318 Rebuild suggestions?

Add up all your parts and machining costs then add another 25-50% and compare it. Unless you only get the most basic of overhauls (reusing pistons) a warranted long block will be a better deal in most cases. If we're wrong, I'll be pleasantly surprised and overjoyed for you and wholeheartedly recommend you rebuild it for the experience.

But by saying the only way you'd consider a new engine is if you had the money and if its cheaper tells me you've pretty much already made up your mind and until you see the costs for yourself, anything you read on this forum is non-value added.

Either way, have fun
