i am building a 400sbc. i am going to use 5.7 rods. the rods i am using still have the old pistons on them. the pin holding the pistons on, is pressed into the rod. how do i get them out? thanks
First this is not a sales pitch, but....take them to your machine shop. Getting the old pistons off is no big deal unless you are trying to save the pistons, but installing the new ones really should be done with a rod heater. This is a device that has two heating coils that heat the small end of the rod up to a specific temperature so that it expands and the new pin just slides in. Most shops have a set fee for removing the old pistons and then installing your new ones.
Hope this helps,
