427 Lingenfelter
Just got my C6 transformed by 21st Century Muscle Cars. Dropped and LS7 427 into that thing and the Dyno numbers just revealed 535 rwhp with 510 rwtq. 615 at the flywheel....
only problem now is how to find a way to use 1st gear again. Happy in Texas....

Congratulations! 21st Century Muscle Cars does great work and is tremendous to work with. I'm extremely pleased with my LPE 403 and the other mods they did for me.
If I'm not mistaken, the LPE 427 package is also a 'built' forged-component motor....the only way to go IMO.
I think they also put on some kind of headers with the 427 package but did you do any other mods....suspension, exhaust, etc.? Do you notice any appreciable difference in the 'feel' of the car (other than the obvious
) or handling due to the weight of the 427 block?
I understand your 'being able to use 1st gear again' statement. Although it's satisfying to be able to light 'em up whenever you want, I'm already planning my next trip back to 21st CMC for a few other mods....including some to help the car hookup better.
Congratulations again....great choices all-around!

Pictures
I am fairly new to ths and don't know how to post a pic. Give me some instructions and I will put a few in here
then you highlight the picture address stuff by making it blue(right click and drag over the info) then right click and "copy".
Than you come here and go like you're posting a message and click on that thing up there with the "sun and mountains-yellow sky in the box-when the box opens you put the picture address info in it by right clicking and hit paste.then hit ok and you're done.I hope I explained that correctly.
