91 s-10 2.8 to 4.3 swap

I have a 1991 S-10 That has a 2.8 and a Borg warner T5 5 speed trans/ which is the same trans in a 84 camaro i have. I was wondering if the 4.3 would bolt up to the bellhousing or if would have to change the bellhousing?

Thanks

That would be a negative. The 2.8 is a 60* motor whilst the 4.3 is a 90* motor, so the bolt patterns on the bellhousings are completely different.
