Today, dollar for dollar, is the 318 faster than the 340 ???

I'm not back pedaling 5.2 magnum stock freshen will support 400hp. Just the facts

Magnum heads will support 400hp out of the box. The 5.2 magnum already has higher compression than the la 318. If mopar performance can get 400hp out of stock magnum heads and a stock bottom end then its already been proven to work. So 5.2 magnum has factory heads that with a spring change can and will support 400hp. So just because you don't like it doesn't make it untrue. You have been presented with facts. And your return replies are always baseless flop jawing about how you do things. And you still haven't provided any facts or numbers that prove me wrong.

Break down the hp numbers, machine work you deem necessary. Prove to me that a 5.2 magnum with just a cam, headers, valve springs and intake can't make the power I stated. Prove it show me the numbers or you are the one blowing hot air

So you have built this 400HP 318 for $3000? What did it run, 1/8 or 1/4?

My 340 was .030" over, ported Edelbrocks, 11.4-1, Weiand X-Cellerator intake, Hughes 236/242 @.050", .580"ish lift IIRC hydraulic cam , 750 Quick Fuel, 727 with a 9 1/2" converter that flashed 5400, 4.30 gears. On a 275 radial it ran a bunch of 7.24 @ 94 in the 1/8 and 11.60 @ 116 in the 1/4 @ 3240#. These are real world numbers, not it should make ***, my buddy knows a guy who....... or inflated magazine builds.

I'm not saying a 318 or 5.2 can't make 400 hp or run 11's because they can, but it's not as easy as bolting on headers, intake and changing the cam. If that were the case you'd see tons of them at the drag strip on Saturday nights. Don't even mention stockers or super stockers because they are a breed all their own and you will not see guys who have $3000 budget running one any where near being competitive.
