for the past couple weeks the car has had a stumble/miss at high rpm (4500-5800) only at WOT it is pretty consistent and has happened more than half of the time i go into that rpm range.I believe it is the injectors as I've replaced most of the ignition with the exclusion of the opti.

My question being that i plan to install a small cam and mild heads this winter(probably LE1 with his 218/224 cam) will injectors with stock flow(its a 93) be enough for this set up or should i be looking for something bigger? 30's maybe?

thanks for your time, Dan

 

Properly set up, and with the correct supporting mods, that should be over 400HP at the flywheel. You need 28's for 400HP. I'd think a set of 32's would allow a bit of room for better than 400HP results, and a little bit of future growth.
