after also asking in forum , see is there a better shifter , the best appears to be the PPP shifter then a close choice between B&M proratchet and Cheetah SCS (Turbo action) and so on down the line
PPP is not always easy to get ahold of.... but on two occasions they have called me back at least after 2-3 days. I was at the right place at the right time when this one came up for sale, and it was ready to go with my clean N transbrake. Not cheap, but walk through the staging lanes and you'll see a ton of these out there. I've heard nothing but good about the product.
Are you going to shift it or is a box or some other device going to make the shift? If your going to shift it I like and use the older Fairbanks, Winters ,AKA Turbo action shifters If the box is then one like the one showed Mine, shiftnoid, is air shifted in S/P car based off of RPM out of the Biondo 400 box
in my case the shifting chore will be handled through an ACD split shift control box. It will definitely help me get the proper rpm on my 1-2 shift as the small block likes to wing up past that shift point pretty quickly. I really had no intention on going that route, but the deal came up so I jumped on it.
