I recently purchased a 1986 Z28 Camaro that has a 400 small block replacing the original 305. The gauges for the oil,speedo, and temp guage aren't functioning. which i realize is because the 400 sb doesn't have the ECU comp like the stock 305. So what i am wondering is there a way to hook up any of these gauges or? I also need any information about the 400 sb.

Thanks

The gauges are not connected to the ECM. Each has its own sensor on the engine. Get a good wiring schematic. The oil and temp have different sending units depending on whether they're idiot light or gauge. As far as I know, the speedometer is connected via cable, just like the old ones.

correct. The gauges in that car are all connected to the individual sensors on the engine. The person who did the swap just got lazy and didn't hook them up

I agree, just get a wiring diagram and hook them up.

or didn't hook up the wires to the sensors. What trans are you running now? If it isn't the 700r or what ever came in the 86Z you will have a problem hooking up the spedo..I don't think they swap one for one if its got the 350th in it now, you may need an adaptor or different spedo all together. I bet one of those company that sells gages would be able to hook you up with the trans you have to the right spedo.

It has the original 700r-4 Tranny in it. I'm thinking of just replaing the 400 sb with a 350. The 400 runs decent, but it needs alot of bottom end work. Any other suggestions on other engines beside a 350 to replace the 400? I'd like to keep it a small block seeing as how it already has mounts and headers for a small block. I'd like something that has a nice mellow rumble with a roar when it's accelerating. Which by the way my car does have true duals with thrush glass packs (came with the car when I bought it) any opinions on exhaust mufflers/packs would be appreciated.

I'm running a 350 with edelbrock intake and rochester carb. Combine that with hedman headers and a mid range cam(485-286)lift and duration, and you will have a nice lope and rumble to your engine../mkf

My $.02...fix the 400. You won't find another small block that has the same torque without spending a lot of $$$.

I have a 406, 200R4, with 3.42 gears in my '86 El Camino. Great combination.
