I am upgrading a 65 Mustang with a 68 302. I updated the timing chain (double roller) among many other things. After installing the new T Chain, I noticed the cam dowel pin does not reach the eccentric. I could not find another, longer dowel, so it's an opportune time to upgrade to electric fuel pump, any recommendations?? I have a new E-brock AVS 2 4 bbl carb 650cfm, dual plane manifold,..shooting for 350+ HP. any advice appreciated mucho
