Give it a tune up, change all the spark plugs, the plug wires, even the coil pack or packs. If that doesn't work you'll need to perform a compression test on all of the cylinders and see if you have a cylinder that isn't building up proper compression. If my memory serves me, that engine is a Distributorless system that uses three coil packs to fire off the 6 cylinders. One bad coil can kill two cylinders. I had an ex GF that had the same issue.

What is the engine capacity horse power for a 351 ford cleaverland .

351 "C" 4V 1970-1973 Cleveland
would have thought engine capacity would be what they wanted
351 cubic inches which converts to 5.75186 litre capacity
horse power in the link above is 300 BHP (brake horse power)

I have no idea myself but found the car memories web site that states the engine specifications and I hope it is correct and matches your engine ?
most likely it would be rounded up to a 5.8 litre capacity

What causes low acceleration

low horse power.. such as a 2.0 engine does not produce as much horse power as a 5.9 engine.. but it could also be caused by low fuel pressure or friction with the pistons in the engine not being properly lubricated..

Is horse power the same for gas engines and electic motors

Yes. Horsepower is simply a measure of power, usually considered to be equivalent to 746 watts. It doesn't matter if the power is coming from a gas engine, an electric motor, a hamster spinning a wheel, or a horse.
