The Jet and SLP MAF are BAD BAD things, and if you don't hit your goal they are why.

That's an awfully expensive setup for not much gain. Stock manifolds are terrible.

The difference is noticible and with a heads/cam car, the difference would be substantial.

Yes you can install LT's with the engine in the car. Both times I did mine I did not have to lift the motor up off the mounts any. However, if you have access to an engine lift, it is easier to unbolt the engine mounts and lift it up a couple inches. The best time to install the LT's would be when you do the heads/cam swap IMO.

Baseline numbers are 268/305 with SLP and no Airfoil

Borrowed my buddies MAF and AIRFOIL and 273/308

so either that AIRFOIL works or 96capricemgr was right about the SLP

Damn RamAir95TA and I are good! lol

Considering the airfoil is good for probaly 2-3rwhp, he is right about the stock MAF being better. The stock MAF is one thing I do not recommending changing out for aftermarket piece.
