Motor is pretty good ,make good power 3500 >
I had to keep the CCC carb and smog equipment being in California . That has proven to be a headache as the low vacuum the 290 hp makes . I get 16 Hg when it's rated at 12Hg per GM . so Computer is trying to adjust for the low Vacuum .
I am currently looking into the MSD Atomic EFI , as it is smog legal and would eliminate the factory ECU .
but still researching that .
Hows your 350/290 ? did you keep the factory Carb etc ?
