I reckon they will if they tuck in tightly, but then the engine mounts are different so that may be an unforseen problem. Tower clearance might be very tight. I think spark plugs could be a weekend job. The decks are over an inch taller than a clevo so I reckon the engine would sit at least 1/2” closer to the tower on each side. Best way to determine any fitment issues is to measure the tower clearance on a clevo, get a measuring tape and add the difference in deck height to the top of the cylinder head to the tower at the closest point. Bonnet clearance could become an issue as the manifold and carby also sit higher than stock. You would have to run a carby without a spacer and a drop base air cleaner, unless you like air cleaners sticking out. Sump should be std clevo so a Falcon one should work. I dunno how tunnel clearance will go with the big block C6, but I have heard that 429/460s are a total bolt-in, mounts and all, with no issues noted. I could be wrong on this, but I hope not. I would love to do this swap myself. Sent from my CPH1903 using Tapatalk
