I had a few of those tbi 318-360's over the years, and found them very reliable but not as powerful as the magnum series. Roller cams and roller chain-gear sets were on many of them too.

The Magnum angle is pretty much vertical, where as the LA is more like 45 degrees. The ends of the Magnum heads are a bit different than the LA's so you will have to mock up and rework the accessory brackets to fit. Doing this on the engine stand is the easiest way. Magnums use a different external balance weight, you will have too address that as well. The Magnum does not use air injection so you will have to seal those ports in the manifolds if you reuse the LA manifolds. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

The necessary intake can be had for about $300. You can probably use your factory fuel pump with a regulator and a return line. The tbi was a great running engine but was sadly lacking in performance. It'll get you around town forever but don't expect much enthusiasm. The 5.9 Magnum has a lot more power and performance.

Other than that, there isn't much you can do to get more power without upsetting the tbi. There's always the carburetor approach or aftermarket EFI. With either of those the sky is the limit.

The easiest way to do this would be for you to get an aftermarket intake manifold. They make carbed intake manifolds for the magnums. You could fairly easily mate the tbi to the carb intake. Do not try to put the tbi on top of the magnum intake. Those are designed for dry flow only.

I think the LA water pump is required also. Not sure what dists yours would have but if needed a common LA 70's electronic dist would drop in live every 24 hour block of time like it's your last day on earth

It's $285 with free shipping. Stuff a regular distributor in the engine. Pop a fuel pressure regulator on it to bring it down from 15 psi to 7. Drop a carb on the intake and hit the road. Keep the front end of the Magnum with the accessories. They're good pieces. We are brothers and sisters doing time on the planet for better or worse.

I'd think it's quality would be better than the crosswind tho I hear they have taken care of alot of the casting issues the early production ones had live every 24 hour block of time like it's your last day on earth

Keep the front end of the Magnum with the accessories. They're good pieces. The OP asked about keeping the TBI. If he goes carb he'll need to address the kickdown and throttle linkage setup. I no longer remember what the TBI setup used and if it's adaptable to a carb. But I'd bet it's closer to the 2bbl than 4bbl setup. They say there are no such thing as a stupid question.

A used magnum engine would be in way better shape and offer some hp improvement even if the tbi is retained. If it wasmmine and an everyday driver and peak ho is not the goal, i would keep the tbi.
