I have an old 1989 van that is just getting too rusty. But the engine and transmission have always been very reliable. Is it worth pulling this motor to put in on OBS/Gen3 truck or even an old European car? How easily would this motor mate up with a manual transmission?

I'm basically wondering if the Vortec is just better for those type of swaps, making my old TBI of no real use.

Thank you!

Well if you can use it pull it. if it's just going to sit then you should probably sell it for a few $100 bills. 700r4 is a good transmission for swaps. any motor will mate to a manual transmission if you have the bell housing, flywheel, clutch and shifter.

Would my L05 be a mostly direct swap into a 1998 Silverado 1500 4x4 with a 305? That's one application I'm thinking of.

Isn't the bellhousing for the 700r4 in the g20 van platforms a little longer? I read that in a Chevy/GM van forum.

I'd say it's worth it. My Papa (Dad's Dad) was a Ford Engine and Transmission tech for 43 years. He said the vans were a huge PITA to work on bc of the space inside (or lack thereof). So pulling out the engine and transmission and swapping it into anything else will make it much easier to work on.

This motor should mount to any manual transmission that was designed for a 1st gen SBC. I took an auto shop class my junior year of HS and took apart and "rebuilt" a 350 SBC built in 1973. When my friend and I were rebuilding his Vortec 5700, the block and internals looked exactly the same as the 73 motor.

Vortec would be better in terms of power and fuel efficiency, but they're tougher to work on and a lot of people prefer TBI bc it's a lot easier and cheaper to work on. IIRC TBI engines use the same intake as carb engines bc TBI is basically just a computer controlled carburetor. If you ever wanted to carb swap your L05, you could go that route too.

The TBI intake is not the same as a carb in take. The center 4 bolts are drilled at a different angle.

An L05 is not a direct swap into an L31 truck. There are several minor differences to overcome. However, a good running L05/4L60 is worth a few hundred dollars to someone needing a drivetrain.

L31 being the 305? What are some of the problem areas with that swap?

Also is my transmission also called a 4L60? My understanding was that the model name is 700r4.

So would you think this motor could go pretty much directly into a L05 OBS?

L31 is a 96+ 350 Vortec
