It sounds just like my car and I have the stock cam.

Ya I'm pretty sure I don't have a camshaft. But I guess that will be my next step in the future.

Re: What should I do next?

Put the torque converter in today. Yank ss3600. Feels pretty good. Not as loose as I thought it would be so that's a good thing. Only thing is it feels like my shift kit is gone because it shifts to second real smooth. I guess that's just because of the converter. I'm sure I'll feel it again when i go WOT gotta break it in 150 miles.

I don't feal a big difference with the torque converter at all. I feel like I got the negatives more than the positive. I mean I can brake hold it more and it will shred the tires but it's not like I thought it would be. Yank ss3600

Ya I'll see what it does for me at the dragstrip. I'm sure my butt meter can't feel a half second difference.

Re: What should I do next?

I just changed the spark plugs, there autolite. Im thinking about changing the cat, maybe buying a highflow or removing it completely but I dont want to throw a code. I think I changed my coil already. But I did not change the coil wire because It had a nice blue 8mm wire on it while I used stock wires on my sparkplugs.

I want to delete the cat, I dont care about passing emmisions, law and whatever. I just dont want my computer to throw a code.

Re: What should I do next?

Your 94 does not set a code if you remove the catalytic converter. There is no after-cat O2 sensor in an OBD-I car. Unless your cat if plugged, removing it isn't going to accomplish much in the way of power gains.

Any way to tell if it's plugged by looking inside of it? I plan to take it off.

Re: What should I do next?

You check for a plugged cat by measuring the pressure in the exhaust system. Any decent exhaust shop should be able to do that for you. But if you are taking it off, what difference does it make?

Just out of curiosity that's all.

I'm about to buy some stock heads today to use them for porting.

Re: What should I do next?

Which castings are they - 643 or 561?

The photos are gone, but read this:
