Ok folks. Engine has been back in and running a couple of weeks now, and all is well. About 30 miles completed so far .
In celebration, got a complete custom exhaust made up with Vbanded 400 cell cats so I can run with or without.
Mapping is happening this Saturday and I’ll map with and without cats .
The exhaust was done by Longlife to my spec , Hpipe ,because personally, The LS1 sounds best with an H pipe.

The car made 442bhp on the old set up (at srr) so now I have no valve overlap and ported 243 heads. If it makes similar figures I’ll be happy.

Looking good!
That'll be a good output from an LS1
