i have a 74 taylor with an olds 455 and a spun rod bearing. i want to swap over to a 454 i have. my olds has a mount on each side of the front of the block. i can't tell where it connects in the rear. i have front and rear plates for the 454, logs and the 454's berkeley connection. do i need to use the front plate? what all is involved in this conversion?
thanks
