So which UIM is preferred or boost? Those I've asked haven't noticed a difference from a ported 3400 to a 3500 UIM on N/A. Which one flows better, if either with forced induction?
So my options are gasket matched 3500 UIM with 65mm TB Or 3400 UIM ported to match 65mm TB and 3500 lower. Will be using 3400 heads/LIM until I can get some ported 3500 heads/LIM.
