    Engine rebuild or replace

    Hey guys! I have a older savage x 4.1 that I swapped the motor to an os 30 a few years back. I’m starting to notice the age and not sure if I should rebuild my 30 or look into another motor. Since the os 30 is discontinued is it worth staying with that motor? On the other hand I’ve had it about...

    My stock Savage 21 engine gave out and I found a cheap brand new Picco .28 for sale but I was wondering if it’d be a good fit for my car. It has an aluminum chassis and 3-speed differential.

    Picco P3.28 pipe questions

    Hey guys, I put my picco .28 back on my savage and was wondering what is a good pipe for this motor. It’s been a long time and things have totally changed these days.
