Alright, so the story is that I don't have a knowledgeable Mopar mechanic available in my area. Period. After all this time, and money spent, I now know that I have a 318 Poly under the hood of my Heinz 57 with what I believe is a 435 transmission with hydraulic clutch. All this time we've been operating under the assumption that the engine was an LA318...that was fine until I tried to change the intake to mount a 4-barrel because the Holley 2280 is shot. Needless to say, it didn't work. SO, I have a couple options to run by you:

1. I have a 67 parts truck with 34,000 original miles. That one is FOR SURE an LA 318 (Now that I know the difference I feel very stupid- it's obvious). I was told I could
a) swap the carbs
b) swap the engines

2. Option 2 is that I have access to a 76 Cordoba with a 360 and Torqueflight tranny with 45,000 original miles. The question here is if I can slide that LA 360 onto that 435 without much modification. I know the 360 is externally balanced and may cause a problem, but what else? What other information can I provide you to help make this question easier to answer? Thanks all!
