zomg.. i see a scratch on it
im joking, i know i shouldnt
looks good though man, how much of an improvement are you expecting
mike that sounds like something you would be into, at least with a skirt on you would have lots of airflow down there

Well when Bret and I talked he said 20 ish HP over what I had, here recently in Engine Masters magazine they did the not ported/ported supervic back to back on an engine dyno and it was 18 hp. The one in the test looked similar to what Bret did to mine.
heres dyno proof for a ported victors

yep a good ported intake is worth that..ive seen some with the spacers blended so good also you would think it was all one port plenum and not a spacer sitting on top of a plenum

Mine has the carb opening enlarged like discussed in that thread. Straighter line of sight, better air distribution, and increased plenum volume. I actually have the sheetmetal elbow in FFB's picture of his old setup, and had to port match it to my supervic's enlarged opening. Nothing a permanent marker, pencil, construction paper, and a dremel couldn't fix.
I will need to spin the hell out of my 383 to see the benefit, but that won't be a problem on the LSX pcm and overbuilt bottom end.
Still eagerly awaiting results from all of this FFB. Very curious how it picks up over the stock supervic/elbow setup...
Yep, on a big engine or one that sees high rpm you can get some decent gains porting a supervic. Not your everyday H/C build, but when you start getting nasty then there are gains to be had.

I also have to install a J&S knock alert, cut and re-do the cowl for the carb hat, get my lifters rebuilt(sending them off today).
So its gonna be a little while but I will keep you guys updated.
