i was preping the engine bay in my 63 chevrolet getting ready to put in the 292 very soon. this truck had a v8 when i got it but i think it was originally a 6 truck. i have been told you can move the passenger side one foward to accept the 292. i was getting ready to do this and there isn't a lower hole for it in the right location. there is one on the frame but not on the bottom. do you just have to drill this? i assumed it would be there. the only one is not in the right place. am i just missing something???
