replacing short block

[68_c10_on20s]

hey guys i know this is the wrong spot for this post but it will be seen by alot more people here so here goes,i have a 76 shortblock 350 and was wondering if i could use it in my 94 truck will i have any fitting probs in the front going to the serpintine setup,also about the 4l60e trannt bolting up?i have some late model aluminum heads on the motor now i was going to use and just keep the factory tbi setup,i also know ill have to use a block plate for the fuel pump but any other problems i should be aware of,also i dont know if it matters but the seals are diffrent and i might not be able to use my exaust manifolds since the heads are angle plug...or should i just rebuild the motor in it??????....Steve
