One thing leads to another... mean 318?

Don 't get carried away with peak horsepower! My 410 years ago made 355 rwhp and my sons LS made 460rwhp.Mine was quicker than his. The dyno operator showed me why.
Mine made 345@ 4000rpm 355@5000rpm and 345@6000rpm. That's only 10 hp difference over two thousand revs. His LS @ 4000rpm probably only made about 280 rwhp but made its 450 @ about 7000rpm. through a certain rev range He said average HP is what it is all about not just peak HP. V8 supercar racing in Australia learnt this as When the Nissan and Mercedes engines came in the category everyone thought they would be rocket ships but were always getting beaten coming of corners even though they made more peak HP than the pushrod V8s of ford and chev. They bought new rules in and instead of a peak HP limit they designed a system were the engine were dynoed through a certain rev range and were only allowed to make a certain average HP.No good making a peak number one hundred better than everybody else but your lower revs were crap!

The dyno operator was dead wrong. Your combo was quicker because the chassis /converter/gearing in your car was better suited to the power curve.

Fix your kids car and it will gap yours. It’s simple really.
