honestly you could start with the vortec block if its any good, the rotatig assembly is slightly stronger, the roller cam debate is your choice, you have more cheaper flat tappet cams available but a good selection of roller cams as well.
free vortecs id say send me a pair, have them magnafluxd at the least to check for cracks, as stated no the intake will not work youll need a carb to vortec manifold, jegs has one for 127 bucks or something around there, i would recommend that. its your cheapest unit and with a bit of polishing or even iwhtout it stands up neck to neck if not surpassing the edelbrock manifold that youll pay wuite a bit more for. your bore size just affects your overall cubic inches in a stock application theres no real differemce except that of caution, your a machinist so youll know to check your bores for out of round and so on, i personally dont like going over 40 over in any 350 block. if it were me and needs a rebore id look at one of the junkyard blocks. i bumped my compression to 9.7 when i redid my motor(a few times) i wouldnt say to have your man goal to bump your compression, but make sure everything you do fits together nicely, such as having a bigger cam, retain proper valve train geometry, make sure your intake and exhast can flow enough, make sure your fueling is proper that your trans can hold up to the mods youve done. i always say planning is more than key and take your time. start with a block that isnt the one in your truck if its still driveable and if you need to drive it. that way you have time to research, do it right and save some money in the process.
