Default 69 Camaro SB to BB conversion questions

ok so my boss has 2 69 Camaro's, he just bought this crate 454 off his buddy and wants me to put it in one of them. I believe it has a basic 350 sb with a 4 speed in it now. I'm not sure if hes sticking with the 4 speed or not at the moment. My question is... Is there any thing that will need to be changed or moved on the firewall, accessories etc..?

i have never worked with big blocks and ive been tryin to get him to put a LS motor in it instead.

Nope bolts in the same place as the small block but it will use different acc. brackets for alt. & PS.

No there OK where they are. I had a 68 Camaro and went from SB to BB and the only thing u want to change is the front springs because of the weight difference.

Yea there is another difference in that the engine stand offs are different for the big block. go look them up at calssic industries or sumthin. I Might have them from my camaro still Im not sure. If you dont use the right eng stands ull have header issues.
And yea your right if he had half a brain hed sell the big block for what its worth (nothing) and put in an LSX 427. I built a 12k 496 BBC and sold it before I ever installed it =)
