There is approximately a ~7/16 difference between bellhousig extension and crank flange between the LS and SBC. The LS is shorter, the SBC is longer. Also the position of the cylinders relative to the bellhousing is different. The cylinders in an LS block are also approximately ~7/16" closer to the bellhousing. This means the cylinders are actually ~3/4" close the transmission in an LS motor than an SBC. So even with a longer water pump on the from, they still have similar or better radiator clearance.

The way you've done it, is the motor as far back as it'll go without firewall interference?
