![]() Your combo is very, very similar to mine.
I run a 347 but with TF Street Heats and 10.5:1 compression. When I switched from a GT40 upper to a Down's Ford Box upper my ET went from a 11.70 to a 11.59. I changed nothing else, so I recommend a Box upper. Well, I might recommend a gear change, I also am running 4.10. A big difference from your 3.27. |
