Single Plane for LT4 ?
Right now I have a GMPP dual plane carbed intake for my 383 LT4. It has AFR LT4 heads, all forged internals, Holly 4150 style carb & MSD ignition, etc. I know a lot will probably say its a waste to have converted it over but its done anyways.
Now I am looking for a single plane setup. I know there is not a direct bolt on intake but heard about the Super Vic and Vic Jr.s being converted over. Is there anyone out there that will do this, like any web site info? What part number for the intake will I need? Some places I read said all have to do is drill & tap wit the right intake, this true?
Any help or ihnfo is greatly apprectiated. Wanna switch over to a single plane asap for the summer racing series coming up. Did search but couldnt find much like intake part numbers.

It's not an easy swap. Any good engine builder could do it for you though. It requires the ability to use measuring tools, accuate machining and minor fabrication skills. If you are contemplating a DIY, you shouldn't even consider it unless you can figure it out for yourself.

Contrary to some opinions its not an expensive ordeal either. I bough mine complete but most places that did it would only charge about 3-400 to do the intake.
If you are going to run converted SBC heads you can run a Vic-E off the shelf that already ahs the injector bungs in it.

The conversion can be cheap IF you don't care what it looks like. If you want something that doesn't look like a drunk handicaped guy with a drill press did it, then it's another story. Beyond that the intakes need porting. To me it seems dumb to take ported heads and put a intake on them that chokes them off, almost every single plane intake on the market other than a very few rare intakes need porting out of the box to perform.

Before that I had no idea, I thought a good single plain was great out of the box but it has more in it

I'm sure it did, we have had a few new combos go in cars this year, all very similar, 434 SBC..brodix heads, AFD intake and very little work on the intake made huge gains.

well I'm not saying I left it stock..lol. My intake was done my larry meaux. I'm just saying that they are pretty descent out of the box seeing that it outperformed my fully worked lt4. but yea..there were some nice gains to be had with working the single plane
