Big change. How big?

oh god...south side is gonna go off on a tangent about how useless 305`s are...he`s gonna have his nickers in a twist for 3 days ranting about boat anchors, and scrap metal and soforth...(just kiddin southie)the 350 would be a much better power builder...changing to carb isnt that big a deal, as long as you can get it through emmissions...the trans can be reused if it already has a v8...there is a ton of really smart guys here on the site that can help you in every step...try doing a search for engine swaps for a third gen first...dont see what you`re lookin for, just ask...

Hmm, a 305 or 350 V8. If you have a V6 installed now, you'll have to change transmission along with the engine swap, bolt patterns are different from a V8.

Quite a bit of time and money for the change, but can be done. If you're going to change, get the 350 CID. More standard choices from the shelf.

I personally, dont really remember any v6's that had a different tranny bolt pattern than the v8's. Altho Ive only messed with a few v6's they all had the same bolt pattern as a SBC or a BBC. Only variation was not having a bolt hole at the top of the bellhousing. the block had it but the tranny didnt...but I could be wrong, I have been before.

Well, I suggest this because 2.8, 3.1, & 3.4L V6's (60*) have a different bolt pattern then V8's (90*), except for the 4.3L V6 which is a V8 minus 2 cylinders.

I also suggest this because he asks for a 305 & 350 V8. If car had a 305 to begin with, piece of cake, but he asked for a V8 changeover. I may be adding too much to his question.

2.8 had a 700r4 with a bolt on bell if i remember correctly...the bell is totally different from v8...much smaller if memory serves...(it usually doesnt...lol...)

Hmm, could be. I'm going from memory of an '87 S-15 with a 2.8 & auto. No bolt-on bellhousing here.

So I could be learning something new. Man, another thing/fact to remember.........

i just did a 00 s-10 4cyl eng and trans that had a 700r4 with bolt on bell...i wouldnt assume very desireable, but i`m positive it had the bolt on...my bad 4l60e...same thing though...i`ve got a mind like a screen door though...s#$% just passes right through it...lmao...
