons dual cast exhaust.
5) Think about the Rear Gears.( 3.32,3.55)
6) Your L6 will like a extra Gear so think about a Tranny up-grade ( turbo 350 OR? something like the 700r OD) a OD is Nice it will also help In your double duty ( daily driver/ weekend racer)
with the lower first gear, Plus the OD for those wanted MPGs
7) Last but not Least think about getting some head work done.At the Very Least clean the ports up and a good 3 angle valve job.
One of the Biggest keys to making our L6 make more power is The HEAD,If the motor can't breath
good Your getting no where. A good Valve Job and Mild port work(bare bones clean-up the Ruff
casting)will run you around a grand(1000)
Hope this helps for starters.
God doesn't like ugly.
