I don't have any experience with these, but are you sure you have enough oil pressure? I don't think they should be noisy unless they arn't pumping up enough, and that could be caused by low oil pressure.

...length? Maybe you pushrods are too short due to the larger cam? This would cause the plunger in the lifter to be compressed too little and to have excessive lash in the valvetrain (I am assuming you have a non-adjustable valvetrain).

You probably have noisey ones, there is some companies that make quiet anti-pump up lifters, like roades, comp, isky. Some anti- pump ups will make more noies than solid lifters. Ray

OK, the B cam was Ford's grind that they ran at LeMans and later sold over the counter in the Muscle Parts catalogue. It is a variation of the original 427-425 (2-4V) horse Low-Riser cam. It was ground on 106 lobe centers as opposed to 114 for the street cam. Both have .500 lift and 324 duration. The B cam was developed to compensate for the lower octane fuel required in FIA competition that oversaw the international racing rules. Ford had to lower the compression to 10-1 for the 100 octane fuel. To keep the combo working, they changed the opening and closing points of the valves. The Melling # RBL 13 YC (I think) and TRW # TP 143 were ground on the 114 centerlines like the stock factory passenger car cams were. There are other company's that repackage this cam too, as its the standard in the industry. The standard cam (114, 3,000-6,500) idles well for its size. The "B", 3,500-7,000 does not. The ramps are gentle on valve train and valve & seat interface. You can achieve 500 horse with the B cam in a well set up FE. The Medium Riser used the 306 cam by the way, (original 427-4V grind).

P.S. This is a 428. Sorry for omitting that!

Not sure how accurate it is given Ford's inconsistent casting numbers. I use it as a starting point.

The Blue Thunders will outflow the Edelbrock RPM manifold out of the box, and have a higher intended RPM usage range. They have different models optimized for engine combinations, including your CJ.

Where to best buy one depends on whether you want to buy in your own part of the country. Total Performance, Carl's Ford Parts, Perogie Enterprises, and Ford Power Train in Washington state are all good, authorized sources, who have good customer feedback on these manifolds to go by. There are no 'deep discounts' on these products.

...but has not been published in the breakout you requested.

There were 1483 GT hardtop Mustangs in '69, 4084 GT Fastbacks, and 1127 GT Converts. Total Mustang production that year was 299,036.

Also, There were 86+52 R code Hardtops (4spd+C6), 6301+4986 Fastbacks, and 95+222 Converts. There were fewer Q-code Mustangs.

Shoe.

Herewith the most specifc info that I could find of the 428cj website

http://www.428cobrajet.com/production.html

1969 R-code sportsroof with manual transmission: 6,473

I would guess that at least 80% of these were mach1's. Curiously, I see more plain jane R-code fastbacks than GT's. I would guess that there were easily less than 500 69 r-code 4spd GTs cars produced. Get the marti report for the exact number (and don't forget to share it with us).
