I am going to install a vacumn can for the trip and worry about the motor later,the 55 that its in is going to get a 292 Y block built for it next year and I will be putting the 351 in my 65 custom 500. When the 351 comes out and on the stand I will change the cam,intake and heads and hopfully wake it up a little. I would like to fix it before the trip but dont want to tear open the motor so soon before leaving so its best left as it is.
