Just got done putting a 224R on a 112LSA from texas speed.

We got it done in a day had the new cam in by 1pm yesterday started at around 8ish. Went smooth even with the under drive pulley. Not a single problem On my 99 corvette.

Takes some feathering to get it to idle but once its warm its fine. Getting it tuned next week. I was amazed how easy this was to do. Still waiting on my new coolant plugs from the dealer or the ls6 intake would have went on this weekend as well. The sound is amazing cannot wait til i get it tuned so i can take this baby WOT

 

what did you use to hold up the lifters, and compress the springs?

 

Im guessing you used a "screw type" puller for the underdrive pulley? I was interested because I will doing a cam swap here shortly and would like all the advice I can get.
