I will tell you what impresses me about them the most....The unavailability of blocks....The super high cost of adjustable rocker arms, and how the stroker kits are still over $3k!
The lack of after market companies that make parts for them is unreal. Where are all the companies...They certainly are on the LS band wagon....They have only had +10 years to look at the G3 platform.
How many bracket builds are out there? Hell you go looking for info on these and it is tough to find.
If it wasn't for the few Mopar die hard companies out there, there wouldn't be much...And these are the future as everything else dries up.....
With everyone going to a GM trans in their Mopar, I can't image going to an LS would be too tough of a choice when Mopar parts become impossible to get.
