Huh? Even if you do all that stuff you're still missing about 80hp/100 lb/tq compared to a stock 2barrel 318. About the hardest part of doing a /6 to 318 swap is getting the lopsided lump out of the car without trashing the bulkhead connector, after the 1st time you learn to disconnect it and push it inside the car. On a 67-72 A body a /6/904 to 318/904 swap shouldn't take more than 1 day, if it does you're doing something wrong.

Comparing factory net hp ratings, there's only 50 hp difference, stock to stock.

Thank you for that tip. Why would you trash the bulkhead connector? The engine leans the other way. "Everybody funny, now you funny too."

No need to keep ragging on slants, though. Slants have been good, solid, reliable engines for 40+ years. And my mildly-modded is anything but slow. But hey, if you break the bulkhead when you pull your engine, it's the engine's fault, right?

I don't even pull the hood off my Valiant when I pull the motor. Just a question for all you 318 guys. How many Hemi owners have been afraid to race you for money after they saw you make a pass at Monster Mopar? I know Slants aren't for everyone, but that isn't the motors fault.

I just now located a '77 Aspen wagon the guy is using for a daily driver with a 318/904 and will sell to me for $500. And, another buddy has volunteered to haul the body to the scrap yard for me.

They were only light on power due to the smog equipment, which I don't think would be following over with it anyways. 1987 Fifth Avenue - 512/518/D60

However, it is still gutless. So, I had my wife floor the gas pedal (engine off, of course) while I looked down the carb throat. It doesn't even go to half throttle. After inspecting it some more, I discovered it has an incorrect throttle cable on it. In fact, it looks more like an aftermarket transmission kickdown cable adapted to fit. Anyway, I placed a parts wanted ad on Moparts last night and have already gotten several responses. Thanks Moparts. Your life is not my fault. My life is none of your business.
