We just completed a bunch of new mods, ported and polished heads 30# injectors 58MM throttle body 505/530 Isky cam trans rebuild on turbo 350 mad z28 cpu tune. after about 6 weeks of working on the z we fired it up and it started right up no oil leaks wow! Then on to the road it sounded great, It used to start losing power at about 5800 rpm but now it pulls right past 6500, the only problem was off the line it made a terrible squeal and it wasn't coming from the tires, LOL, It turned out to be the stall converter. The trans is back on the floor. I had a 4000 stall converter in it and it ran pretty strong at the track, but on the road it would tach 3500 at 50 mph. This car is not transportation but I live 30 miles from my shop where I keep it and would like to bring it home once in a while. I have been researching converters and now I am really undecided on stall speed to go with, I trailer the car to both the 1/4 and 1/8 tracks in my area. The cam specs say 2400 to 6400 I know you guys have lots of bad ass Z's out there and have resolved this problem. I like everyone else have a limited budget but want to get riding. ******* Racing has converters for $250 Help! Thanks, Skip
