66 Impala Convert LS2 Conversion
While I can't say for sure on the Holley covers but stock LS valve covers have restrictions in them that might be around .100". You would never know unless you take the baffles out like I did. The Holley's may have this also but you would have to call, sit on hold for several hours and hope you got someone that knows what they are talking about

The Holley covers have no restrictor holes ..........Tubing I.D. straight thru.....

I think you need a system that has some sort of pressure relief. The stock pump modules have this which is why they work well. Carl can tell you for sure or if there is a work around.
Second Issue........After installing the Hydro Boost........I had a little minor issue of while turning, I would get a little intermittent loss of power assist.......I did some research and was told there was a slight amount of air in the system........I noticed that in the reservoir there was some turbulence from the return line in the tank with possible aeration..........I checked online and found that Concept One had a tank they specifically built for these applications that controlled the flow and softened the flow entering the tank to eliminate this problem......So.....
I took the car to Frame-Up Wheelworks and they went thru and installed everything as well as neatened up my mess of wires around the battery........after getting the car back all I can say is....getting everything close and working is O.K..........But......Putting the Bow on the Package and Fine tuning everything makes driving the car nothing but sheer enjoyment......Damm!!.......This Beater is Fun !!!




I hear you on the fine tuning. Shows like Overhauling make it seem like you can just bolt a bunch of expensive parts together and the car will drive and handle great. That's just not the case in the real world.

So....After finishing Gary's 65 and getting the exhaust completed with DynoMax Super Turbo Mufflers, an "X" pipe and tail pipes that exit behind the rear tires........His car sounded perfect........So.....I decided with last Winters mods to the Impala I needed to free up the Exhaust system.........It's going to the Exhaust shop on Monday for this "Correction" ....LOL.....I also bought a set of Headers off eBay that are supposed to fit........We will see........

I had the exhaust dumping out just after the rear tires (headers, X pipe, and Magnaflow XL mufflers) but the drone was HORRIBLE. At certain RPMs it would drown out the radio and good luck trying to talk to anyone in the passenger seat. My solution (that I am still working on) is to extend the exhaust to the bumper, and I am also adding 2 Vibrant 1792 resonators right before the tips to lower the volume a bit and help with the rasp. I will report back on how it works out.

Done on a turbo Porsche for me. No muffling and I can have a normal conversation inside at cruise vs a screaming migraine before. No mufflers on this car either
