One thing leads to another... mean 318?

A 273 will never ever make the power of the 318 or 340 because the bore is so small. This example is a perfect of why bore size matters. The three above examples all share the same stroke, deck height and rod ratio. The bigger the bore, the more power they make because you can run a bigger intake valve and a bigger intake port and manifold.

Thanks. You now agree with me and disagree with 273.

That’s a very good example. You’ll never get the valve sizes you can get in a 273 that you can get in a 340 and that’s where power comes from.

Valve sizes aside, equippe a 318 and a 360 with the 1.88/1.60 combo..... or equippe the 273/318/360 with the 1.78/1.50 combo, what does they crystal ball say then, ehhh, screw the crystals; ball, what does your head tell you!!!!
