Schubeck lifters

[Jeff Teuton]

Just for information, I have a proposal into NHRA to allow aftermarket rollers in lieu of flat tappets. Why not try to get some folks to work on this. There has not been a flat tappet since the early 80's and I pointed that out along with only one manufacturer in the US. I know we squabble a bit, but those things are bad ancient unlike most of the old cars which are good ancient. Bruce, jump on that and get the troops to emailing CA and the Divisions. It's time for a change on that.

With all the problems that racers have had with the Schubeck lifters why does a lot of racers continue to use them? Their just asking for trouble! How many has Schubeck replaced?

Basically, you would need a cam ground straight across the lobe for roller lifters,not tapered for flat tappet lifters, the rollers, the link bar, what about a rev kit to keep the rollers in the block in the event of pushrod or rocker failure?Sounds like a good answer to the recent problems that have surfaced. I feel that a rational,sensible appeal to the tech department with this proposal is in order. So many 305 and 350 blocks are machined for the factory roller set up already,as is the Dart block. Seems to make sense that an aftermarket design exists for the OEM earlier blocks as well.Meanwhile,converting from ceramic base to tool steel lifters sounds like a good way out.

Wow, that sounds radical. I can't wait to hear what a 396 375 sounds like at 10000 RPM.
Since we are On that path, I think we should open up the valvetrain to Titanium valves and retainers. Don't forget clamshells on the camshaft.

This is just asking to get out eleminatior merged into superstock. I'm not interested 2k in new valvetrain parts just to keep up. NO THANKS. If you keep breaking stuff, spend money and do some spintron testing. Or buy a new car, and you get all that already.
