The truck has been on the road for the last two years. I need to pull the engine to repair a few things with the steering and replace a seal. Thought as long as it is out, perhaps a replacement engine is in order. The current one works okay, but as long as everything is out.... So I have a line on a 318 magnum. If I go the carb route, I need about $300-$400 for an intake and carb. What's the story on drilling new mounting holes in the magnum heads to accept the LA manifold and carb? I have a cast 360 intake and a very nice carb. Not sure on the part number, but it's larger than the 318 carb. Would this work or do I need a 318 carb? Could I use a 360 TQ if I knock off the weights to use in the 727? Merry Christmas!!
