You might think about going to a taller tire if possible. That's a pretty small gear change. A 2 inch larger roll out would accomplish the same result. I assume you are going to a 350 combo now. I ran my 350 with a 6.17 and a 101 roll out Radial tire with good results. I put a 5.86 gear in the car now. I had less engine breakage with the 6.17. I guess that put less strain on parts even though the trap RPM was a bit higher.
