My car has a single plane 2925 Eldebrock Super Victor converted to EFI, with a hand fabricated sheetmetal upper plenmum/TB adpater. I cut the opening on it for a mono blade from the start, but wanted to see what difference there is between a 58mm and mono blade on a motor like mine, for various reasons.

The AS&M Mono Blade is well known for driveability problems and if I could make my HP goals without dealing with them, I wanted to do so.

I only port matched the Eldebrock 2925 lower to the cyl heads, otherwise it is OTB port wise. The 2925 was a brand new desgin when I started this project and no one knew that they had a massive air speed problem in the plenmum until I was well on my way... The upper radius entry to the intake runner from the plenmum needs massive amounts of work to run properly on a big motor. My sheetmetal plenmum/TB adapter seems to only be making this air speed problem worse as the motor orginally lost a crap load of HP from the engine dyno (dyno'd with a carb) to the chassis dyno.

Once I get a decent day to work on the car I'm going to do a little more testing with the new TB before I pull the intake off and have the plenmum enlarged and short side radius' re worked.
