Thread: using 4.3 chevy v6 to swap into afiero

Tweet

I am an old poncho guy who believed that you must have a man size car with aman size motor[66 grand prix /455 cu in]I have now become legaly blind and have bad feet.My 1 car garage no longer worked as aplay center.My wife allowed me to buy a fiero as atoy.SO.....there are adapters to use v8 too much for a69 year old.Many of the pieces for v6/v8 swap. SINCE I played poncho,I need to learn about its little friends[262 v6 350 v8]What must I LEARN ABOUT EXTERNAL BALANCE?what harm. balancer goes with v6/v8 flexplate.This is the first quest.If any one is willing to converse with adumbass geezer I WOULD SURE APPREICIATE IT.thanks phil the geezer

Simply use the 4.3L V6 flex plate or flywheel. It has the correct imbalance for that engine. Same advice for the harmonic damper/balancer.

thanks bob. will the torque converter from the th125 trans bolt up to the standard v6 flex plate? keep answering and I will keep asking. thanks again phil the geez

I think you'll need an adapter. Check out www.v8archie.com for Fiero swap info.

THE kit contains av8 flexplate,as does archies,neither of them has v6 stuff.Thats why my question on balance came from.THE ADAPTER converts bellhousing differences ARCHIE uses a differnt starter and spacer to make up differences .I find nothing onusing flex plate conversion.If my way of explaining things I am sorry.This ts the first forum site that will accept my email information.thanks for help....keep answering Iwill keep asking

As you probably know, the V8 flexplate has the same bolt patterns as the V6. If you can't find a conversion flex plate for the V6, you could have the V8 flexplate "imbalanced" to V6 spec. Any good engine shop with balancing equipment should be able to do that. They may have the weight spec, or if not they could use a stock V6 flexplate to determine the imbalance, then imbalance the V8 plate to match.

O K bobIthink that who ever does the engine will know what to do with the problem.Since this car is a toy,part of the game has been to find parts on ebay cheap,When I was healthythe game was played at carlisle and other flea markets thanks for advice phil the geez
