340 dyno video from Brand Racing Engines

[Bobzilla]

Here is a Brand Racing Engines video showing a nice little small block Mopar doing dyno pulls. Engine specs are near the end of the video.

Cool video! That's some good numbers out of that combination. The builder says 12:1 with 112 octane, Mahle custom pistons, and Crower 6.25 rods. Someone needs to start making some motor plates or (even maybe even a fabricated timing cover!) like that water outlet adapter... Be a nice raffle win!

That guy is a one man shop.

He puts out videos worth watching.

why only 30*? thought he would have tried the magical 36* for SBM

I watched it but I didn’t stop it on the graphs too see how much more timing killed peak torque.

I know one comparison graph showed a big gain up top but it took a pretty good hit around peak torque.

I have found 34° to be the number personally

What’s the chamber like on a W2? No experience with them. They like 36 degs?

all depends. My 436” W2 liked 32*. My current 355” W2 likes 37*.

Compression similar? That is a significant difference!

Just curious, why go from 436 to 355? more rpm?

436” is 13:1
355” is 11.6

I shifted the 436” at 7200 rpm, 355” gets shifted at 7300 rpm. I sold the engine and put the car back to street and sold the car.

I had a 3.46” crank with BME aluminum rods with pistons sitting on the shelf so I put them in a 340 block so that’s why I went with smaller cubic inch. It’s what I had at the time

Ah k, was just curious if it was a performance choice for some reason

The reason I went with a bigger stoker is the car was 3900 lbs.

Did i miss where he mentioned what heads?
Trophies he made for the car show are amazing!
