Hey guys , does anyone kno anything about the target master 350? i have one in my 81 3/4 ton... it was installed in the early 90's... it has about 150,000+ miles on it and still runs pretty good..but the truck isint doing very good( very rusty etc), anyway i want to use the block for a upcoming project... a high revving, solid roller, stroker engine with moderately high compression.....anyway is this block gonna be ok or should i scrap the whole idea? i kno its a 4 bolt main which is good and i have heard that they are high nickle etc etc but then i also hear they are crack prone and bad/ruff castings....any help to set this strait would be great, thanks very much
