I'm looking at possibly changing out my stock cast intake for the 69 RAIV aluminum intake, basically for some perf improvement and mainly to remove the crossover completely due to ethanol's low evap temp. I don't see any block off plates made so I can make those. There's just seems to be no real details about these except they fit most Pontiac V8's. I have a 68 WZ block in a 67. My questions are--
what are the differences between the 69-72 factory aluminum intakes??
what is the RPM range of these manifolds?? can't find that anywhere
has anyone run these? your thoughts?
seen some posts that the copies being produced are not good quality, any feedback?
are they higher than stock and affect hood clearance?, I am running a RAI intake setup
