Start Up fuel Question

[2000xjclassic]

Planning on finishing up and installing my 4.5 +.020 over bore stroker in a 2000 xj on the next few weeks.
Quick run down of specs are:
Comp Cams CL68-232-4
Mopar Perf. valve springs, retainers, locks, head gasket.
93 Block and head.
late style intake, banks torque tube header.
4.0 rods and KB944 pistons.

I have a APEXi SAFC 2 and will most likely run ford mustang injectors. My question is when I start it, will I be ok to start and run break in(20 minutes at 2K RPM + first 30 minutes + first 300 miles) on the stock injectors, computer and tune? Or should I go ahead and buy the larger injectors and let it run rich until I get an A/F meter on it and tune it?

Thanks in advance.

Chris


EDIT:I guess I am trying to ask which is more of a problem here, detonation and the problems from running lean or cylinder wash and the problems from running rich.

Cam break in will be no problem. I would be cautions for the road time though as it will be running lean after about 3000 RPM with the stock injectors.

I also run the SAFC II

silver what do you think of that safc II? i still can't decide what kinda fuel management i'm gonna use for my stroker and i get the block back next week

[SilverXJ]

Its simple and easy to use and works well for AFRs. It doesn't have all the data points, timing nor some features that others have though.

[shawnxj]

wonder if it'll work with a renix computer

[SilverXJ]

It modifies the map signal to the PCM I see no reason why it wouldn't
