It took awhile but it sounds great and after some tuning got 420HP
Dyno sheet was not the final pull but you get the idea.
Olds 350..

That's 420 lb-ft of torque. HP is last column at right.

Dang little torque monster. 🤣

Yes but after some more tuning and we were able to get 420 hp . It’s not on that paper printout.
The torque is plenty also for my plans of just cruising around.
