400 hp 5.2l vs 5.9l Magnums

Or you can look at it this way. To gear the 318 to do the same job as the 360 would require an overdrive trans.

Not knocking a 318 build at all. Just apples to oranges comparison being made thats all.
Of course it ain't apples to apples parts are slightly different and displacement is quite a bit different but the results are surprisingly close by what most would assume.

No question larger engines are generally more streetable with similar performance.

All am saying is if geared, stalled correctly for maximum 1/4 mile performance it would be close.
