Looks like a relatively stock cam with a little more duration. You may not feel much improvement of the engine so OEM injectors should work just fine.

Re: 1988 IROC 5.7 New Cam
I run the 8800 with 1.6 rockers. It feels exactly like stock. You do not need to worry about injectors.
Wish I had invested in a two piece timing cover as I'd like to try the 8801 but there's now way in h3ll I'll spend another Sunday under the car getting the timing cover to seal up properly to the oil pan. It's too much work imho changing cams

HA! I use a Milodon gear drive timing system. Taking off a stock cover to change a cam is easy.

Btw, doesn't the knock sensor complain on your gear drive?
