Do they make an adapter that I can use to mate a chevy 350 engine to my v6 60⁰ 700r4. I've tried looking, but all I seem to find one to go from a v8 bellhousing to a 60⁰ transmission, or am I just dumb and that's what I need? Please help.

 

3.1L to 350 ? Direct fit

 

Hi TP,

Are you 100% certain of that? The 3.1 V6 700R4 and V8 700R4 have a different case for the different bellhousing bolt pattern between the two engines. While the 4.3 V6 is based on the V8 pattern, the 2.8 / 3.1 / 3.4 are the "Metric" pattern, as indicated in this excerpt shamelessly lifted from Wiki ;

Chevrolet V8 pattern[edit]

This was so named because it began with Chevrolet's V8 engines.

• Chevrolet big-block V8s
• Chevrolet small-block V8s
• GM Vortec 4300 90° V6
• GM Iron Duke RWD inline 4 (early RWD Variants, later versions may use a FWD pattern, and have two possible starter locations)
• Jeep with GM Iron Duke inline 4 2.5L/151 in³ (1980-1983). These use a Chrysler custom Torqueflite 904 automatic transmission with an integral Chevrolet bellhousing. Do not confuse with later AMC 2.5 L engine that uses GM small corporate pattern (see below).
• Chevrolet Turbo-Thrift engine (post-1962)
• Chevrolet 153 Inline 4 (Chevy II, pre-Iron-Duke - includes the Vortec 3000/181 industrial/marine crate motor)
• Detroit Diesel V8 6.2L and 6.5L
• Duramax V8
• Generation III V8s with modifications. These modifications include an additional bolt hole at the top of the pattern, and attachment points for cast oil pans to lower bellhousing extensions, to reduce NVH.

GM metric pattern[edit]

Also called the GM small corporate pattern and the S10 patternThis pattern has a distinctive odd-sided hexagonal shape. Rear wheel drive applications have the starter mounted on the right side of the block (when viewed from the flywheel) and on the opposite side of the block compared to front wheel drive installations. The 2.2l S10/Sonoma had the starter located in the same position as front wheel drive cars. A rear wheel drive bellhousing is displayed at right, and the integrated front wheel drive bellhousing is displayed at the lower right (in this case, as a part of the GM 6T70 Transmission).

• GM 60-Degree 2.8/3.1/3.4/3.5/3.9 L V6 (also used by AMC)
• Buick 3300/3800 V6
• Cadillac HT4100/4.5/4.9 L V8
• Isuzu all 3.2 and 3.5L DOHC V6
• AMC/Chrysler 2.5L I4 found in Jeep Cherokee, Comanche, Wagoneer, CJ and Wrangler and Dodge Dakota
• GM Iron Duke/Tech-4 2.5L I4
• GM "122" 1.8/2.0/2.2 L I4
• GM 5.3L LS4 V8
• GM High Value engine

 

Yeah I take that back 😆

 

No biggie, just wanted to make sure we gave the OP the right info

And, to Mspangler ;

If your gonna put a 350 in your car, forget about adapting your V6 transmission and get a V8 one instead. The one thing I'm certain of, beyond the bellhousing differences, is that the V6 700R4 is a "lighter duty" 700R4 than the V8 one, it has less clutch plates and likely wouldn't hold up to your 350 (especially if your 350 is gonna be pushing any kinds of serious power). Also of note, the front springs are different between the V6 and V8 cars to account for the extra weight of the 8 cylinder engine, so plan on replacing those as well (along with every piece of the exhaust system) .

 

Ok thank you I'll look for a v8 700r4, and ya I planned on upgrading the suspension and all that good stuff.

 

Yeah, not gonna happen.

If you live in or near Indiana, I have a 700R4 that I am going to be taking off to sell this Wednesday

 

Thanks, but I live in Pennsylvania. I think I have someone I can get one from though.
