im lookin for a person that has the sameeverything but with a 4.3l

 

I think I understand your post.
The 4.3l was not offered in '86, wasn't even an option until 89 or 90.
To geta 4.3l or SBC V8 into your trcuk you also need to replace the tranny. Major work....

You could upgrade to the 3.4L V6 and pick up 25% more power. Its the closest your going to get to a budget upgrade.
