Chevette V8 Swap Questions

I have a 1985 chevette that im swapping an 87 305 into, i know all the problems with the oil pan and firewall clearance issues. I just need some help with the electrical connections i will need under the hood. I know this is a noob question but i have never had to mess around with wiring harnesses. Any help would be great.

thanks

Hello.
Not sure bout the electrical connection, but I bought a 81 Chevette that was bout 90 pecent done with a mild built 355ci sbc and a turbo 350 tranny. Put in a new rear, added exhaust an a few things and that thing flat flew!!

If yer not adding a aftermarket rear, then you better start shopping the salvage yards for Chevette rears cause youll go threw em. S=10 rears fit pretty well.

Chk out my pics. I have a few of it ob there. Good luck, HG

Well this is an easy one.
As long as your v8 is carburated and HEI the hook up should be easy enough
Your electrical systems are the same
The distributor can be hooked up using the same wires . even your tach can be plugged into your distributor cap. the length may need to be altered.
Your starter and alternater wires can also be used. ( only the length may need alteration).
Even your electric choke wire can be used
Your temp sensor and your oil pressure wires can be used. Just adjust the lengths. of all your wires . Making sure you use heavy enough wires and good connections and you'll have an OEM appearance and no problems.
Love to see a picture when you're done.
I Had several of these Vetts my self

I had an 82' Chevette Scooter some 22 yrs. ago. It was my go-to-college-car. After we bought a house, I sold it. It was in really good condition, and was fairly low milage. I also had a FORD 260 V-8 with a 2 speed automatic. Motor was clean, had a "big" Holley 2 barrel carb on it, and I was going to put it in the Chevette, after finding a rear sump Bronco oil pan and pump/pickup. It looked like it would have fit in very easy by all my measurements. I'm surprised no one has done this swap. The little 260 was sure peppy in the 63 Ranchero rust bucket it came out of.

I wish I could find a Chevette 2 door in good shape, I would drop a 4.3 V6 in it modded with a larger roller cam and vortec heads, talk about fun factor.
A 350`s power in a shorter 6 cylinder package in a light car, sounds like sure sleeper to me.

So here's an update on the swap, i received an email from a guy saying that he had an 1981 2-door Chevette that was in the process of having a 4.3 V6 swapped into it. He was asking $300 with the engine and $200 without, so after about a week of negotiating with him i talked him down to $150 with the engine. All i had to do was drive 30 min away to pick the car up. I got the car home, cleaned it up, sorted out all the spare goodies he gave me. Then i pulled the 4.3 out and began making the SBC fit into the Chevette. I had to hack out a good sized section of firewall but it fits in the mounts that were welded in for the V6. There were some clearance issues with the oil ban but they were easily fixed with a body hammer .

i have a 84 chevette i want to put a 350 in it it has a 3.8 v6 in it right now. i like to sale the motor in it i like to leave it stock as possbile what would be the easys way to do that.

i want to do a 305 swap to my 81 chevette as well. i won't be able to start till next summer, but i wouldn't mind getting a heads up on any and all headaches you've run into, so i can prepare ahead of time.
