That sounds awesome! I sure hope your right!chevymaher said:...The 70 V-8 has the exact same engine mount holes in the block and head, as the V-6. Everything will bolt right on. Water pump, aluminum brackets, pulleys the whole nine yards...
Thanks for the support and encouragement guys! The swap is not something I needed in my life right now... but then again there is probably no better time than now to do it. I am very glad to hear that most everything will bolt up! That is a HUGE relief!!
I was aware there could be a potential issue with a missing bolt hole on the head, or that it could be fine. The heads and block are still stock. You say the brackets, as well at the water pump will bolt on... that would be awesome!
The van is actually used to haul DJ sound equipment, and lives in the garage. I recently replaced all the clutches in the 700R4 with new, when I was replacing a broken sprag. I don't really intend to beat it up (like I used to)... so I'll give the 700R4 a shot behind the V8. If it fails, I'll throw the TH350 in it... which has a really tight shift and new holeshot converter.
The motor originally came from a 70 Caprice driven by a little old lady, and had very low mileage. When I pulled it (and junked the car)... I replaced a crappy 307 in my Chevelle with it. I've always called 307's "dumpster motors". I grabbed a bunch of crap lying around the garage, an old Erson Stage II Cam, headers, Edelbrock intake & 4bbl carb, and threw it all together. The motor came to LIFE!!! I've never had a more torquey crisp little motor than this one. The car would burn rubber as long as you layed on the thottle! It has a real choppy rumpity rump idle to about 1500rpms, thens hits a strong torque range.
The Chevelle wound up being stored outdoors in a field for many years, and fell into rough condition. Eventually, I sold it to a good friend a few years ago, who is in process of full ground up restoration, but I kept the motor and trans (saving it for the Astro). I knew the V6 couldn't last forever... but I was starting to wonder. It really was running perfectly until it developed the tick, and never burned any oil. Oh well... I got my money's worth on that one!
I'm in the process of prepping workspace in my garage, as well as prepping the 350 with new gaskets ... which is all it needs. Low mileage, but 44 years old! LOL
