Victor Jr EFI Intake

redliner said
Not in an A body, but I need some opinions. '86 Ramcharger, 4.10 gears, 727 trans w/stock converter.

My old setup, '90 360, 9.3:1 comp, cleaned up 208 heads w/stock 1.88/1.60 valves, 192/203, .459/.471 lift roller, 114LSA, RPM Airgap and headers, fed by a swapped in stock '89 2bbl TBI system.

New setup, same short block, Eddy RPM heads, 10.25 comp, a still mild 226/230, .530 lift roller, 110 LSA, Eddy MPFI which uses the Vic Jr intake, same headers. I degreed the cam etc.

This thing is a soggy turd below 2500. Wooding the throttle won't even kick rocks in the dirt from a dead stop. I spent some phone time with Edelbrock tech getting the tune pretty close. New base map and some tweaks. Runs fine, just a turd off idle.

My old setup pulled better with the 30+ year old untunable TBI. A lot better. Spent close to $6k on this thing, one would think it would at least match a 30 year old system that was never known for it's power making abilities.

The rpm range of the Vic Jr starts at 3500, thinking I have a port velocity issue due to the big assed intake.

Your thoughts?

I don't have any experience with the Edelbrock EFI, only megasquirt and some Holley Terminator EFI. When you say its a turd, does it stumble, or just not have any power and accelerate slowly? What's the AFR go to when you mash on it from under 2500? Do you have a a way to post a pic of the timing table. When I got mine going, I didn't know where the motor would like the timing to come in. Needless to say I was too conservative and it didn't perform like I had expected. A few keystrokes later and a few more degrees of timing at a lower RPM and it was a totally different car.

That stock converter may be too tight now also.
