2 questions about conversion I understand that LQ4 and LQ9 iron blocks do not have all the mounting holes that the aluminum blocks have. This limits a few choices for front end drive kits. Can anyone post pictures showing the 2 blocks and the differences? Can these be drilled and tapped?
Question 2- when converting from a truck intake to car intake, can you use the same injectors? Thanks, Scott!

The truck block is missing 1 bolt hole for the lower alternator mounting. Others have drilled/tapped it. Some have just left it off. Sorry no pics.
On the injectors, the standard truck injectors will work in an Ls1 intake if you remove the plastic tip. Flex fuel injectors fit without any changes. The Ls1 fuel rail wont reach the shorter truck injectors. You'll need to use the truck or aftermarket rail.
05 5.3 L59, LS1 intake, flex fuel injectors, $100 aftermarket billet fuel rail.
