My question is will the GM 454 fit the chasis of my IROC, the GM site says the oil pan will not clear, i have a friend with a 502 in his, anyone with a 454?

 

Well they're the same size externally. Just use the same oil pan that your friend used and it'll fit.

Where there's a will, there's relatives fighting....... OOOPS!!! :sillylol: Wrong cliche...

Where there's a will there's a way.

I had to use a late 60's style pan for clearance in my car.

The early pans won't work. You need one for an engine with the one piece rear main.

You could get a pan from a 91-93 454SS truck. It's a GenV engine but is also a one piece rear main.
