Brent,
I see your arguments regarding the 347 but will stay with the 331.
The KC cnc ported 165 AFRs are on my shelf since a month because i planned to drive my 5.0 without rework, just remove the emission parts, add new heads, cam and intake.
After the internal inspection i decided the rebuild, the decision for the 331 was made 1 month after the heads arrived...
Shipping costs to the US and back to Germany to exchange them for 185s are about 400 USD for these heads.
For the carb I will go again for the QF HR Series, for the 331 SBF the 600 cfm should be big enough for my planned rpm limit below 6000.
Can You send me a quote for a custom build/adjusted 600 cfm QF HR series inclusive shipping to Germany by mail to
uwe.mueller@jci.com?
Thanks,
Uwe
