Re: rod replacement?
For the price i would. A few of us are using the SPOOL brand rods with ARP bolts and they are great. I have been racing on these for almost 5 years. Rods were always the weak point in pinto's and now those rods are 35+ years old so they certainly wont have got better in their old age.
The only thing to take into consideration is the SPOOL rods are cosworth length which means they are 2.5mm longer so piston tops either need to be machined (not ideal) or forged pistons made to suit which is what we have done.
At around $350-400 a set these days they are great value.
To be clear - i have no vested interest, i am just a happy user of them.
