Technical Five2 Barrel Setup

On the O.P's o.p. does the cast in firing order read 18736542, or do I need to get my eye's checked?

 

You are correct @427 sleeper , Olds used that firing order on the 303 through the 394’s. They went with the 18436572 firing order when the ‘65 425 engine came out.

 

I bet that thing had so much fuel puddling that the jets had to wear galoshes...............

 

6 cylinders, 5 carbonators, 4 pipes, 3 speeds, 2 wheel drives, go!

 

Some time ago saw a photo of a GM style 5 carb intake, thinking the text stated for a 1964 Oldsmobile. Don't remember if was for the 330 in. Cutlass or the1965 400 in. 442... More info, please... dyno dave

 

Looks more like a later Olds intake to me.... But I could be wrong....
