Yes that cam is underutilizing the money you have sunk into those heads.

I see this all too often with the builds that folks post about in this street section.

That .470” lift is just starting to get into the lift range where the added flow capacity of aftermarket heads ( even just out of the box) start to shine.

As far as my thinking goes goes any after market head should be run with a minimum of .525” lift .

Your .470” lift is sacrificing ( due to low port air speed) a lot of added torque you could be having the motor producing, and probably a minimum of an added 25 hp.

The added port air speed would make a day and night difference in throttle response feel.

In short your heads are like a fire hose with a glass of water passing thru it, there’s only minimal port energy taking place..

As I look back thru this crazy 6 year long string of post, of which at least 50% of them should have been posted up in the body work section I see where in post 158 where you fell into the trap of having your heads ported and opening your wallet even wider for that port energy reducing mod in terms of the cam you are now running.

So to recap,
You paid for more air flow then you are now using and not using that air flow capacity is costing you power .

$2500 for basically a headliner is ridiculous. Or are the rear panels you just got covers for?

Those rear panels assembled repop are like $175 for a pair, and are bolt it.

The sail panels are just cardboard with material glued to them. I would imagine those are fairly inexpensive too.

You need to shop that better, bow headliner installs should be under $1000, and that's on the high end.

Have a pic of the cleaned up wiring?

That’s kinda what I figured. Paul Carter spec’d me a cam on my ill fated first build that was awesome but when the engine grenaded I just didn’t have the money to do a roller setup at that time. Cars still plenty fast right now and I can’t really abuse it cause of the 3rd gear issue. Oh well I kept the voodoo cam because only one lobe needs to be reground. I’ll do it one day.
