Greetings to all...
Last summer, I decided to swap orig. Comp Cams 288 Extreme Energy for a Comp Cams 11-445-8 Marine 270 @ 112 lobe sep., PLUS, swap out 3310-1 for EZ EFI, Gen.1., the whole object being to bring this engine’s component system closer to the actual Flip-Flop in pattern use that has evolved to a cross-country road vehicle with the odd Club Track day thrown in, rather than the orig. plan for a predominantly track oriented car that could be driven to the track. Goals: Improved fuel economy, better drivability, cooler running, reduced emissions, without giving up all the torque fun of of a C-4, 523 CID/ZF-6.
The orig. intake still on is an Edelbrock Air Gap RPM, Oval Port and they are 6145 Edelbrock Marine heads.
A year down the road shows this swap is less than ideal because apparently, according to FAST Forums, Throttle bodied EFI’s do not “Like” dual plane intakes. My engine exhibits the typical 4 fat, 4 lean plug
pattern that is common for a dual plane.
Apparently, recommended RPM ranges for single plane’s are irrelevant for the EZ EFI, all the posts on FAST’s support forums indicate a Victor Jr. or similar will enhance EZ EFI from idle up.
Was thinking Torker.2, but Fuel Reversion may be an issue with low rise.
Any insights?
