LET ME KNOW WHAT YOU GUYS THINK

 

nice C5 and nice numbers.....sounds great too

 

thanks

 

Numbers look right where they should be. Add some ported heads and a Fast and welcome to the 450+ club

 

Great exhaust note...and I love that torque curve! Bet she's a lot of fun on the street.

 

nice #'s

 

yes very nice highway car

it tears

 

Those are some good numbers.

 

 

Great numbers there! I bet the car rips now! You planning on doing gears?

 

thanks

ya either a 410 or 390 havent decided yet

 

Go for the 4.10s, you won't be disappointed! If you had a Z06 with the M12 gearing, I'd say you might want to consider slightly longer gearing depending on your plans for the car, but with the 2.66 gearing you should be VERY happy.

That car must haul ***! Nice numbers!
