4150 Super Victor 370 update Just wanted to give opnion on my conversion and maybe open up some discussion.
Old setup:11.6:1 compression/370 cubic inches/TFS225's/Fast 102/102 Big cam.
This setup was fairly strong netting 11.0 at 123. Ran good, took nitrous well and sounded preety mean through the 4" cat-back. BUT... I wanted something different and new.
New setup: Uncharted terrority to me, I bailed off in a Single plane 4150 setup with custom Tick cam. Also had the heads cleaned up and a valve job done. The cutting of the cowl almost made me cry LOL but I pulled the AC out a few years back so I thought "No turning back now"
The new setup needs tuning, and I"m waiting on VFN to finish my c-5 style cowl hood. I can tell you this:THE 4150 RESPONSIVENESS IS ABSOLUTLEY RETARDED!!! I took her "around the block" yesterday and stuck it on concrete from about 15mph. Results? The shift light and 7400 revlimiter both came on instantly blistering the 325's! With the old set up it used to move out and at the top of first it would haze the tires.(th350) There will be sceptics I'm sure, but the fun factor of the 4150 over the conventional style intake/TB is a win in itself for me. The airfilter is just to keep **** from getting in the tb while the car sits. Its Way to small I know. Gotta find a better setup for the street.

Great thread OP. I'm glad the setup is working out well for you. I love seeing something different and unconventional. If you don't mind me asking, what was the price difference in going to this intake setup over what you had prior? Are you going to tune the carb yourself? I've heard they are much easier to tune than an EFI setup. What are you thoughts? I'd also love to know the specs of the cam? Sounds mean as hell.

It is actually a 4150 Accufab throttlebody and and its still injected with the stock PCM. 48 lb an hour injectors. Geoff at EPS will be tuning it here soon. I had a USED EPS carb cam that was going in the motor but upon inspecting (when putting it in) found a bend in the cam. 
NOTE: USED CAMSHAFT. NOT FROM EPS. Got it from some jackass on Texas craigslist. Went with Tick for a quick turnaround and couldnt be happier. I feel Geoff and Martin are prob two of the best in camshaft design!

10 4. Thats the only way to run these setups with out killing the airflow to the throttlebody.....unless your forced induction. 2 main rules I've read and researched on the single plane/4150 throttle body. You must have a cam ground for the shorter runners, and don't use an elbow if at all possible. The gains will show here soon when Geoff tunes it and I get to the track.

So running the filter is OK for street driving? Do you think an induction setup like this would be beneficial on a stock cube LS1 (given the cam is spec'd for the given intake/TB), or is this best suited for bigger cubes? It's funny you posted this thread because last week, I was doing a lot of research on different intake/TB setups, like the Vic Jr, ProFlow and Holley.
With what all you had to buy, is the cost about the same as buying a FAST/TB or is it more?

True the cam is going to be one key factor in the gain game. Not to contradict my last statement but I think its about an effecient combo, putting all the right ingredients together whether it be single plane or not. I do feel that out of all my years building and playing with LS1's, this singleplane 4150 combo has been the most responsive combo I've ever put together. LOL and it's not even tuned yet!

You hit the nail on the head SILVERBIRD97 when you said that the cam is the key. I think many people look down on a single plane intake because they feel there will be a loss of low end torque/throttle response, which is correct if you have the wrong cam for that particular application. I feel that if you have someone spec out the right cam, you won't have that issue at all. With an intake like that, you can't just grab some off the shelf cam and expect it to work perfectly and not compromise low end torque. I am going to be very interested to see how much you pick up over the FAST setup. Since you had Martin custom spec out the cam for you, you know it's going to perform perfectly. That guy knows his **** when it comes to cams.

As many other members here probably understand, the economy grately affects my progression on the hot rod. I hope to get a base tune in the car Friday and watch the wideband until money allows me to dyno tune. Which ever comes first,dyno or track time I will post it up, but may take a little while. Please be patient and as the progress comes I will post.

Went to EPS Friday and dialed it in and strapped it down. Made 450 @ the tire in 90 degree heat! The real gain was from 6000 on up! At 6500 verses the old set up, it made 30 more rwhp!!! Pulled it to 7200 and never fell off! Also we had no loss of power anywhere in the powerband! Please take into consideration this is through a th400 and a 4200 stall and a 12 bolt.
I can't wait to go to the track with it! But..... I've got an issue. The last pull the valvetrain was noisy as hell coming back down. Pulled apart last night and found a lifter plunger either collapsed and stuck, or wiped a lobe on the cam. I hope its lifter.....
