What cam are we talking about?
By Mike McQuesten - 01/11/2002 12:31:21 AM; IP 63.50.124.230
Nick asked a good concise question with regard to a C6ME-A block. I give some muddled answer where I start talking camshafts. Mikeb gives me a descent response and I start thinking all about PI cams, HP cams and 427 cams. Bob tells us about his '66 PI that he ran the 427 cam in without any consideration for hydraulic lifter passage blockage. So I just have to ask a few things and I know I'll get a response or two 'cause I'm going to throw in the name Shelby.

First q's: Which exact camshaft did Ford use in the 1966 428PI?
I don't believe it was the 306d/500L shaft. My theory is that it was the same mild solid lifter version that was used in the 1965 last 390/330 horse PI. I'm looking at a little Ford brochure right now titled High Performance Equipment Owners Manual. It tells a little about the 289HP, the 427 and the 390PI. It's a 1965 publication. It gives some cam specs and mentions that the 390PI has a cam duration of 282. However, they also say that the 427 has a duration of 324. Well, we know that the 324 cam was an over the counter shaft. The standard automotive '27 solid cam for all those year was the 306/500 cam. So what is this 282 solid cam? Was there a special grind marine camshaft that saw 390 PI useage? Was it the same 390PI cam as used in '63/'64? I'd like to know.

Second q's: Was the '67-'68 428PI cam the C6OZ-6250-B 390GT cam? I know for a fact that the '68 428 PI and Shelby GT500 428 engine were the same and that they were hydraulic liftered. I do know that the earlier GT500 of '68 wasn't a KR which got the Cobra Jet. How about the '67 PI?

I thought the '67 428 PI was still a solid liftered engine like the '66. But I'm right now looking over at a '67 Full Size Ford/Merc shop manual that gives the cam specs for the 428PI as Lobe Lift: .278 - I & .283 - E with theoretical: .481 - L & .490 - E. Do those specs look familiar? Lets look at the '67 Shop Manual for the Mustang & Cougar. 390GT cam specs: yes indeed, exactly the same as the Ford shop manual listed for the 428PI. So that would tell me that the '67 Ford 428PI ran the 390GT cam.

Okay Fortunate Shelby owners, what camshaft did Carroll allow to be used in the '67 GT500? I had assumed it to be the exact same cam that was run in the '66 428PI. For many years I thought it was just the old trusty 306/500 cam like Mikeb told me. Is that true? Did ol'Shel just have the mechanics install a very cool C7ZX dual quad intake right on the standard '66 428PI?

I don't know why these things matter to me. They just get me thinking about these useless things and I can't stop until somebody here sets me straight.

I'm so nuts I just ended up "winning" a set of Isky FE solid lifters on Ebay! I do have an old Isky 505B, hardface thumper that will fit only old FEs '62 & back. I guess I think I need the lifters to go with it?

Thanks.
