Default Just ordered a MS4

Well I took the plunge and ordered the Magic Stick V4 cam dual springs Ti retainers and molly push rods from TSP. I must say they were very helpful guys to deal with.

Looking forward to bolting it in along with a Victor Jr manifold and 4bbl throttle body.

What's the consensus with injector sizes with this cam for a cam only motor? I've just got the stock LS6 28.8 pound injectors.

I decided to keep the blower manifold for another project and sell the Eaton M112. I think the simplicity of a N/A setup will be good and it'll make more than enough power for a light weight fiberglass AC Cobra.

Cheers

Michael

Cam only your injectors should be adequate.

Thanks,

Does anyone up the fuel pressure to get a bit more out of them? I've got a Bosch 044 pump and Sard adjustable reg.

Cheers

you can set your rail psi at 62psi so when you go WOT it will go down to 58psi which is where you want it at.
You could be maxing out 28lbs injectors, 30SVOs (35.54 @58psi) are a better choice.
