Hey everyone, new here..... I have an 87 Indy sport 340 I picked up for next to nothing..... ran great till it didn’t and I found about an inch and half of my position ring jammed into my spark plug. Wanting to know if a swap for another fan cooled engine is possible. I don’t want to go into any major fabrications (other than maybe drilling new holes in mounting plate if required) I know it’s never going to be a rocket but any extra power is that much more fun in such a little sled. Am I better off working a 400 or 488 if possible in there or is my only option to bore it out and see what I can get? I found the part number for the mounting plate but was having a hard time finding anything to match it, so I figured I’ll come to the pro’s. Thanks in advance!
