Ok so I got a LS1 drivetrain out of a 2001 trans am for my 79 Monte, I have read that the f body pan won’t fit without notching the crossmember and I’m not looking to go that route. So what pan fits good with the ITC Billet swap plates ? I have been looking at the Holley replica pans but not sure how well they will fit my application or which part # suffix to buy. And I’m sure it will get mentioned so I’ll put it out there not looking to buy the Holley kit with mounts, pan, and crossmember. Spent my swap budget on the drivetrain so I need to watch my spending
