I ran a Crower 34416 .21 inches of vacuum,same engine you basically have. 18 degree initial,34 total timing .. (cam specs were 284 advertised,224 at .the 50,and .481 lift with a 1.6. Idled like a stock 340 cam cold,with no choke ,double pumped. Look at Oregon Cams,for something similar, or give them a call.

Hello,& Thanks.. Always enjoy your input,good or bad. Still thinking about class racing?

Happy birthday 273, hope you have a great day today!! Enjoy!! Geof

Where were the Canadian barracudas build?

Sorry jh66cuda never heard of that one, couldn't even find the specs when I googled it.

Have you ever heard of anyone putting a Melling 23203 hydraulic cam in a 66 273?

Merry Christmas to you and your family.
