Roller cams make more power for sure because of the lift area under the lobe, for a given lift and duration the roller will be open further for a longer duration, and you also get the benefit of reduced friction with the roller contacting the cam instead of relying on a flat tappet's face...

...why you cant accomplish what you want with a flat tappet cam...however with all the horror stories out there about bad lifters and current cams losing lobes i think the roller is a $500 insurance policy by the builder that the thing is going to stay together... there's a you tube out there...

...rear axle from the rear of the transmission, too. Might need to emulate the '65+ system to do that? Might stay away from the "Purple Stripe" cams, all things considered. The original "Purple Stripe" cams were a good bit more radical than the stock cams were back then. As in the "Street...

Crap! Now I'm worried about mine. . .

Where does it say that?

IMHO, the best of both worlds is a rebuilt US built Mopar electronic distributor with the GM HEI unit. @halifaxhops sells a version For Sale - a B and a RB rebuilt electronic distributors with HEI I'm not a fan of the new Mopar ECU and distributors that are manufactured in China. The...

Not so with bushings. The alignment adjustment on these cars was with cams on the control arms that absolutely must be dismantled to get the control arms off, it's quite doubtful you will get them back exactly where they were.... I was an alignment guy for 20+ years, still so some front end work...

...flat tappets need to turn as they go up and down to minimize wear, which is what the crown does. You're worried about flat tappet lifters and cams, I have seen the many videos on the Gen III Hemi lifters, plus knowing about the multitude of OEM lifter failures on Chevy roller-tappet engines...

...sir) The cam in this engine currently probably has the 256/256 or 252/252 cam. hopefully. Something similar not interested in rowdy loping cams, I figured a little bit bigger like a 262/262 cam with 113 LSA? Rear gear I've been pondering on Maybe 2.76 or 2.93's? But that's another thread or...

...and needs replacing anyway. JR Imports carries all laminiated glass that can be cut down for a chop. For power I have a Jaguar v12 with race cams lying around. Found some squarebore intake manifolds for it. Dual quad v12 Meteor, why not? Gonna enjoy big blue all summer then go pick up the...

If your 383 is not using oil/blow by I would do a cam swap. Those early 60s cams are pretty lame. If you have the 284/484 cam well you own it, but you can do much better. I personally dislike that 284/484, the 292/509 cam is waaaaay better. The stealth heads will bolt on and put you...

There is a whole plethora of opinion and debate on the wiping of lobes on flat-tappet cams in classic car engines. I recently read a lot of lifter-wiping and oil/zinc stuff. An interesting comment I read on the Comp Cams issues - 'Comp sells more cams than anybody so they are bound to have more...

...As I mentioned, Dodge was more open with that information. Back then, that would have meant nothing to us as to what was in the motor, as to camshaft. The question would be "Why the change in 1970?" In looking at the various equipment specs, it makes me wonder just how much more power the...

The manufacturer of these cams is Shee-Mar. Their calatog lists the SM-15 as the correct replacement, but it only has two wires. The third (purple) wire is for cornering lights, so SM-15 is only for cars without cornering lights. Unfortunately, Shee-Mar doesn't list turn signal cams for cars...

Some detailed volumetric measurements, optimized for the performance band you seek help make a decent first pass at optimizing for both quiet and High Performance. That's how the old engineers at Ma Par, GM and Ford did it during the Golden Age, using naught but their slide rules, cigars and...

The horns were probably unplugged due to the horn switch on the Rim Blow wheel expanding and self-actuating the horns. That is what mine did, when the interior temp got over 80*F. The dealer told me the horn did not work when I bought the car. When I diagnosed the situation, I found a...

...Basic orientation of making the "air pump" a better air pump. Getting air into and through the system. Lunati used to have a selection of cams which they had "made better" than the prior factory HP cams. The particular one which a few members in here was the "reimagined" Chrysler HP cam...

...idles a lot the Zinc is more important. New cam and lifter interface needs high zinc to build up the protection that zinc provides. Aggressive cams and valve springs wear back through the built up protection layer quicker. A stock engine with many miles on it, and not using it for parades I...

I have a brand new set of Lunati lifters in the box on my shelf because I had 2 different sets in my shopping cart online at Summit and forgot to remove one after making my final choice. What a surprise when they showed up!:rolleyes: The one currently in the silver car?
