Hey guys. I've been following this thread and am about to do the head swap. I am looking at a 93 wrangler donor engine tomorrow to make sure the head # is the 7120. It will be put on a 78
AMC 258 i6 / 4.2l engine. I want to keep this one the cheep within reason. I know you have to spend some money to make it right. Just want to know where to spend and where to reuse parts.
I have read alot about this conversion and have a few questions. Sorry if these are repeat questions.
1. Can you use the same
AMC 258 i6 / 4.2l intake if it is a 1bbl carb?
If so then I'll do that then upgrade. If not the what 2bbl intake should I get and what carb?
2. Can I use the same rods and arms? Should I get new ones?
3. New head bolts? 4.0 bolts or
AMC 258 i6 / 4.2l bolts.
4. Any onther advice......
Sorry for the questions. I'm going to read some more articles.
Thanks in advance,
Dan
