they do make a difference, my 52 had a 235 with the s-10 five speed and blazer rear end.. I was running a 2:73 rear ratio..

used it a lot on the hi-way.......it would go as fast as I wanted, 72 was normal on road... had it to 80 a lot but always backed off..

these trucks have to be in good shape to run like that on the open road and mine was... I miss that old truck
