got the vette back yesterday after full engine rebuild, crank re grind, new flat top hypereutectic pistons, comp cam, edelbrock heads and Dougs long tube headers and side pipes with leg guards. All work done is absolutely 8BBC0496-61F1-46C7-8200-9A53B2F6CA63.jpegtop notch as you would expect from CK. One very happy man with a very loud vette.5710C9DC-FEFC-4876-8451-E84ED4474BFF.jpeg5710C9DC-FEFC-4876-8451-E84ED4474BFF.jpeg945EC719-C035-44BF-8F2C-BA01237A3CB9.jpegE56249A2-A6DB-4CF8-A59F-85566EBB42EA.jpegABD8A538-0C5F-4671-8C9F-44CEAC1F78A5.jpegEE9D1B02-BCE3-4384-8D72-7E0D4DEB432E.jpeg9A2C0A14-351F-4579-BF9D-A847DE8D1769.jpeg70AD272D-4089-4254-91B9-B22A52B6E853.jpeg

Very nice !
Glad it worked out
Good idea going with the dual electric coolant fans
What CAM grind you go with
What is the diameter of the primaries of the headers and

How fast does she go :)

Love the pipes, what inserts have you got in them?
I went for the full fat 2 1/2 sweet thunder. Just done a cold start with a mate holding sound meter 4 ft away 106db at idle 118 at 2.5k. She’s loud. See how it goes for a while May tone it down to 2 inch.

Not sure on the exact cam spec as it was a while ago but it was specd to still allow enough vacuum for the power brakes and headlamps. Still running in but feels strong on short sharp bursts to 3K

Has the ringing in your ears eased yet? 🤣🤣
I drove it to Stonham and back yesterday. Wasn’t too bad once on the move and above 50 . It does sound great but I think it may be just that little bit too extreme for me.
105db at 3/4 of max rpm is the limit for racing. Yours is about as loud as mine was by the sounds of it.
it’s pretty extreme, more so I think at the lower end of the range maybe that’s cos you’re not moving so fast . What silencers did you use in the end to get yours down?

Mines basically got a full system on. With silencers in the side pipes and two boxes under the back where a normal exhaust would be.
