Slant six to 360?

Of course you will need a sb distributor but the ecu is the same between the 6 and 8. if you are going automatic you will need a sb tranny, if you are going 4spd you will need a sb bell housing and clutch.

I did this Back in 05 and IMHO these are the steps.
1. Unless you already have disk brakes that is step one to upgrade to them.
2. You need to upgrade the suspension. The /6 suspension is barely adequate for the 6 and unacceptable for a sb. I went to big block torsion bars but many others go even bigger. I also installed XHD leafs out back.
3. The stock 7.25 rear should be replaced with an 8.25 or a 8.75. You can get by for a while on the stock one but you will have to drive as though it was still a 6.
4. The cooling needs to be upgrade to a v8 unit.
5. Now you can do the engine swap. Don't forget the exhaust.
