wfridolfson 10 Report post Posted October 3, 2014 I recently put a built 351W in my fastback acouple months ago and all was good, drove it yesterday and when I hit it, it was as iff I had my foot on the brake for a few seconds and then it took off, when I let off it sounded as if a turbo was spooling down, and also after this when I parked and restart car its as if, starter doesn't engage the same way, the torque converter is a TCI 2400-2600 stall. had this in the car with a mildly built 302 and never had a problem in over 2 years, trans is a C4 with only mod is shift kit, thanks for any help Quote Share this post Link to post Share on other sites
MikeStang 247 Report post Posted October 3, 2014 How built are we talking about? you check the fluid with it running and warmed up? or Cold ? Or? I had my last converter built with Anti Balloon plates, but only because I was running turbos and Nitrous but my 4R70W has a stock converter in it but at 550 hp flashing to 2800 or a bit more but I have yet to get on it hard.
