Well, I just finished with my 93's head/intake swap. Aside from a custom catted 2 1/2 h-pipe/flows and 4.10s, the car was bone stock. Still had stock timing.
Today, I finished installing GT40X heads (64cc), TFS Street Heat intake, and 1.72 RRs.
The car started up beautifully--took about 5 cranks for the fuel to re-fill the lines, and then *boom* it fires right up. I was impressed with the new sound; it was deeper, throatier, and just ballsier. I let the engine idle for about 5 minutes, until it hit operating temp, then I shut it off and changed the oil.
Took her out for a spin, and she felt exactly like she felt before the swap. In other words: SLOW. It's a 93 GT Vert auto, so it's the biggiest of the bunch. One problem I know of is that we haven't timed it yet, because my buddy forgot his timing light. So, the timing could have been WAAAAY off. We did hand-time the motor twice, each time with a noticable change in power. We figure that we may be close to stock timing, but he's coming later this week with his gun so check it out for sure.
However, if it isn't the timing, I'm screwed because I've spent abuot $2500 on the car, and it feels nothing like my 93 5-sp with stock heads drove. I'm really worried that aod verts just suck without major power adders. I'm even more worried that I just shat out $2500 for nothing.
Are vert aods really this slow, or is my timing just out of wack?
