Running 3.73. Thinking of going 4.10 but can't find an axle with them right now. I may just settle with an axle with3.73 and then switch out at a later date! WMI is on my list of things to do as well it would really push it over the top with the CAC! I didn't take any measurements before...
Ha, Thx bowtie! Fellowtraveler in the pics posted you said that an 18 was stamped but I can't see it. Can you point it out I can't find anything on mine. Thx!
Just did the same swap on my 94 Burb ! Funny I said the same thing about the sound. Most Def sounds like a big block, and your results sound exactly like mine. Only difference are my temps are lower with the CAC. You will Def love having it! Today I was cruising at 60 and egt's were 360...
