Some may remember that awhile ago I cracked my Cobra lower. I replaced it with a TFS Street Heat w/TFS elbow adapter. Before the Cobra cracked, the motor was running strong and though I had some converter issues in 2nd and 3rd, first gear was a downright beast and I was able to annihilate my 275/40 drag radials easily.
Well, I got the new manifold installed. Fired it up, took it for a spin, and the car was WAY, WAY, WAY down on power...I mean, pathetic. Absolutely mother****ing pathetic.
Up to 2000 RPM with LIGHT driving it felt normal. The car idled well. But anytime I dipped into the throttle it just...choked. It revved very slowly and just felt like there was an anchor tied to the back of it.
So after some research, I figured that since the front fuel tube (between the two rails) was pressed between the distributor and lower intake fairly snugly, it may have been pinching and causing the driver's side bank to starve. I pulled the upper and ground more material off of the lower to accomodate the fuel tube. It has room now.
I then reinstalled the upper. Same symptoms as before.
Timing is set at 10*. Fuel pressure is set at 40PSI. All sensors are connected. No check engine light. No noticeable vacuum leaks. Idle is rock solid. No weird sounds. Just NO POWER at all- I'm confident that both my wife's ZX2 and my V6 Firebird could absolutely walk my 5.0 right now, and that really sucks.
I know it's a long shot (and this post is more of a rant then anything) but if anyone has a suggestion I'd love to hear it, before I have this POS towed somewhere.
