Anybody evah do a hot 4.3 before? Sound kinda neat. It would be super light too. Just an idea.
The 262 V6 sounds really good too. I had one in an 85 Caprice coupe once. You couldn't peel out, but once you got moving it almost hauled ass.
-
Had one in a 92 s dime. Throttle body spacer, open element k&n, headers, msd all around, electric fan, gear drive, that's about it. One mean truck to a 16 yr old kid. My buddy wrecked it trying to drift... Only one kind of truck I drive now... FULL SIZE!!
-
GM did. They put them in Syclones and Typhoons.
And they are not "superlight" compared to an iron SBC. But basically you can build them the same way as a 350, pretty much. Build one like you would a 400hp 350 and you should have a 300hp V6. But this, to me, seems even more pointless than hot rodding a 305, unless the application can only physically fit a V6.
-
It might seem pointless, but a 262 V6 would be a cool build since it's different. Everybody has some form of 350 V8.
Screaming down the road with say, a 280 horse 262 might be a lot of fun!
I remember a magazine did a build called "The 3/4 350". Got some respectable numbers out of that thing.

Yeah, that's pretty much exactly what I was talking about earlier. With the same investment (financial and labor) and the same sized cam, a 350 would have made 400-425hp. If you want to be different, drop in a big block from another GM brand. Don't go smaller and weaker. I mean a Honda 1.6L would be different, but you don't see anyone swap that into their hot rod.
I see what you mean, though. Just for grins, it could be fun to try and make a high hp V6, but not if you REALLY care about going fast.
-
I personally have never liked the 350... but I guess the 400's very close
-
The only reason 350s are more popular than 400s is because GM made gozillions of them, while the 400 only had a limited run. If the 400 had been introduced in the 1st gen Camaro like the 350, things would probably be different.
-
It's always that epa that ruins all the good stuff ::)
-
I wouldn't be caught dead with a Honda anything. Another reason to hop up the little 262 is if maybe you had one laying around taking up space and you just wanted to see what you could do with it. I still think it would be a cool build. Of course if given the option of either a 350 or the V6, I'd take the 350. It's just that even though the 350 small block Chevrolet is one of the best motors ever made IMO, you have to admit that sometimes it just gets boring.

What's not to like? Cheap and easy. Very versatile. Parts readily available. Very reliable. I'm in
-
Dunno. I guess when I had my s-10 everyone said 350!! I'm like no thanks. Then with my c-10 I just kinda wanted to be different I suppose. My dad's 97 sierra is a pooch to me, and my 88 throws every dtc in the book. Dunno really, just like being different ;D
-

I'm still kicking myself for not buying a Honda, at least out of respect for Mr. Honda.
-
Different is good if it serves an innovative purpose.
-
Forgot to mention that my g/f 89 camaro with a mildly built carbed 350 got annihilated by my buddies 91 crx with a built b18a1. But a lot of people around here have their c/ks with 350's or bb's.

Drop that 350 into your Citation and surprise the heck out of that CRX. :o

I had a fullsize with a 4.3 and I dont think that you could make it hot enough to make any kind of difference. I have also had a hot 4.3 in a S-10(supercharger and all), the little truck was quick and had tons of power but this was all due to the weight of the truck. That same motor in my 84 would have been slow.
-
I'd love to put a 455 in my truck. Doesn't matter which really: Buick, Pontiac or Olds. They all make power amazingly easy it seems. Determine which stock heads were good for power, put a decent size cam in, good flowing intake, carb and exhaust and you've got a 13 second machine. Follow HAULIN IT's recipe and you could have a 12 second mild-mannered truck! Either that or a Caddy 472/500. Any of those would just be too cool.
-
I think a Cadillac 472/500 in a C10 would be way cool!
-
Consider this one... Turboed V6 out of a GNX haha
-
Turbo'd 4.3 from the Sy/Ty as mentioned already was as ballsy if not more so than the GNX motor.
Speaking of GNX, I read something horrifying lately: a GNX was actually turned into the Cash 4 Cars rebate program. :o According to a list in Hot Rod magazine anyway.
-
Only one... Thank God. Lotsa corvettes and other NICE cars.
-
Come to really think about it... The 262 V6 would look microscopic in our huge engine bays! You could basically stand under the hood to change spark plugs! I still like this motor though. I'll never forget my 4.3TBI 2 door B-body that was a blast to drive. Until Mustangs wanted to play. >:(
-
My 262 goes like stink ;D 57trim John Waller turbo, hotwired IC, intake, straight pipe, AFPR. Laid 4 black patches with it.
-
I still like this motor though.
Yeah its a great little motor and I love it in my s-10. Its a lot of fun in that truck, as matter of fact I had it crossed up leaving the gas station earlier ;D
-
I give respect to the Syclones/Typhoons, but dont like the exhaust sound of a V6. I like a little rumble to the exhaust
-
A lot of modern sixes sound weeny, I have to admit...but there's just something about a classic inline that gets me everytime. I used to have an old Ford 1/2 ton that everyone swore had a V8 until I opened the hood....300 inline six rumble!
-
Inline 6's do sound pretty good in my opinion. Im planning on installing a split exhaust manifold, and Clifford intake on my 51. It would sound good to me because it matches the era of the truck. An I6 would be ok in our trucks, I just dont like the sound of a V6. I like the 4.3 engine, but would do my best to keep the exhaust stock.
-
In 87 wasn't much difference between the 4.3 and the 305

When I had my hopped up 4.3 it sounded good with the dual exaust. With the cam it had in it most people couldn't belive that it was a v-6.
-
Beat by a 305!...That is some great reading right there! Hard to believe that was almost quarter of a century ago! Time flys.
-
i had one in my s10 bored .030, headers and a holley 600 cfm dual feed carb. was plenty of engine in that application. i wonder how it would have done in a c10.
-
I have a similar setup on my v6, headers, bored .30 over, and a 650cfm Edelbrock carb......its ok? It moves haha I wish I could find something to boost it up to around 250? Its really not feasible though without the heads Brodix USED to make....unless someone can correct me?
-
not to jack this thread but what would be an appropriate came for that? with keeping stock lifters etc.....the engine was only rebuilt 30k miles or so ago.?
-
my 4.3 came stock with 9.3-1 compression and big valves. Considering that; i think 250 would be very feasable. mine was in a 2wd swb s10, 4 speed and some pretty short gears. so it was plenty.
-
I wish the factory put better cylinder heads on the 194,230,250 and 292 engines. I believe that is the main object holding these engines back from making real serious power.
-
Hows this? ;D

You can try a super-toro-charger ;D

That Nelson 4.3 is amazing!!! He builds some serious engines. The only problem is that they are only for those with DEEP pockets. :'(

:D :D :D

OK 3 things/maybe 4:
1) nelson is willing to negotiate on prices since the economy is bad; He was recently on adam corolla's car podcast---a very good podcast if you are hardcore into cars.
2) i also thought that the 4.3 weighs pretty close to an v-8 small block, but the article says it's 125 lbs. lighter?
3) The other thing i'm skeptical about is they were saying that the 305 got 20mpg and the 4.3 got 21.9 mpg. These were both 4x4 trucks with 31x10.5 tires. They didn't give the specs on the 305 engine. i'm not saying not possible, but i'm very skeptical.
4) i feel the 4.3 IS the engine to go with IF you're staying with gas and you want max mpg.
-
Stand out from from the crowd, don't follow it everyone and there brother has a 350 there in every hot rod out there, if everyone just followed the crowd we would all be driving rice cookers with soup cans for mufflers
-
That's why I have a hot rod 400 and did a 4.3 in my old s-10 :D
-
nice im puttin a built 400 in my 85 lwb should be a ton of fun with all that low end grunt
-
If it was easier to supercharge or turbo them they'd probably be more popular than what they are, but their is a million better ways to go for you're money
