Seeing as the boss is not home yet I had a chance to look this up.

I hope it helps?

I have the correct formula for Hemi Orange somewhere at home. I will see if I can find it tonight after American Chopper.

Decreases engine life and uses more fuel etc etc. I did say performance car ! You don't get something for nothing. :wink: Mind you the piston rings wear out faster on a longer stroke. But hell. in this case it is only a little bit of a longer stroke. I was just talking in general terms. I did also s...

Funny enough I was standing next to Trev looking at this engine and I said "I think it is a mid-70s truck engine Trev" (or words to that effect).

Nice to know I can still do a good guess!

The drawback to making torque at lower rpms is it limits your speed. At least that is the way I see it. Fine if you want power at street speeds but hopeless if you also want a high top speed. Those cars with a high power band you were driving did not have the right gearing for the engine. But then a...

Mechanical losses are made up of stuff like piston ring friction. A long stroke adds to that. Other factors are bearings and seal friction, valvetrain and spring pressure, accessory drag, pumping losses (dragging the air in and compressing it) etc. The losses induced by these things increase with en...

Work it out yourself college boy! :lol: The average speed is easy. 4-inch stroke (as an example) is the distance in one direction so it goes 8 inches in one revolution so speed = 8 x rpm. So at 6000rpm you are talking 4000 feet per min (average in the bore) It must be faster than that in the middle ...

Sounds like a great engine. A mate of mine needs a crank for a 360 so I have talked him into going the 4-inch stroke route for 408 inches. The only drawback to a long stroke is piston speed. The longer the stroke the faster the piston has to go to get from top to bottom (and back again! :) ) in any ...

The factory units are very inaccurate anyway Steve. Just an ornament really.

I don't know what year car you have so this is general. Normally you have three or four wires out the back of a tach. One is just for the bulb so ignor that. One maybe an earth or it may earth through the body of the tach. There will be two other wires. One (power lead) gets connected to the battery...
