I like t use aluminum balls. They retain their shape and are easier to measure, giving a more accurate results. I used clay for many years, but found the alum balls better and easier to use. I don't think the piston dome shape inrelation to the dome in the head is important in a street engine just get the pottom edge of the piston to head clearance down to around .040.,050, SBC is .o35.

I've heard the L-100 described as the "smiley cam". Does this mean it has a nice lopey idle, but is not a good cam for a street car?

Yes, the sound is exceptionally well liked as the sound of a flathead. Installed in a large displacement , hi compression engine and properly tuned. I can give excellent fuel economy as well as excellent power in a heavy car.. The biggest problems with most builds is improper tuning. This has been solved by both Bubba and Charley NY. Unfortunately, after spending many$$$$$$, they don't tunne them properly. The "tuning of a flathead" has ben discussed on this forun a dozen times, and it works.

Kiwi, that is a sweet sounding engine and the cars looks great also. I was thinking that would make some inspirational background music for the shop.

Hey Jack,

To confirm, you has 127,000 or 12,700 miles?

If it's 127,000, that's impressive.

A 400 Jr, for comparison. I think he could have got it to idle a little lower though.

Thanks, Ron I'm building a 296 with either 81A or EAB heads (depends on which block I use) for my '40 sedan. Would the L-100 work on the street?

Russ I have a Schneider 248 f in my roadster. Have a .325 rear end.
I am very happy with the way this cam drives. It will putt along on country roads and has a lot of power on the Highway

Yes - you have enough cubic inches to make it work well. What compression ratio are you headed toward? Mill the heads and get .040 over the pistons - makes a big difference. If you're in a light enough car (sedan might not be it) and have the right gears, could even go to a Potvin 425.

It does sound good, but it's running awful rich. The biggest problem I have with 97 carbs is tuning them for economy. The best carb I;ve found is the 500 cfm Edelbrock. Richard gor 22 mpg wiyh the 276 in a 3800l 53 Ht. AF i n cruise was 15.5, 13 at WOT and an L-100 cam
