I am a huge fan of supercharged hot rods. I have 6 cars with blowers. My latest build is the only one with a th350 trans that has a standard valve body in it. Most of my cars are stick, and the few with automatic transmission's are manual valve body conversions. My problem is that my car seems to pull too much vacuum and shifts at unusually low rpms. I have installed the little ball valve blow off with restrictor. I am running a 475 horse small block chevy with a 3000 rpm stall and my cam is 500 lift hydraulic roller blower grind.what am I doing wrong?
On the transmission change the springs in the governor (back left near the tail shaft there is a domed cover) get a spring kit or go over to your local transmission shop and see if they have any springs on hand. It only takes about 10 minutes to change out I will try to dig out what springs I used tomorrow (i think a green and a white).
Thanks. I bought this trans done, and it came with a few different springs. I had no idea what they were for.
