Hi there, I have a 69 C10 that originally came with a 283, I noticed on the frame that there are additional hole to move the motor mounts either forward or back. I will be putting a 406ci SBC in the truck and I wanted to move the engine forward a bit so that the rear of the motor is more accessible. I was just not sure wether doing this would affect the weight balance of the truck to much or if there are any modifications that would have to be done to accompany moving the motor forward. Thanks in advance.
