Thread: Chevy V6 help...

Tweet

The Chevy 4.3's are excellent engines with a lot of power and torque. Have one in a Chevy Astro van which is used to pull a 22 foot aluminum trailer with a 34 Chevy Master 2 door sedan street rod on board. Never any power problems hauling it from Florida to PA to Louisville and back. Decent engine.

A 4.3 is a sawed off 350 as others have said. It is NOT kin to a 3.8.

The TBI 4.3 was built 85-98 as I remember.
The Vortec name was used on quite a range from 85 up
The 02 up are Multiport and are option LU3 or LG3

All are 4.4 inches shorter than a small block chev (which is the bore spacing on a small block V8)

transmissions, water pumps, timing covers, motor mounts, and front brackets are same as V8

Thanks guys. do you know where i can pick one up in australia? it doesnt have to be in good condition, coz it will rebuilt most likley.
thanks ben.

A lot of S10 trucks have them as well as the full sized Chevys and GMC trucks. Look for typical Chev valve covers and water pump.....the neat thing about a 4.3 is the commonality with the 5.7......parts are easy to find and cheap to buy.....

thanks for that. i'll keep my eye out for any on the tdaing post or sumthing like that. any where i shood look out for em?

Thanks Ben.

The 3.8 is a sawed off 327 & a 4.3 is a sawed off 350. GM G-bodies used them(78 to 88 Buick Regal, El Camino Malibu,Grand Prix & Cutless),both the S-10 & full size Chevy used them.

The later 4.3's are pretty sophisticated little engines. Roller cams, good Vortec heads, etc. I built a '97 out of an S10, and it has all these goodies, and is a great running motor. You can get aluminum intakes, cams, headers, etc to wake them up even more, and to get rid of the fuel injection, if you desire.

With gas prices climbing, they are a pretty good alternative. The one we built for the boat is very fuel efficient.
