Thank you George.
I'm shooting for great driver @ 375-400 hp with 30 over and flat tops, slight bump in the cam (unsure about roller cam) and steel roller rockers ( something I can fit under the steel covers). Big bore headers and possibly mod/gut my extra mufflers (mothball my factory exhaust system) Still in the research process but, I like the look of the stock intake and bonus my stockish air cleaner should fit nicely.
Previously bored 30 over and re-cammed with around 10k on it, sadly. I think he struggled ever since to get back low end power so he recammed it a second time after experimenting for several years.
A good friend of mine said a few years back he took a Offenhauser intake off that had a terrible port match, that's when the 69 intake was installed. Not sure it was 100% even then.
A waste of years of driving enjoyment, .030 of cylinder wall and $$$$. Probably all because of a 1/4 mile mindset. 2 major teardowns in 10k miles , (only 20k now) That had to stink bad, Hoping to avoid all that . (I have a low tolerance for comebacks and headaches , especially on my own car)
Thanks for the reply and advise. Have a great Easter
