Whoever told you that is an idiot! Only had 5.7's. The 3rd gens F-body's you could get in a 5.0 305 but from '93-'97 only 5.7

There is a 4.3L version of the LT1, is externally the same except for casting numbers.

Was the base engine in the 94-6 Caprice sedans only be they police or civilian cars.

The option code for it was L99.

To further confuse matters they used a "W" VIN code which was the 4.3L V6 code.

HUGE amount of missinformation out there on this.

The only way to make a "stock" (via factory parts) LT1 down that low is to use a 4.3 Baby LT1 crank (with 350 rods) in a 5.7 LT1. That makes a 4.9L (302cid) motor. Use the 4.3L crank AND rods and you get 5.3L. Only benefit would be it being quite the rev happy motor and a flatter tq and hp curve heh Side effect would be quite a big hit in torque.

One of the Impala guys did that with my old L99 crank and rods for a 302 with stock LT1 pistons and yeah it sucked.

Must be a typo that you think rods affect displacement?

I never knew about the baby LT1, but I never researched Caprices.

he must be talking about a 3rd gen where the 5sp only V8 motor was a 305(5.0L). Maybe the 3rd gen verts too but not sure on that.

Thats a LB9 TPI motor though, and VERY different looking than a LT1.

Let's be clear. You think some sort of math causes changing rod length from 5.700" to 5.940" changes displacement??

Let's play math class and show your work?
