# questions: injectors, chips & tpi polishing

1) I need to upgrade the injectors on my 355. The engine was already built when I bought the car so I don't know all of the exact specs but do know it's running the stock 19#ers from the original 305. Engine mods are as follows: 355, 9.5 to 1, Sportsman II heads, Crane non-roller Compucam (not sure but sounds like its about 214 @ 0.050 & .480) edelbrock intake, runners & 58mm throttlebody, msd-6AL, 1 3/4" headers, etc. I know the 58mm TB is a little overkill right now but that's what it came w/ & I plan on doing a new engine soon with a HEALTHY roller cam anyway. Should I go the 24# SVO route or 30#?
2)I'm still running the stock chip so I know I can unleash a lot of potential here! Any suggestions? I've been checking out the TPIS Level IV, is it worth the money?
3)I want to get my plenum & runners polished for the looks department. Anyone in the Baltimore, MD area or someone I can ship them to for a FAST turn-around?
Thanks for the info!
