wondering what you guys with a 454 in a 81-87 c/10 might be using for headers...what brand fits best..

also, did you have to change your front coil springs to compensate for the weight of the big block?

will the bell housing from a th350 that was bolted up to a 327 still fit the 454?

did you HAVE to change your fan shroud...seen alot of big blocks in el camino's that used the small block fan and shroud?

would i need a different fan clutch...

i all ready have my brackets! just these last few items are in question....goin to the parts yard this weekend!
