If the cam duration is over 250 degrees at .050 then you can't use most self learning systems and have to get a programmable system which fast and others also sell.

I think the throttle body is supposed to flow 1,000 cfm. I went with this setup because the overall height is lower than using a 4-bbl intake and carb (or throttle body EFI.) If it ever warms up around here, I hope to have it running in the next month or two. 8028679-505inj.jpg (124 downloads)

You just have to be careful with the throttle body EFI systems, as they are limited by injector size. 1958 Plymouth Suburban

I'm using the 440 Source 4.25" stroker kit for a 0.030" over 440 (505 cid.) The pistons are the 17cc dish KB ICON-839. I'm using mildly ported 84cc Stealth heads, so compression is around 10.3:1. The cam is a Comp Hydraulic Roller XR286HR-10, 236/242 duration @ 0.050, 0.581"/0.578" using 1.6:1 rocker arms. The cam seems pretty tame in my engine.
