1986 258 inline six swap to a 1991 4.0 H0 fuel injected motor

[Quick2]

I was thinking about going this rout because I am sick of the crappy carb on the AMC 258 i6 / 4.2l and really want fuel injection. But now I'm leaning to putting Fuel Injection on my AMC 258 i6 / 4.2l . Fuel Air Spark has a new kit with everything you would need but air cleaner for 1769.99. Looks pretty sweet.

Thanks for the site "Fuel Air Spark". Looks like they got lots of cool stuff.
Someone mentioned I should my my 4.0 TPI a stoker. Did a search and found out about that. Looks like you get max tork at a lower rpm with the AMC 258 i6 / 4.2l then the 4.0. Think I will wait for my 4.0 to need rebuilding for that. At this point am leaning on getting the wiring harness for the 4.0 and a new header and exhaust. I am having the rear axle rebuilt this week. It has a tooth missing on the ring and pinion. Then on the engine.

The 4.0 I got to replace the AMC 258 i6 / 4.2l turned out to need rebuilding.
Now I am thinking of buying a stroked 4.0 to put in. With the engine and wiring harness I think it will be about 5 grand. Any one no of these guys.

As long as it has a good warranty you should be ok.

To do the conversion, which is quite common. This will be a good long-term option, if you do not rush to HP 97 establish once.
