360 CI/ 380 HP Really?

10* initial isnt enough for the motor. I would shoot for 15 to 18*
The Dougs headers will be fine.

What converter and flex plate do you have now ? The magnum motors use a different balance then earlier 360 LA motors.

I have a B&M Holeshot converter in the car now. It was in the car when I bought it. it is a neutral balanced converter and I bought the correct B&M magnum flex plate for the crate engine. The notch or cutout is in a differnt place and is a different size between the magnum and LA flex plates
