Over this summer I purchased an svt engine with a vortech already on it from my local junck yard with only 46k. I've been doing the work on it slowly over time and just got to the point where I drove it. I know the engine won't run at 100% because I only had it at an ide for a few times since then and old gas is an issue. Theese are problems I've encountered before though since I'm always storing it on deployments. My problem is that it revs so slow. Like I'm trying to accelerate with a 1000 pound trailer out back. I can feel the difference in increased tourqe. It just seems so slow though. It even takes a real long time to rev not in gear. Theese are all not problems I had with the old n/a engine. Even running off of 4 1/2 cylenders. Any thoughts?
