I have a 92 RS L03, i want to install my freshly built 327 into it. I read in the tech. section that if you follow the steps they list, you don't need the ECM anymore??? Is this true??? I was worried about putting the 440 h.p. engine in it because I thought it would be too difficult with all the wiring and computers, but if I follow the directions, (carb,intake,feul pump, ect.) I can just take out the ECM and be rid of it???
Also, I thought my trans. is computer controlled???(auto 4L60) if it's not then my block should bolt up with out any problems right??? thanks for the help guys.

 

I'll offer some advice that doesn't answer your questions, and then take a stab at your questions.

Don't throw away or hack up any of the factory parts that make your car legal. You never know when the EPA will come to your town, or where the car will end up. It's worth the box or two in the attic to keep that stuff.

Otherwise, what you've heard sounds good, except that the computer controls the locking of the torque convertor clutch. If you want that function available, you'll either have to hook up a manual switch (see tech article), or get an aftermarket system that will do it like the computer used to. The tranny will bolt up to the block. You didn't say what heads you used, but 327 factory heads will not have the accessory mounting holes your original engine had. But, if you really are making 440 hp, you probably don't have factory 327 heads.

You shouldn't have to replace the fuel pump, just regulate it down to 5-7 psi.

I would have to agree keep that stuff around in the event that you will need it or if you sale the car some one may want it. I was thinking of a 327 myself but I have not heard of a 327 with that kind of horsepower I have heard of them having 350 HP stock but would you have to have everything forged to get that kind of power from a 327? What are the stats of your engine?

 

I used a 350 block, put in a forged cast large journal 327 crank. then my trickflow rods, and JE pistons. Then I have trick flow heads, dual tunnel ram and 2 850 race deamon carbs. The engine dynoed at 441 h.p., 534 lbs. of torque, I have recently added roller rockers, and a three angle valve job, don't know stats now.

 

Whew, that sounds really over-carb'd. I know 500 cid big blocks making more power than that on Victor Jr's w/single 850 carb. I doubt that will be very streetable - no power below 5 grand. You should easily get by with twin 450's if you really want to keep that manifold, but it will still severely limit low-end power. A single 750 on a single plane manifold would do much better for both driveability and power.

But, then, you didn't ask about that. Just my opinion. I love 327's, wouldn't mind having one. It's not hard to over-do it, though.

 

This engine is for show only, and the ocassional 1/4 mile runs at Route 66 raceway,
and Indianapolis Raceway park. I have a show winner camaro, and thought with this fully chromed engine, I would be unstoppable.
What do you think????

 

I think I agree with the "kid." For pure power you don't need all you got. But the tech advice he gave you about eliminating the computer is rock-solid, as is the advice about down-sizing the dual carbs. But I'm just old enough to know what a full-house on a tunnel ram does for the SOUL- very hard to resist the temptation.

Please keep in mind that the ECM controlls the stock distirbutor, too. Since you have gone WAY overboard on the carb setup you'll also want to go with a mechanical advance distributor (Whatever traditional distributor will fit behind the tunnel ram manifold). Ths stock computer controlled distirbutor will still WORK but the advance curve the ECM gives it will be weak since without the computer controlled carb/TBI/ and whatever other stuff you tore off the thing since it was stock the ECM will be running in "limp home" mode. And I can think of no better way to suck 100HP out of a 400HP engine than give it a lousy spark advance curve.

I'm sorry, I forgot the MSD 6AL ignition set up, I have all the bases covered, and I really appreciate all of your help. 327 here I come!!!!
