There is a gap between the hood and the front bumper is the source for the engine air. There is a mod I'm doing later that will make a hole in the top of the radiator enclosure to basically provide ram air to the intake. This engine breaths through ducting in the hood and if I go TPI then that will go away when I have to replace the hood or use a filter stuck beside the engine.
The only other large body seam is the top of the windshield and the terga top. It has a bunch of air leaks as it is and I may as well seal it off for the winter.
Short term mods/repairs that may help are:
Replacing the HEI distributer control module (Accel) to deliver more consistent spark to the plugs.
K&N filter
Under drive pulleys
New weather striping
Replace the banged up chin spoiler
LED lights for less pull on the alternator in the dark
The spare tire has been removed (it was full of mud and water so now I have a tire plug kit and 12V pump) Lost about 50 lbs. The AIR pump/plumbing was already removed, not me. That's why I installed the heated O2 sensor for now till I get exhaust back up to par.
And keep my foot out of the gas.
