i've got an L67 in bits ready for the come stroker to go in, and have heard the same about speed pro lifters, so i am also keen to get a different brand lifter put in. I called my engine builder to see what he could find out... apparently the speed pro lifters are only rated to 6000rpm, and something along the lines of a GM product being available for the v6, a "performance" lifter similar to LS1 lifters that are rated to 8000rpm. I only got sketchy details thus far, but when i find out more i'll post up here.
Anyone else got any additional info?
Cheers
i've also heard of using LS1 lifters in the V6. i've defintily heard of a few lifter failures with the items supplied by COME. i wouldn't touch em personally (the lifters that is)
