highest C/R for 93

[DanEC]

On my stroked 428 with ported iron heads, I couldn't talk Keith Craft into going more than 9.0. Still made plenty of HP for what I was wanting - a reproduction appearance motor. The dyno operator said it loved 40 deg timing as a result. I suspect it could have tolerated another half point but that's how he wanted to build it.

Coach Mike had Keith Craft to build him a stroked 428. 601 hp with 9.0 c.r.

Lainhart had Keith to stroke his 427 to 487. It made 617 hp with 9.0 -9.5 c.r.


If you have the correct head, cam, intake set up you can make big HP with out high compression.

427Bullitt, what is your hp goal?

Coach and Lainhart drive their Cobras on the street, so 600 HP is just right

Around the 600 area, more if that's possible, but honestly as much as possible with pump gas. Are those numbers whp, or to the crank? Probably wheel horse power, but i'm just double checking.

Those would be flywheel horsepower numbers that were quoted above.

600 hp to the wheels would be up over 700hp at the flywheel. Not that it isn't possible, but money and maintenance goes up while the reliability and longevity go down.
