ok so i turn 16 in january and my first car is going to be an 83 malibu wagon. the only thing ive done to it is i put 02 S10 wheels and new tires on it. now for the good part............the engine. i bought a 94 blazer with a 4.3 vortec v6 that i was gonna put in it. but i LOVE the sound of a v8. what do you think i should do????

305/350 vortec v8 or a 4.3 vortec V6

if you say v6 what should i do to it to make it a hot rod engine??

You could use the 4.3 V-6 and ad a few mods to it. Headers, new intake manifold and carb, optimize the ignition. I'm sure you can get the 4.3 to sound and run pretty good. Being that you already have the Blazer as a donor car.
What engine is in the wagon currently?

it has a 3.8 v6 right now

if i kept the v6 i was thinking headers, dual exhaust, cam, and maybe air intake

but if mpg would be the same as the v8 i would probably go towards the v8

so i'm probably just going to keep the v6 and build it up

but what do you suggest i do to it?(don't say turbo/supercharger)

i was thinking .30 bore, headers, dual exhaust, cam

i want it to sound like a v8(and have lots of power)


keep in mind this will be my daily driver

thanks

Not to burst your bubble but it will never sound like a v-8. You can make it sound good but a v-8 has a sound to it as does a v-6. However if you plan on going through the v-6 it won't be anymore money, maybe less to build a sbc. But you will also have to get a radiator and a few other things to change to the 8. One more thing is the 3.8 a 229 or 231. If it's the 229 I don't think it's worth messing with, if it's a 231 it will be Buick motor and there is alot out there for it.

^ i agree. If your going to go threw boring it out and all that other fun stuff. It would be less money and time just to get a 350 from a junk pickup or somthing. I found my 350 from a wrecked 70's pickup. I baught the whole truck for 250 bucks. Slaped and edelbrock performer intake and 600 carb on it, got some tune up parts, and its been in my caprice for 15,000 miles now with no issue or problems at all. I have 500 into the motor. It goes pretty good and gets between 17-20 mpg depending on my foot

I built up and put a blazer vortec v6 in my 80 El camino. It is backed by a 4 speed stick. Id say go for it, but its going to cost you alot more than building a v8 if you want to do it right. I have big block money into this thing. I could have built an LS motor for the same cost. But this V6 is built right.

i'd just make it look nice and keep the 3.8 in it for now. just clean it up as best you can so that you can take pride in lifting the hood. save you pennies and in a couple years when this is no longer your daily driver, drop a v8 in there.

Unless you have the budget to also upgrade the trans (or can keep your foot out of it) you may want to reconsider at the moment. Cleaning the engine compartment like grizwald said will probably be a good starter. I'm guessing you don't have emissions there... if you want to build the 4.3 you can go with a carbed setup to keep it somewhat simple, but it still has the capability of making a decent amount of power (around 300hp based on the build below).

Whatever you do, don't copy the "Hot Rod" 300hp V6 buildup. I currently have a 1985 4.3 V6 with an Edelbrock Performer intake, a Holley 4160 carb and headers in my little red wagon. The engine runs reasonably well, but I have yet to get it to produce the kind of mpg I wanted from this setup, suggesting that the Malibu wagon is a bit heavy for the 4.3. I think the "Hot Rod" buildup is better for something in the sub 3000lb weight range.

If you're up to converting your wagon for FI, you might want to fit your V6 with a pair of shorty headers and drop it in as is. Otherwise you might want to consider a V8. If I had known about the following buildup, I would have gone with a 305. If you go with a 96-99 Vortec 305, you could use GM Performance's 14097395 roller cam (288/308 advertised duration; 196/206 [email protected]; .431/.451 [email protected]; 109 sep)
and have a street engine that has more punch than you'll get with a normally aspirated 4.3 and good mpg. Oh, and it would sound like a V8.
