i have a 1990 c-1500 and im looking for the best shift kit. any one have one on their truck thats any good?

I put one on my 1990 1500 700R4 out of summit I think it was a B&W. One Other thing I did was install a Boost Valve I got on E- Bay made a big differance.

Get A Servo For A Corvette 700r4
You Will Feel The Shift Get Much Harder

I have an 89 C1500 with a 4 speed auto with O/D. It wont let me shift into first myself, but 2,D, and OD work. Would a shift kit help me any? BTW it takes a good 2 seconds after shifting manually into a higher gear for it to kick in. Like 2 to D.

dont the corvette servo help with the 1 2 shift? so if so i think you can get one off of ebay for under 20 bucks and id almost say itd help you for a short time tile your sunshell and planetry and etc blow ups :(
