Hoping so. I know that on a 350 with AFR heads and the LT4 "hot cam" the stealth ram intake picked up nearly 60 horsepower at the wheels over the stock TPI manifold.

My setup should flow similar to the AFR 190 heads (maybe a bit less), but I have also read a few articles where people picked up 20+ hp moving to COP setups. So conservatively I think the sequential fuel and COP spark should make up for the differences perhaps lost by AFR's heads being superior to my trickflow heads, meaning I'd anticipate around 340 RWHP, meaning it should be around 374-408 HP depending on drivetrain losses between 10-20%. If I could get a roller cam in there I'd expect another 15-20hp and perhaps another mpg all else being equal.

Plus I'm just hoping I'm a better tuner now than I was in highschool . Having a wideband sensor, along with Megasquirt's autotuning capabilities should help me in the MPG department I hope. And fixing the converter lockup should help as well.

My biggest concern really, after 7 years of not having this car in my possession, is that the engine and tranny are still solid. Everything looks okay, but I won't really know until I get it moving.
