Thanks. I have a center main strap also. My blown 276 with c4 I force shift out of passing gear at 5200.

my 304ci with L100 cam 1.6 valves, hit the 5500rpm a few times with no trouble...

But on a regulary basis a never go over 5k

So Running My Roadster 50 mph @2400 Rpm Is Ok? Stock Flat head (51 Engine)

Thanks for the generous endorsement of my book Ron. There have been many myths and much mis-information about Flathead performance and I tried to put the facts on the table along with explaining how and why things work the way they do.

Anyone else notice in the Ford's River Rouge plant thread video that they were running a test engine on the dyno at around 4500 rpm. Apparently Ford thought that was a good test point. That also matches up with the max scale on the factory Horsepower/Torque charts.

I was talking with a bunch of the old time dirt track racers and they all said that the great thing about the flatheads is that you couldn't blow one up! They just didn't rev. up enough to throw the rods. Of course this is not true if you have a defective part or the bearings start to seize up.

Yep, perfectly fine, it would be ok driving to the moon and back at that rpm. Add another 1500rpm and it would still not scatter parts, for the same moon and back journey. It's been said that a stock flathead can't rev high enough to kill its self, in good order this is pretty much true. They wernt the Hot Rod engine choice for years for no reason.
Its a real strong engine, I've said it before and I'll say it again, they are not made of chocolate and cheese, they be a good engine made of good stuff!
Use it and enjoy it.
Martin.

I thought torgue was king-if so 2000 rpms is the sweet spot. We have a lot of discussions about this at our Wednesday breakfasts and guys who know swear by torgue.
