4.3L v6 questions

[hoogiesngrinderz]

Why a 4.3? Those don't make any power I can run as fast as those would go.

They make plenty of power for what they are. The guy who did my heads runs high 12's N/A with his DD 4.3.

Highs 12s my Dads colorado will run that lol jk.

They're not bad motors I wouldn't run one but it's your choice I wouldn't tho.

it was a zr2, i thought it was a colorado because his zr2 was yellow and ihad a friend with a yellow colorado.

so wait, your going to put this in a thirdgen?

[TylerT/AZ28]

most likely

most likely

can I ask why?

[TylerT/AZ28]

short version: sister get liscense says she wants a firebird, sister is moms favorite so gets what she wants, mom cant find cheap car which i told her she wouldnt, tells me to build one for her. therefore my ideas are hard at work. she seems serious now but a few weeks from now who nows just gotta see what im gonna get my hands into if she ends up buying stuff for this instead of going in blind with no clue.

[Darren]

ok so she wants a firebird and wants a thirdgen, or 4th gen? Because you can buy one for cheap, especially a v6 4th gen... By the time you buy a roller and buy a motor buy a trans and get it all up and running and presentable you could have bought a v6 4th gen already and had a lot less work and frustration. However back to the 4.3v6 why that motor? I mean if you just want a driver and its for your sister, get a 305 for probably about the same cost and a lot less work everything would be plug and play and you would be done in no time and it would not be a dangerous motor for your sister to own/drive. Also running properly and driven well a 305 and net "decent" MPG's for a v8.

[TylerT/AZ28]

because a 4.3 is actually a pretty good engine. yes i know you can get a 4th gen bird for the same but thats not how my mother sees it although ive explained it numerous times. then theres her complaint that all v8's are bad on gas and are too fast. trust me darren ive been there and back but when your truing to do something for someone else its more of what they want.

[Darren]

well in that case I'll just outright say it, your crazy to put a 4.3 into a thirdgen, there I said it. There are much better, more efficient and smarter ways of doing it. Now if you told me you where doing it to be "different" for some odd strange reason, ok I can appreciate different but your not, so its crazy. Talk some sense into them, if I was you I would be refusing to do such a thing. Its going to be a lot more work and a lot more headaches then your assuming to do that.

Go with a 3.8... way better gas mleage than a 4.3.

4.3 vs a 305


Same power
same MPG

Funny fact. My 94 blazer with the 4.3 vortec is rated at 200hp
My old 1986 IROC with a 305 TPI was rated at 190 hp

305 easier to install into a thirdgen, plug and play...

[TylerT/AZ28]

darren ive already tried, imnot arguing with them anymore. you just told me a whole lot that i alreadys knew

[hoogiesngrinderz]

Turbo 231!!! I'd do it in a heart beat if I had a good thirdgen roller.
