66 289 block with:
gt40p heads
Performer RPM cam/lifters
4105 600cfm carb
Performer 289 intake manifold
Its backed with a 5 speed and 4.11's
I did the head and cam change myself, set the timing to 16* BTDC and all was fine.
I didn't want to do the exhaust just yet, so I just bolted up the stock manifolds that have a cutout after the Y pipe going into the 40 year old single exhaust.
It feels like there should be more, the car runs great... but it feels like there is more power to be made.
Do headers really make a huge difference, say... over the stock manifolds? I know its a stupid question and the answer is YES, but on a modified engine are they really needed to utilize the full potential of all the parts?
