yes, the 700R4 transmission is the standard trans for the K1500 with a 5.7 350 engine. 305 is also with the 700R4 transmision.
no
Yes...they are the same bolt pattern.
Absolutely! It bolts to a 305 exactly the same way it bolts to a 350... It's completely interchangeable.
Your question is a little vague, so im assuming you're asking which is better between 350 and 305 heads. Many people will tell you it doesnt matter. I think if you have a 350 engine then you should use 350 heads. the 305 heads will have higher compression, which will make the car louder, and somewhat faster, however, if you use 305 heads on a 350 engine then you should use a high octane fuel, so it will be better on your engine. Only use 305 heads if you know what your doing. if not you should probably stick with 350 heads. i hope that answered your question.
Yes you sure can. There the same.
What engine is it in? 305/350 V8s use 5L of 5w30 in the winter and 10w30 in the summer
yes its the same but i wouldn't recomend using the stock trans unless rebuilt
The headers for a 350 and 305 are the same.
If you are a good welder, and know how to use a torch you could put a 305 Chevy v8 with Tranny. It just how much time,money, and fit and finish you want to spend on it.
Yes, but you must keep the lifters with the cam they were originally used with.
yes a350 trans and 400 use the same bellhousing
