DRR Trophy
| No more issues with roller vs Babbitt bearings. Use a raised cam block or 2.100 rod pin to help with cam to rod clearance.

| Brodix aluminum block here, 55mm needle bearings...no issues whatsoever. I actually asked to have the babbit bearings instead, block showed up set up for rollers...oh well. cam does go in easy and turns really easy....if that even matters Mark Goulette Owner/Driver of the Livin' The Dream Racing dragster www.livinthedreamracing.com"Speed kills but it's better than going slow!"

| Most of the frictional losses in an engine are from the piston rings. Honestly I don't think you'd see any difference with one over the other. I went with them because that's how my block came...

None that I'm aware of. Other than lifter bores being oversized nothing has changed in my block except there are no oil supply holes to the cam bearings Mark Goulette Owner/Driver of the Livin' The Dream Racing dragster www.livinthedreamracing.com"Speed kills but it's better than going slow!"
