Not exactly mustang related but I hope you can help. I'm wondering if a 2500 stall converter would be enough for a f303. It would be in a 94 lighting with a10:1 351 mass add converted running a mustang a9p computer. It currently has a e303 with a 1800 stall and I have the tranny out replacing the converter with a 2500 stall and new front pump. I have the f can brand new and always though the e was on the very small side in the 351. I think the f would work better with the heavily ported Windsor Jr. Heads and the gt40 upper and lower then the e would. Thanks for any input. Please no flames about the alphabet cams it would be a free swap for me.
