Featured Technical ***August 2025 Banger Meet Thread - Yes, Already***

I’ve got both a Best 509 and 573 head gasket. The 573 was sent with my D4B Head by Dan Price(Dan 4Banger). The only difference I can see is that the 573 has the steam holes. The fire rings appear identical. I would think the 537 could be used with no problem caused by the steam holes not being used.
Oddly enough the head does not have steam holes. The photos show the 537 overlaying the 509.

 

Hello Banger Guys! Long time no speak. I hope everyone here is well and is having a great summer. I have been missing the HAMB and am going to try to log in more often. Nothing new going on in Cheyoming. My coupe has been running and the new grandbaby loves going for a spin in it.

 

@Binger Welcome Back and congratulations on the grandbaby....
just thinking about you...headed to Badger Raceway for the Dirt Drags and will be going thru Cheyanne on the 29th....I'll give you a shout out

 

I saw that other thread. We had a great time when we went the last 2 years. The Black Hills are a lot of fun too. I work the 29th but Depending on when you come through I can make arrangements to be available. Are you planning on coming back through Cheyenne? I have also been considering going to the drags but am not sure.

 

Quick question if I may.
I’m putting together a motor for a friend that has the Roof 101 head.
We’re looking at ignition timing. Wonder if anyone has any timing figures for that head.
Reason for asking, this one is liking 45° of advance.
Thanks. Pete.

 

I know Shaun, at FSI, and I had a discussion about timing on the OHV conversions.
My Miller OHV like at least 40 degrees of initial advance
I also have talked with Steve Serr and his head likes crazy amounts of advance too
this said...I have just been timing mine, using the butt dyno and what I call 'calibration hill' which is a 4% climb to 7100' elevation....and don't ever but a timing light on it....I have many many miles and no problems as a result of such advanced timing....
compression ratios are under 6.5:1 for another consideration
and I probably shouldn't state it this way....don't be retarded....
let us know

 

That's the same number that came up a couple days ago when talking about other OHV Bangers and where they made their best power.

 

I have been hearing that this is a good time...Ken Long and his boy Hudson will be there maybe later Saturday..We will be coming back thru Cheyenne on Monday, gotta take one of the boys back to Ft. Collins, CO.

 

Thank you both for the replies.
The motor is supercharged too, which complicates things somewhat. But we’re still getting max power at 44° even with boost. Crazy amount of advance.
With the static cr and boost we’re around 11.7:1 cr.

Thank you, we know we’re in the ball park now.

 

This is the engine on the dyno.
This is the engine before we replaced the distributor with an ecu.


It’s a B block with a Burtz 5 bearing crank fitted.


Thanks again.
Pete.
