Hello, I am new to all this so please bear with me. I have a 73 Monte carlo that I bought that has a 350 in it and it has a big block vin# so I bought a 454 motor for it but then had an after thought that might be costing me, will this 1991 gen5 454 big block accually bolt up under the hood. I was going to just pull the 350 and give it a go, but being a disabled 55 year old man makes this way a very time consuming way, so I thought I would ask some of you that might know these cars a bit better than I. does anyone have any ideas on this that might help me?

 

Yes a fuel injected 454 will bolt up directly under the hood. A few thing would be needed as a electric fuel pump and depending on what induction (carb,fuel) you would need a different intake manifold to run a carb. Other than that I don't recall anything else that would be a big issue. Good luck
