Turbo 383 in a A-body Barracuda

Hell, Now I am lost! I am going to look at what spring is in the box.

I left the tallest inner spring in I think. Seem to be the easiest one to compress!


So, you left the lightest spring in??
This difference with size(height, circumfrence, thickness??) is conflicting..

The small spring was a ***** to compress in the housing. My vise didn't open enuff! I should have took pics.

I just finished my B!tch Duties so I will go out to the shop later and check it out. I have a vacuum pump and tested the BOV. Started to open at 12..

Where are you running the hoses for the wastegate and bov? From the way it looks this BMC needs reference from the compressor housing then into the wastegate. I guess It will need to be installed under the hood near the wastegate. This will be pressurized so I think the length of hose is limited. They have a cable kit but it too is pricey. I wonder if I can run a set of hardlines into the cabin under the dash and back to locate the BMC.


Looks like the BOV is referenced from the intake below the carb so under boost it will pressurize the diaphram and hold the wastegate shut. BOV should blow at 12psi if it opens at 12 vacuum when off throttle? I guess I can tee from intake to reference boost for the fuel pump controller and the MSD Boost retard and the Autometer Boost gauge?

I think thats right??

So much to learn!! Gonna knock the cobwebs out a bit! LoL!

Yes you are correct I left the the middle spring in. The one with the thinest wire on the coil.

You just confused the crap out of me! I tried to follow your hose diagram in my head and got lost! haaaaa :toothy10:

I haven't got there yet on the vacuum and boost lines.
I did get the extreme velocity hat and I can't run it straight out the front of the engine because the bottom of it hits the top of the front carb bowl! I will need to re route the intake tract.

MadDart!!

Have you chose your cam yet??

I got mine but was said to be a possible issue. The Turbo crower and Isky cams have the same lobe seperation of 114, mine is a 112. The turbo cams have a decent duration of 280 something, mine is 287. Their lift is what I don't understand at .420-.470?? The Blower cams look better than the Turbo cams do! My lift is .540 tho?? I have decided to ditch the Single plane Torker2 for a Performer RPM Dual plane since the rpm range on the Performer is 1500-6500 ..

Any comments?? 11-29-2010 06:18 PM

Brian at IMM Engines is ordering the cam. It will be a Solid Roller. Duration is 240*@50 ground on a 111* ICL Lift is .638 if I remember correctly. I will be using an RPM PERFORMER and maybe later switching out to a Victor Junior Intake manifold. With the Air/Water intercoolers, heat exchanger with Ice Box in the trunk and the Meth Injection. The intake charge should be fairly cool and a AIR GAP style manifold will not necessarily be needed.
