Default Chevy vs Ford comparison on PowerNation TV

Interesting comparison on a TV show.
The comparison was actually two episodes back to back.
The premise was to take an LS based cast iron block truck engine (LQ4) and compare it to a similar Ford Winsor based truck engine.
Do baseline engine dyno runs and add similar performance parts to both and see where they end up.

It feels like the same discussion that happens on here with respect to potential V8 Miata powerplants.

In case you don't want to watch the episodes bottom line was that the truck camshaft is far and away the limiting performance factor for both engines.
Both were set up for old school carburetors and similar headers and intakes.
Probably the biggest difference was the compression ratio as the Ford was way down there at around 8:1

They did not specifically equate dollars to dollars but it appeared to me that building both engines would be around the same money as the same parts are switched out for both applications.

When the dust cleared the Ford gained more HP from the add-on's but the Chevy engine made almost as much horsepower stock as the Ford engine made with all the changes.
Dollar for dollar there did not appear to be any real comparison with the Chevy being around 130 HP ahead at the start and still 100 ahead after it was all over.
