i think grumpy does you might want to get in contact with him

 

Thank Pablo.

 

Used a Comp Cam 270 for years with a 747 sytem. with 224 @ .050 took some doing but was great was done.
The VE tables look a little weird, but the car was fine to drive

 

What is a 747 system? Could you possibly explain your problems and adjustments with that cam/MAP set-up, Grumpy?

go here www.Diy-efi.org

go to the gmecm section
and then to articles

read Tuning Tips and read Programming 101 both written by grumpy on the basics of getting a given setup to work

 

Outstanding, thank you Pablo.

 

Thanks alot for the feed back Grumpy. I found a roller cam on Ebay 230/236 @.050 110 LSA. I wondered if I could run it. Thanks.

Only since it's a big cube engine.
that would really be a stretch to do on a 350.
But your outta injectors.
Probably gonna need to find a set of the early BBC ones.
