I have an 84 Chevy Scottsdale pick up truck that ive been rebuilding. It has a 3 speed manual trans in it. This truck is NOT meant for the highway. If i get over 55mph im turning some serious rpm's. What can i do to change that? Is it as simple as swapping out the ring and pinion? Thanks for any help

 

how is this third gen related??

 

Well it just depends on what ya got now. Ive got a 76 short box, 3 speed manual trans and 373's in it. Highway isnt to bad only 3k at 75 mph. Your trans should have a 1:00 final ratio so they only option your would have is an overdrive trans or a different rear end ratio. Most trucks of the smog eara were 3.08 rear axle trucks so if you wanted to step down you can usually pickup a whole axle for $200 no need to mess with a gear swap but I suggest seeing what you have in the truck now before you make any decision.

 

ok thanks ssc, i'll do that....sorry to waste your time joe, i joined here to get advice on my truck project, not to get smartass answers.

 

Since TGO is dedicated to 82-92 F-bodies, you might consider another site, one which would be more helpful to truck owners.
