Hello and greetings fellow loyal GM Enthusiasts. My name is Chris and i've ran myself into a quite interesting situation here. I have built myself a rather radical LT4 383 in my 95 TA M6. I am having dilemma w/ a Arizona Speed & Marine Monoblade TB on my motor. As you may know the factory TB has a provision on the passenger side for a what i call, a fake PCV valve, and a smaller provision for the EVAP canister purge solenoid. Well I was wondering what the fellow monoblade LTx owners did to solve those two problems. I have a set of corvette fuel rail covers on top of a set of LT4/Corvette valve covers. What did everybody do to the EVAP line from the purge solenoid. Did you just tie it into the front of the throttle body since its best to have the fuel vapors evenly distributed rather than on a vacuum fitting on one side of the intake? Plus, what kind of breather did you use to put in the passenger side of the valve cover? I'm thinking about getting a stiff piece of rubber hose w/ a 90 degree and running it up on top of the fuel rail where it'll attach to one of those mini K&N crankcase filters. Thanks in advance for your much needed help! Here's a pic of my engine bay to help you understand what i'm talking about. http://www.fquick.com/garages/viewga...wimg&id=212352

anybody have any opinions on this?

 

my lt1 intake has an oem tapped hole on the front of the manifold,just below the t-body...my evap hose is hooked in there with a 90* ftg.

 

On 95+ F-bodies that hole is occupied by a fitting and a aluminum line runs to the drivers side of the intake to the real PCV valve. However on the 93 & 94's the vacuum line for the PCV valve is close to 2" away and the hose does a 180 and plug into the PCV. I'll check into that a bit. I might have to hook it up there and just run the PCV like the older 93's and 94's. Thanks for the reply!

 

I have an AS&M monoblade on my L98. I just finished the machining for the PCV valve and the EVAP line in the body of the monoblade. I followed the routing of the stock unit. Then threaded and installed the proper barbed fittings for the hoses.

 

Not to sound like a total bum but can you post up a pic of it? I wish to see if the Monoblades designed for the L98 are somewhat the same as the LT1's. I've given that some serious thought, but there isn't much room on the side where the TPS is. Thanks for the reply!!

 

I ordered the TPI throttle body for my L98. AS&M sent me one for the LT1 as that is all they had and said it would work. I had to make up adaptor cables for the TPS switch and the IAC. So I'm running the LT1 monoblade on my TPI.

I see! You've been more than enough help, so i'd hate to ask this. Got any pictures of where you drilled the holes and installed everything? I can see the EVAP one fairly easy. Best bet there is to drill a hole on the throttle body from back to front the inside of the gasket to intake face and mill a small grove along from the hole to the top of the TB in the middle where it will distribute the fumes evenly. Just as long as you stay inside the gasket to throttle body face you'll be fine. Its just the fake PCV valve one that has me puzzled.
