Hey Hogg, been reading and learning from you for years regarding the L31. Great stuff you have put out there over the years. I have a question for you. I have a '96 RC/SB stepside, with 4L60e and 3.42 gears. I've upgraded to the 0411 pcm, and have purchased a new 12530283 long block, and plan to use Thorley long tube tri-y headers (1-5/8").
I'm wanting to upgrade the camshaft, as this will be my playtoy. I'm liking the SP350/367 cam you seem to be promoting these days over the LT4 hotcam. My questions are: 1) do I need to upgrade the springs/retainers/locks? 2) Should I use roller rockers? 3)If so, what is best rocker ratio (would prefer to NOT remove heads from block)? 4)Do you still recommend upgrade to S10 TC with this cam ? 5) Do you think adding the Ramjet intake will help greatly ? Lastly, I am also planning to upgrade to coil on plug ingition during this cam swap (EFI connection). Thanks in advance for all of your help on this. Mike
