I’ve seen “new technology” and I’m less than impressed. That includes the complicated Coyote Ford pile of ****, the weak block of the LS and the highly inefficient hemi head.
I’ve said it before but it bears repeating. I’m a life long N/A guy. None of the above is spectacular without some power adder. I’m following a turbo build here on FABO. Ritter block (far FAR a better than any of the OE blocks above) and I forget the heads. Let’s see what that does.
Also, airflow isn’t the end all of making power.
