What pitch should I use
Hi my names Matt and Iam new to this site, just recently bought a 93 barchette and it has a 4.3.
The motor needed some work so we tore it apart and in putting it back to gatter we decided to port the heads. I dont no if it helped out but I took it out with a 19 pitch and its runing 47mph on the gps at 5,800. Was thinking of putting a 23 pitch on it to get it down to 4,800, what do u guys think. |

All that said there is 1 member here who says he runs a 23" pitch on his 18' Barchetta with the 4.3L and gets good performance. I dunno how he does it but....I'm taking him at his word. |
