How much horsepower does a 351m/400 with a 268 cam, Edelbrock highrise intake, Edelbrock 4bbl carb, all MSD wiring,plugs, and 6" box, with 3" exhaust have?How much horsepower does a 351m/400 with headers, 268cam, Edelbrock highrise intake, Edelbrock 4bbl carb..?
They rate horsepower at different rpms. That same engine in different cars could be up to 20% different due to wear, assembly, crank or many other things. They only true way to know is to have vehicle, or motor put on Dyno. I had that same motor years ago, and if I had to guess I would say close to 325hp.How much horsepower does a 351m/400 with headers, 268cam, Edelbrock highrise intake, Edelbrock 4bbl carb..?
You didnt mention the heads..... if you have the stock heads and stock compression of lets say 9:1 then I would say 250HP.... with big valve heads and 11:1 or 12:1 then the HP goes alot higher.How much horsepower does a 351m/400 with headers, 268cam, Edelbrock highrise intake, Edelbrock 4bbl carb..?
Desk top dyno says 295 HP @ 4500 rpm is the peak .
Thats with the low compression dish pistons . Flat tops will bring it up to 320 Hp . This motor puts out close to 400 ft pounds of torque . Thats what gets a big car/truck in motion .
Around 400 horse power.
