good morning,
I'm looking for new headers for my '70 Nova. My old ones seems to be too small.
The front subframe is stock.
The flange has to be for ProTopline "as cast" aluminum SBC heads and the tubes should be bigger then 1 3/4".
As my new engine will have around 750-800HP the old headers with 1 3/4" tubes seems to be too small and the Dart flange will not fit.
Does anyone has experiences in that and can help?
greets and thx in advance
