I got a set of Delphi/Lucas 42# injectors from Thunder Racing and they are great. No problems tuning for them, idle is nice and I get 28 mpg all highway. I am at 58% duty cycle at 6400 Rpms, plenty of room for growth, for that 4" stroke...

Bolt ons, cam and heads will be close to getting by on stock 1998 injectors. You could run it on a dyno with a wideband and see the a/f ratio. If you want to change and do a new tune, I'm a believer in the 42lb svo's. Idle great, easy to tune and will give you a lot of room to add hp later.
