That's a great idea. You have the parts already so you wouldn't have to buy any hard parts. I have some gaskets here I can send you. I think Rusty made some good points in that post even if he was just kidding. Some here might like to see what a true motor home 440 swap would do. After you are done with your current contest running it in it's mild hopped up version you could change it back to stock. Stock intake manifold, carburetor and exhaust manifolds. Everyone can guess what a true stock motor home 440 will do in the 1/4 in your truck. This test will also tell us what the simple mods you have done already did to improve your times. Most test like this happen in the reverse order but since you already have the mods done you can do it backwards. Something unique. Any changes you were planning after the original test, like for example a cam swap, would require the removal of the intake anyway. I volunteer to donate the prize for the closest guess on the true stock version 1/4 mile time. . Opportunity is knocking, better answer the door.
