I guess this is mainly just because I am wondering, but what is the difference in part numbers here?


both of them are for the CT4 Blackwing but one costs $2600 and one costs 12000 (before core charge)

I know the manual one has different connecting rods, But is the automatic LF4 engine really only 2600 bucks? would make me more comfortable with modding it haha.
 
My honest opinion is the first one is missing a 1. Definitely a typo
 
Those two part numbers are correct. The only difference is that the second one has Pankl titanium connecting rods.

Note that both of these part numbers are for M6 cars. GM doesn't offer replacement LF4 short or long blocks for the A8 or A10 cars, so you'll need to swap the oil pan for proper fitment in those cases.

wow that is crazy the titanium rods make it a 10k difference.
 
Yeah but isn't the difference between the LT4 and crate LT4 just the supercharger?
Based on the pictures, there's more differences than just inclusion of the supercharger.
 
Does anyone know the correct part number for the ct5 bw engine block? Want the same block part number and punch it to a 416
