Went to the track Friday. What should I try next?

[GTX JOHN]

Try shifting at 6500? ( which still seems low, but I don't know the limits of those intakes)

The factory cross ram flattens out about 6800. It needs more interconnection
area. They aftermarket replacement for the originals run 7500 fine.

Does that still apply to 80 ci bigger than stock though?

Yes it is a matter of how much Air Flow the engines need to support
a given HP level (Think Air Compressor).
Our B/SA Stock 426 Made a fair bit more HP as it ran close to 130 MPH. @
3690Lbs. The Super Stock SS/DA Max wedge made considerably more.
The intake manifold was the real problem rather than a well prepared Max
Wedge Head.

The is a fix to the interconnection problem but it is a LOT of Work to do undetectably!
I better not elaborate any further.
