Assuming you’re running a flat tappet cam.....
You’ll have way more open load than I’d want in a bracket motor(along with very questionable cam/lifter life).

If it’s a roller cam, you’d have less than I’d want.

The specs are listed at [email protected], with a rate of 571lbs/in.

For either a SFT or roller...... there would be better options imo.
