That looks like it is more destined for failure than just leaving it!
Honestly, ever since the first time I tore apart a 347, I didn’t like anything about it. The wrist pin intrudes into the oil ring, the short deck limits the rod/stroke ratio which side-loads the piston and wears out the cylinder wall faster, and the block has to be notched at the bottom of the cylinders so the rod won’t hit the block. It is 10lbs or shit in a 5lb bag! A 331 gives you a little more displacement, but not enough to justify the cost of the stroker, and ultimately with the same head/cam/intake, a 302 will make the same hp, just at a higher rpm, and since the weak point of 302s isn’t the rods or the crank, or even the pistons, but the block, my philosophy is if you want power out of a 302 based motor, run a stock bottom end and spend your money on top end parts, and if you must have more cubic inches, step up to a 351 based block, then you can go up to 408” and 7-800hp on a stock block.
