I've got a 79 k5 with 4:10 gear do you guys think that's enough to run 38's to 40's??

With a small block she might work some, but with a 400 or big block will work. I have 3.73 and 40s......

With the HP robbing th400 and a high geared 205 and 40's I would run at least 4.88's

My 35's are OK with my 4.10's/241/th400, but I am moving to 4.56's for the next set of tires.
