RE: stick with it Bob! |

I've been doing a little reading tonight. Before I got back on here. Here's what I think I know. Just like you say Bob, the '67 428 PI got the GT hydraulic cam, C6OZ-B. I'm assuming the '68 428PI stuck with this cam too but I think it received a cast iron intake. I shouldn't say that because it may open a whole new can. But that's what I like and how I learn and refresh the matter. As for the mighty Shelby GT 500, yup, it received the new & "improved?" '67 PI 428 with hydraulic GT cam. They just bolted on the C7ZX dual quad intake w/Holleys. There you are, 355 hp.
Here's something I'm looking at that does add support to your '66 shop manual source: It's S.Christ's book, page 85 where he shows cam specs. I totally forgot about this page! But there it is, the '66 428 PI having the same specs you've indicated. Same specs for the '63-'67 427. Then the '63 - '65 PI 390 cam has the milder specs that Royce indicates which are also the same for Marine apps. 352 & 390.
Now it's all straightened out for me. I'll sleep like a baby tonight.
I found page 85 in a book I've had for 18 years! |
