Is a 347 stroker reliable?
Reliability/durability/longevity is all about how you build it – same as any other engine. Some early (1990s) 347 stroker kits got a bad rep for oil consumption due to poor piston design – this had nothing to do with the additional stroke length per se.

What good is a throttle body spacer?
The throttle body spacer permits more air than usual to go into the engine. Thus, the engine does not have to work as hard in order to get the correct amount of air into the combustion chamber. One of the main benefits of a throttle body spacer is an increase in horsepower.
How big is the 92 mm throttle body?
The FAST 92-mm throttle body measured 3.540 inches in diameter, considerably smaller than the nearly 3.70-inch opening in the LS3 intake. We couldn’t help but wonder if there was more power to be had from a larger throttle body?
Is the intake of the L98 the same as the L76?
The L98 had the same intake as the L76 and was equipped with a 90mm Silver blade throttle body up to mid-2009. The blade rotates the same direction as the LS2, but opposite of the LS3 with its Gold throttle blade. This intake isn’t as good as the LS3, so the LS3 is a common swap.

The throttle body opening actually measured 3.698 inches (nearly 94 mm). To get things started, we installed the FAST 92-mm throttle body on the stock LS3 intake. Run with the FAST 92-mm throttle body, the modified 6.0L LY6 produced peak numbers of 546 hp and 494 lb-ft of torque.
Is the throttle body bigger on the LT1?
I’m well aware that the factory openings on the LT1 intake are only 52mm and many claim that adding a larger T.B. than 52mm will create a lot of turbulence and actually HURT performance more than anything. Again, this was done just to satisfy my own curiosity, so bare with me. The throttle body you see below is made by TPIS.
