Well, it finally happened. I have decided to get more power and increase the reliability of my tired 305. Turns out that i'll be running into the green stuff (not the shrubbery) in several months , and have started looking at the GM Goodwrench 350. Anybody know anything about these, will it work with my 84 5-speed transmission? What mods should i do while the engine is out of the car?

--Steve S-- 84 Trans Am 305 HO 5 speed, completely stock will soup up when i get some $$$$$$$$$$

 

the zz4 is a very popular engine to swap into a third gen. your t5 will fit and work just fine.

Hey I just swapped a 327 from a 65 vette into mine. It wasn't extremely hard to do. With a little planning it would have gone in much easier. Since yours is set up for an 8 cyclinder you can put in any chevy v-8 without many problems. If its carb. than its best to remove the computer and its harnesses. The wires you will need to run the motor and lights and accessorys will still be there since they are not connected to the computer. The only ones you will need to put on a switch is the fuel pump if its an electric on and your fan, again if its electric. I did this and its not too hard. Now if you put a fuel injected engine you will need the computer and harnesses for that particular engine. In any case you will need to take that computer out unless you reuse that 305 and bore it out maybe. Also with any chevy v-8 no matter what size or year from 1957 your bell housing and tranny will bolt up to it. They all have the same bolt pattern. I would suggest the 327 I am very happy with mine. It has more power than most 350's and winds up faster do to the shorter stroke. Less gas used up too. I'd also recommend you change your motor mounts while the engine is out

 

How do you remove the computer from the car? is it as easy as you make it sound? how would i go about running the pump and fans then? just put them on a relay for the ignition power? thanks!

Yeah its not too hard to pull the computer. You will need a wiring diagram first to find which wires you need to cut from the harness (Fuel, fan maybe defogger and reverse lights) Those were the only four I need in my 85 firebird. now under your pass. dash is your computer. you pull it down and disconnect the harnesses. In those harnesses find and cut the wires you need. The rest of the harness should be able to be pulled through the passenger quarter panel (you need to pull the interior panel between the interior and quarter panel on the lower pass side.) From the hood side pull the wire harness through toward you and disconnect the wires from their sensors. Your computer is now removed. I think you can connect the fuel and fan wires to the ignition relay. I just put mine on a toggel switch wired to a light. In any case be sure to put a fuse in line. Its really not hard at all especially if you even have a small clue about wiring.

 

I just did this in my wife's 82 Z28. I was a little scared to go massing with the wireing also but it proved to be easier than I originaly thought. If I had known about this board before hand it would have gone much smother also...lol. But I just unplugged everything from the computer and pulled it out (there were 2 of them actually a big one and a smaller one on the back of the bigger one)then I pulled all the wires out of the passenger side kick pannel and was supprised to find that there are 2 harnesses under the hood, one for the motor and one for the fuel injection, well guess what the one that comes from teh computer is the one that goes to the fuel injection so I just unplugged it from everything it was hooked to and threw it all in a big pile with the computer. Now with the fuel pump I pulled the tank down and took the factory pump out and put in a peice of fuel line that was the same length as the pump (so it would reach the bottom of the tank)and then put the tank back in like that and put a Holley blue pump inline with a fuel filter between the tank and the pump. I ran the power wire to the "ING" termanel in the fuse box so the pump comes on when you turn the key on. Her car originaly did not have electric fans but I put a duel electric fan set up in off of a Chrystler Concord (I have a friend that works at a Chrystler dealership as a mechanic and he gets them all the time... you have to love free stuff)and had to wire them up through a relay to keep them from dragging down the fuel pump when you turn them on. This is how her car is wired up and it works great. It was a little work but I think it was worth it. Now I don't have to worry "if I do something is the computer going to freek out and make it run like ****".
