My and my friend are swapping out his 3.1 MPFI 92 RS for a chevy 305. We are almost finished with the engine. We bored it 0.30 over and installed lunati cam, pushrods, lifters and rockers. We also bored out the valves and put bigger vales on it. Took it to a machine shop and the compression and everything else looks good. We are now ready to put the engine in the car. I have made a list of things we will need after we drop the engine(remember, we are going from a cc v6 to a V8. Please tell me if we should add or change anything in the list.

---List---
Holley 600 cfm carb w/e-choke
Edelbrock Performer RPM intake
MSD Distributor
Holley Water Pump
Starter
Hooker Headers
Dual Dynomax Mufflers
Torque Converter Lockup Kit
Water neck
Moroso oil pan

 

You are going to need a wiring harness depending on what fuel injection you have, you are going to need motor mounts, upper lower radiator hoses, Surpentine setup and ac lines, alternator, battery cables, new trans, crossmember, and a ton of misc nuts and bolts. This is a very expensive swap unless you have a donor car.

 

You DO NOT need the wiring harness as you are going carb

You DO NOT need the serp belt unless your motor is serp belt.

You will need the v8 trans but it bolts right in place of the v6 trans.

The swap is not expensive unless your retarded and happen to throw away stuff you need.


Its not like your putting a ls1 in a 3rd gen, your putting a 305 in a car that could have came with a 305 in it. The holes for the motor mounts are already predrilled. Its as simple as pulling the v6 motor/trans . Trash the v six mounts and bolt the v eight mounts in the front most holes put the eight in wire up the dist etc rad hoses and wala

 

Yeah its not too bad ...you will need a fuelpressure regulater to regulate the factory pump...this is what I did..

 

here is where the motor mounts end up..

 

Riley did you have a hard time getting the v6 mounts off?

 

It was a PITA...and even tougher getting the v-8 mounts back on..takes alot of extensions , a magnet and about a 12 pack..

 

im thinking about grinding the v6 mounts off and using new hardware.

 

Make it a lot easier..I soaked mine in a bolt/ rust remover over night. It helped a lot.

 

you changing out your springs? I didnt and now I am running 28: tires with still no problem.

 

nah im gonna leave the springs, from what i hear from alot of people who have went v6 to v8 the v6 springs are ok. I could always change them later on.

 

good luck with you swap..let me know if I can help. Ive done a couple now. Later.

 

This is a costly swap belive me. If you want to hack up your wiring harness and make you engine look like a kid put it together by all means go ahead. When you open your hood to show your friends your work they will instantly know that it was a v6 before. On top of that if the engine is left stock then you will have a much harder time doing mods to it later on. Crank, rods, pistons ect. If you through on a v6 trans on a v8 it will not last to long. If you want to do a v8 swap dont bother with a stock 305 or 350. There is basicly no change in performance. One is quicker than the other but the 3.1 is better cornering wise.

 

The only way to possibly tell is by how the fuel lines are run...I could post some pics as of present..and you would never know it use to house a v-6...as for lasting , I had swapped a 327 in first..it lasted until I put the 400 in and I sold the 327 set-up for 600..what you are saying is just rediculas....

 

Ok there is no nice way to put this other than, YOU ARE A DOPE!

You cant bolt a v8 to a v6 trans anyway.

You go on with your retarded gibberish, its obvious you dont have a clue what the hell your talking about.

And motor size has nothing to do with cornering etc. that all deals with suspension work done to the car.

You must be one of those v6 trolls who hate people with v8s!

 

you use a v8 bell housing on a v6 trans therefore you are using the v6 trans. Sure sure i dont know anything. Its not like i did the v6 to v8 swap before (jk) now please no more false information. Yes cornering deals with shocks struts etc. however from the factory a v6 could out manuver a v8 simply because of how heavy a v8 car is. why do you think some civics are fast with only 220 hp. I also wonder why you sold the 327. Im not going to respond to anymore people without common sense. Good luck with your swap.

 

Because this car is all strip now. I wanted all the cubes I could get while keeping the smallblock.
My 406 is good for about 500hp N/a.
the only thing that makes a v-6 car lighter is the motor and tranny. Thats the ONLY difference between the two.

 

Sure as soon as you stop posting it!


Ever heard of ws6? 20somthing mm sway bar vs 30somthing sway bar? The v6's are not cornering better than the v8's. Thats a simple myth the v6 guys keep going to feel good about driving a slug of a car. Sure the v8 car is a LITTLE heavier, but along with that weight comes alot more tq than you get with the v6.

 

OK, if he is going to a carbd v8 why would the wiring look hacked? I just got done doing my wiring, and it looks fantastic. When you switch to carb, you only use like 8 of those wired in the engine compartment, everything else is removed. Now, to make it look good, as you remove the old wire, you save the looms that go over it and the clips, and reassemble them over your wires you have left. Actually, contrary to your opinion, mine doesnt look like it was ever a v6 car at all.

No change? are you mad? I guess that most 3.1's ran dead on with a 350, sure.

OK, I didnt notice anywhere that it said they were going to do this. BUT, if they are using an auto, you aint gonna switch bellhousing, and if it is a stick, then it is irrelevant, the T5 wont last long behind anything being driven hard.

As far as fuel lines go, if you dont want to have it looking like a v car, just move the line to the passenger side. The holes are already there to hold it up, everthings set up for it.

 

As per the stickie, if you drive this on the street, you're going to want to change the front springs. Otherwise, you'll be bottoming out and swaying more than necessary. I found the V8 springs even rode better.

Do you have to put in V8 springs? No, but you don't have to put in a V8 engine, either.

 

i left mine, just need a good set of struts. But, yeah, it does sit a little lower, and they never ride quite the same

 

5-7 is right (as usual) But my car very seldom makes turns anymore.....
When I had the street driven 327 in, on fast sharp or long sweeping corners, the nose would tend to dive a bit.
