i dont think anyone has answered the question- What years did roller cams come in 351's? is it just the older lightning motors? i want to know too!

i believe it was 88 when they came in the trucks and into the police CV. i did a 90 F250 and it had a roller cam in it.

as for thicker blocks, who cares unless your are going to build some serious power, then i would get the SVO block. if you are planning to race it and spray it then spend the extra money and get the SVO block. just my opinion.
