well i posted this over in the 2nd gen v8 tech but got no answers so i thought i'd try my luck over here... i've got a 76 camaro that i plan to put a 454 into but i'm not quite sure what i need to do for motor mounts and i was hoping that some of you guys could help me out... the car has a 350 in it right now but i'm sure i'll still have to swap mounts... is there a car i can pull them out of that will work for me or what do i need to do?

Don't know for sure on 2nd gen cars but I'd wager it's the same as 1st gen.
All I had to do besides headers on my '69 to bolt in a 427 was change the mounts for the block to big block parts,the frame parts stayed as they were,very easy.
You can likely use 1st gen BB motor mounts but I don't know for sure.
The biggest pita was the heater had to be changed out to a bigblock heater because the hose connections were behind the head after the big engine went in,not sure if that's an issue on a '76 or not.
You will need a different flexplate or flywheel,454's are externally balanced so you can't use your old pieces from the smallblock motor.
You could with a 396-427 though,it's all the same as the small block stuff.
Everything else should bolt up fine but you'll want a bigger radiator to handle the heat from that big motor.
