The ring and piston material, along with NA or pressurized, will make a big difference in what should be used

Re: Airflow loop to help oil drainback

In some instances, don't put breathers in the rocker covers but, breath the crankcase from the valley.
When blow-by air is forced up the drain-back hole to breath through the covers, oil can not get down through those holes easily..

Re: Finding some more ponies

The engine made very good power(662hp@6650) for what it is but I am looking for ways to pick up another 25hp or so. Another 25 hp is 3.7%, almost down to the level of dyno repeatablity and correction. It's doubtful if you could feel the difference on the street. Supercharge it was a good suggestion...

Re: Opinions on removing crank counterweights

WoW ... A flathead 4 cyl Model T.

Rotational balance is not the only criteria to balance. "Radial" and "Axial" need those counterweights just as much.

Re: Question for the BBF guys......

Just a little follow up with these...... I ended up cutting the valves down to 2.23/1.73. The seats had already been machined for the 2.25/1.76, so a little sinking was required to accommodate the smaller valves. In the end the seated valve to valve clearance ended up at .060”-.065” with the heads ...

The "N" heads were iron and 10 degree valve angle.

Re: Mahle bearings...run em’?

Most of the time ... getting the correct amount of bearing oil clearance is much more important than the actual bearing.

No issues. this one has roller camshaft bearings, which I am unfamiliar with. the paperwork shows journals 1-4 are 55mm, and journal 5 is 50mm. Is this the standard way roller cam bearings are i...

These intake manifold modifications will help but, not totally cure the issue.
