4.2 or 5.0 Lever

Any advantage one over the other in a 904 full race under 350HP? Thanks

Not at that power level.

T think a 3.8 would work just fine.

Most trans guys will tell you to avoid the 5.0 anymore and use the 4.7. I use the 4.7 in everything I build.

I use the 4.2 whenever possible.

Go with the 4.2

haven't ran the trans yet, but I went with a 4.2 based off the recommendations from a lot of builders I talked with and guys on here as well.

I run what the valve body guy says to run, or what he prescribe.
Cheat vb still recomend , the 5.0 , while other makers of trans brake do recomend the 4.2!

I run a cheeta TB vb in my cuda with a 5.0 and 277 first gear. Was doing that weighing in at 3800 lbs. 129/131 60 fts a hundred passes or more on it and when tore down for inspection over the winters, parts are still good. My trans was set up for me this way, I went by what was built for me. I can't recomend what's better to use, only a testimony on what I have been using is all.
