If only we could help DWomby with his dismal consumption! If I recall correctly David struggles to get into double figures with a 360 cid engine? Makes my own tribulations seem small. I looked up the cam specs of his Mopar Performance 4452761 and they don't seem too outlandish.
So wrong timing/timing curve? Vacuum advance missing/not working? Cam incorrectly installed? Carb leak? Other leak? Fuel evaporating? Engine fault? Over-rich carb? Blocked air filter?
You do recall correctly although most of my driving is suburban. So higher numbers may be possible on longer runs. Unfortunately, my car has been off the road since late last year while the front suspension is out (see the saga so far here: http://www.bristolcars.info/forums/8...r-removal.html

I expect to start reassembly in another week or two when temperatures and humidity here have made working in the garage possible. I hope to get her back on the road before Christmas and the fuel consumption/tuning issue will no doubt need addressing then and I'll welcome all help!

David
