You've actually seen this on the dyno with the same shortblock? With the only difference being chamber size. ? Is the power difference from compression increase or more airflow ?

Excellent video. I can’t wait to see more. In the future I’d love to see the different top end kits you sell, and the performance differences. And some intake manifold comparisons between the dual and single planes.

Not a 3v head
