SBM Edelbrock/Speedmaster Head Data
Thanks for sharing history and innovations with us. Found the Poly fascinating when I first learned about them. Only took about 50 years to acquire one, not because they couldn't be found, but was playing with 340's and a 360. Have you run in water with the 2.02 valve? The LS intake swap looks interesting...just need those angled adapter plates. Thanks for sharing the pictures and info!
