There's some stuff in here worth noting.

Sweet article. I wonder what the cost was, counting his hours.

To replicate...quite a bit.

It seems what's written here is contrary to the accepted 'common knowledge' around here regarding hydraulic rollers and how they don't rev.

Seems the Key was the lifters, I did notice that it did peak about 6500 so the added rpm range of 7500 was a bit over kill I thought.

It reved to 6700 w/ traditional lifters before having any issues. The limited travel lifters extended the rpms from there.

The key was the hollow stem valves. There are other things that could've been done before going to those lifters as well.

It did peak at 6500, but it held the power pretty well beyond that, which is common for induction components that are sized correctly...ie not stock heads. The importance of reving beyond peak is to get an idea of what the appropriate range to shift the thing. No sense in shifting at peak and letting the rpm drop to a point where it could've made more avg power by holding it in gear another 500 rpm.

Over my head.

Never too late to learn...

I'm learning. But I've got to learn bumper to bumper, roof to tire, and carb to oil pan. But I do know where the gas goes!! lol.

I read these articles and car stuff as much as I can. Takes awhile when you have to google every part. Learned about torque converters last weeks. Pretty nifty. This article made me look up 2 bolt vs 4 bolt mains and girdles.


Oh I learned about quench last month and with my 340 I decided to go that route. All because you and the rest of FBBO post up stuff like this.
So thanks again for the link.

Yeah that's how i determined the best shift piont for my bracket cars. I would figure out the range that made little to no differance and then pick the RPM at about 60% of the band. So if it was between 6200-6800 I shifted at 6600 so if I missed my shift a little it had the least impact on my ET. Good stuff!
