The E clones on my 409 have only seen dyno time so I can't say how the transition circuits are yet-maybe in the next year if I find a paint shop that won't put it in "paint jail". My 470/409 liked the 600s over the 750s. The Edelbrock intake flows way better than even the hi perf aluminum 409 dual quad and single quad intakes. I never flowed the Edelbrock dual quad Pontiac intake when I had one. M/T Pontiac cross ram does not flow as good as a single plane intake, but looks cooler!
