With the possibility of having a hurt motor (wiped cam, bent valves, or other issue) its time to think about starting a hot SBB build. Instead of taking the car out of commision I plan on building a replacement engine that I can swap over when done so I can keep the car in running condition and take my time for the build. I'm looking to build a 450hp+ motor, trying to center it around the upcoming TA heads and single plane intake as much as possible given the limited info available at this time. Of course I can't do to much without knowing more about the upcoming heads. And I have to plan for the unfortunate possibility of a delay in head manufacturing and using iron heads instead. I'm looking at picking up a running 72 350 from Bruno. So at this point I'll be looking at breaking it down, doing a little bit of inspection and getting some measurements before machine work. I'd like to stick to a shortblock budget of $2000. It's going to be a roller motor and N/A although I'd like to build it in such a way that it could be used in a mild boost application ( <6psi) I would like to be one of the first to build an engine for the upcoming TA parts so I don't want to sacrifice performance for cost, I see this getting expensive. After tear down I'll be taking the block to the machine shop for cleanup and testing to make sure its a good motor. As long as it can take a .030 overbore I'm not too worried about having a perfect "unshifted" block. I suppose the best way to go would be 73+ rods but what benefit would there be in using aftermarket rods in this application and what is availble? I know it would most likely be custom and this will be a sub 700hp motor so I don't need anything too crazy. Not looking to shift higher than 6500rpm. As for pistons I know there are the Auto-tec forged pistons, which seems like the best choice but if I can order through a dealer that supports this community I would like to go that route if anyone has some suggestions who to order from. What should be done as far as block modifications at the machine shop besides clean up? I know this is broad and some stuff I know already but I would like to have a list started to get a better idea of costs. Cam will wait until there is more info on the heads but I guess after cleanup and testing I will have to make a choice on deck height and pistons in order to keep the CR within range depeding on what head size TA comes up with. Or will I have to wait in order to get the best combination? Sorry this is so broad, it would just be nice to get some brainstorming done on here.
