318 Port match heads to Performer RPM Intake
69 318 with LD4B aluminum 318 intake and 302 heads.
1991 318 with 302 heads and TBI cast iron intake converted to 4 bbl application. 91 stock intake is more of a factory high rise with a bigger Plenum.
For some of these basic drivers and those that want a 4 bbl can do the 2 to 4 conversion. Not for everyone but they actually work quite well for a driver.
It's hard coming up with small port intakes for the 318s, so this is one alternative that I like that gets the 318 intake ports matching to the 318 heads.
91 stock TBI intake on left, more of a high rise and bigger plenum.
74 stock intake on the right
Both work as an alternative.
