Amazing how it runs with no crank

On the build sheet, picture 27, it said Eagle 4340 but that was funny how it wasn't in the written part.

They didn't state the head flow but considering the build what's a common Stage 2 ported flow?

Considering TA blocks are now $9k without machining this might hit a nice number.

I just went through all of it
There was 2 motors there in the pics.
I wouldn't worry about the head flow
It's the crank
The 224 cam can't full take advantage of a stage 2 head.
They flow a ton of air.

In your experience how much can one of those crankshafts handle?

Depends on the tuner,builder,etc.
I've seen with a great builder and a Great tune-up hard parts can handle more that they are advertised or what some experts think they should.
This build reflects a specific power strategy to me
The cam choice and crankshaft tell me power window goal range of 1000/1200hp but the massive stage 2 heads and aluminum block point to much higher hp interests.
The race motor to the right on the ad shows a much more aggressive goal approach.
I could wrong but based on the parts that's what it tells me
Unless the owner just wanted that stuff lol

nice motor for a BMS crank!

nice motor for a BMS crank!

BMS had several different crank options. 4140 and 4340. Key is know what you have and check it. BMS has casting marks that can help you with identifying what the material composition is.

Does this stamping mean these heads are from 1992?
