Rhoads Variable Lifters. . .Auto-X/Road Racing???

[atomicjoe23]

Has anyone used Rhoads Variable lifters for Auto-X or Road Racing???

Thoughts, experiences???

I've got a '67 Firebird with a 400 that I'm doing some top end upgrades too and just read about these in the "Building Max Performance Pontiac Engines" book. . .that book is geared towards drag racing so I was wondering if they would be beneficial for Auto-X or Road racing. . .sounds like they might be.

Thanks for the help!
