possible to change rod bolts with the motor still in the car?
might be upgrading to ARP's for peace of mind since i will be revving the stock bottom to about 6800 quite a bit this season

 

If it was possible, I don't think it would be a good way to do it. Usually, you want a shop to remove and reinstall rod bolts with a press. They can be pretty tight.

 

Shoebox is right. Never heard of it, and thinking about someone actually doing it makes me cringe.

I had the ARP's put in my rods and they had to press the pin out, then get the old ones out, put the new ones in, torque them down and resize the rod cap.

 

Yeah, you'll definately want to have the rods resized after you get new bolts installed. I think it cost me $125 to have new bolts installed and rods resized when I did my motor. It seemed like a fair price, especially after I had to spend ~$300 to have my rotating assembly balanced with the Speed-Pro forged pistons. Those suckers are heavy! It took two large pieces of Mallory metal to balance it, but it's smooth as silk.
