Big Block VS LS Supercharged Slugfest! Which One Makes More Power With The ProCharger?!


Big Block VS LS Supercharged Slugfest! Which One Makes More Power With The ProCharger?!

The LS engine has done a ton for the automotive aftermarket. Period. Love it or hate it, this little engine has spawned so much parts development over the past decade or so that it has spilled over to other platforms. Companies like Holley have put so much into EFI development that this is also spilling over into being useful on any engine. This has happened with lots of products, but despite this there is still a major debate that you hear in the racing and hot rod community about whether an LS or a Big Block is better.

Now I happen to be an engine fan in general. I own LS engines, small blocks, and big blocks. I like them all. I like them for different reasons and I think they all have their place. With that said, the emotional favorite for me will always be a big block Chevrolet. After all they are THE premier racing engine  and always have been. Take top fuel out of the equation and the quickest and fastest race cars of today are still powered by a big block. And before some of you say, but what about the 481X, that’s a big block Chevrolet based platform and is my point.

But which is better for power? Which likes what combo best? Well that is a question that will be debated from now until forever, but there is at least one more video out to stir the pot with. This one is from our good friend Richard Holdener who is the testing master. He spends his time running engine after engine at Westech Performance Group and we love him for it.

Watch this latest video and let us know what you think. We’ll have tons more coming from Richard in the future and we are sure they will inform, enrage, and entertain.

    Yeah, interesting video but his conclusion at the end is flawed. For an apples to apples comparison the blower pulleys on both engines should have been the same size. To say the the LSX engine “won” when a smaller pulley was used is unscientific and downright laughable. It appears to indicate bias by the tester more than anything else.

    I will say that with all things being close to equal between the two engine platforms the LSX does have advantages in both lighter weight and a smaller overall size for packaging.

    It would be interesting to know the bore and stroke numbers as well as the rod length to stroke ratio of both motors.
