MRL Performance 340, WOW!

Well, if you can look at it this way, the heads are likely flowing numbers like a stock LS1 chevy, we got the rotating weight into the ballpark, run a similar cam size cam for one of those, not uncommon to see 400 rwhp and 370 rwtq from a combo like that. The whole idea behind building the engine this way was to use a lot of the ideas you'd find in a more modern engine. It's also a car that won't ever have drag radials or slicks on it so building a stroker motor would have only turned it into a burnout machine.

Comparing this to a flat tappet cammed motor with stock rods, double springs, and TRW L2316F's isn't even a fair comparison. There's a lot more area under the curve with a roller cam of the same duration. This thing also has great quench. I know we took at least 800g out of just the rods, and a ton more out of the pistons vs stock.
