351c 1973
just found a 351c 1973 to be rebuilt. what can be done to the engine to get more hp/tq than stock 168hp? is it worth it or not ? just want to rebuilt and sell it back to have money to finish the 400 project.

Nope!
Save your money for the 400. In my opinion it's very tough to make money building an engine.
A - build a high HP "race" engine, complete with a dyno sheet for a small profit
B - build a common "generic" engine that many people may want for a very small profit (if you're lucky!)
Unless your name is Jon Kasse or you own the machine shop - walk away.

good engine!
first question is what are you going to do with it and application! I personally like the cleveland and will build another. 400 ford great engine but aftermarket con rods not available. have to basically do a 434 from tim meyer for bullet proof btm end. cleveland lots of part for btm end bulletproof. not hard to make power with a cleveland and con rods pretty stout and some arp bolts. 7000rpm not hard to do with stock rods prepped up. good luck and chat later.

. Some KB flat top or mini-domed hypereutectic cast pistons plus a mild performance cam/lifters/springs (214/214 - 234/244 duration range @ .050" lift) should get the 351C right up into the 350 - 450 grossHP range easily (163 is netHP) of a muscle car engine... remove the air injection bosses blocking the exhaust ports if it has those... add a 4bbl. carb./intake and headers, or let your purchaser do that part... beware of general 'rebuilder' pistons, many have an undesirable lower compression height...
. Only need to convert your 400 into a 434 if looking for over 450 HP or so from it... otherwise, follow same formula as 351C above (using TMI/modified KB 351C pistons)...
