yea, but that is rated at 145 horses at the flywheel ...I am pretty sure.

The later ones show 100- 105 horsepower in S.A.E. net which I am pretty sure means at the rear wheel.

The slant always had the same compression.

So I would bet new, my 68 slant could do maybe 100 but its tired now and worn out so 80 would be awesome

SAE net hp is measured at the flywheel but with additional requirements.

SAE HP - required a standard production engine be taken at random off the engine line, equipped with oil pump, water pump, fan, distributor, and generator/alternator. It also had to have standard exhaust manifold and header pipe in place.

SAE Net HP - all the above, PLUS all standard accessories found on the average model the engine was installed in. It had to have a full exhaust system, standard air cleaner in place, coolant in circulation and be measured at standard operating temperatures as found in the average model it was installed in.
