Best aftermarket intakes for an early 273?
his 273 is stock,, and low compression and a 2 barrell cam,, a single plane intake is for high RPM,, a dual plane is what you want on a street driven car,,even more so with low compression and stock cam,,rear gears,, stock to mild,, dual plane works on the street off idle,,,a single plane comes in around 2500 rpm and up,,,street driving you want a intake and cam that comes it at or just off idle,,,
single plane will make more power on the dyno providing the motor is built properly for high RPM,,
as for the 273 bolts,, they may be smaller in dia,, but the angle is also dfferent from the 64/65 to 66 and newer,,,that why the holes on those intake are hogged out,,
as for the kick down,,if you can cut the 2 barell linkage,,,add a piece and re weld,,or attach it together,,,,you can modify the 2 barrell bell crank,, that would be the cheapest,,,but the cable kit comes with all the brackets,,and is a simple install,,,,LOKAR,,, BUCHLION OR JUNK YARD,,,,
