Magnum dyno videos
The Base is the 300hp crate engine which is a stock 5.9l Magnum with a 4bbl intake M1 dual plane and 750 holley and headers.
Seems about right with his 288 hp with beer barrel and manifolds. 300hp with headers imagine 4bbl intake for another 10-20 hp.
(The mod is eddy heads air gap and a Comp 275 cam)
Here's different exhaust.
