i need help slant six

[nsalinas]

how much hp would i net on a stock 76 slant six origanally 100hp if i added oversized intake and exahist valves, 2bbl intake and carter carb, a 2.25 inch y pipe exahust system, and a performance camshaft with timing chain thanks.

You MIGHT add 50 HP...but probably not.

If you are dead-set on keeping the slant, a turbo or supercharger is a good way to add power. And you can retain some gas mileage with a turbo. But in the end, it will probably be more economical to just swap to a V8 - especially in a bigger B-body. An A-body is better suited to a turbo-charged slant because it doesn't need as much low end torque to get it going.

 

[RustyRatRod]

You can make respectable power with a naturally aspirated slant......compared to what a slant normally makes, but it will never be a V8. The reason to build a slant (unless you turbo it or blow it) is not to be a powerhouse. It's to be different. I have over 1K bucks in a slant six cylinder head. It's probably the baddest slant head east of the Missippi. I have flow numbers to prove it. Even still, if it flows 300 N/A horsepower, I will be surprised. I will be happy as hell, as that's the number I'm shootin for, but I'll be surprised.

You build a slant because you love slants. Not because you wanna burn up the asphalt. But because you like bein different. There's a guy over on FABO that has a N/A Valiant with a Lancer front clip on it. Mark Ethridge. He's run close to if not in the 10s by now with a N/A slant. His car is like 2300 pounds. It's a RACE car. Lightened up by any means necessary. If you don't have the kyoobs or a power adder, you gotta be light. Making something with a slant fast is more difficult than simply building a motor and throwin it in. It has to be purpose built and everything on the vehicle must be on the same page.

X2 all the above.

I had a buddy with a hot rod leaning tower of power and it ran mid 15's in a 70 Duster with a 3 spd. 318 valves, hot cam, header and 4 BBL. He used to take it to 6000 RPM pretty regularly and even let me drive it once, and told me to take it to 6K, which I did. Funny sounding thing it was.

Rusty, I think I know the guy you're talking about, that is if he's on the west coast. Gray old Valiant running low 11's. I spoke to the owner and there is so much done to that engine it's crazy. Overbored until the pistons touch and stroked if you can believe that. I believe it's about 260 cubes.

Naw Mark's is black. It's a stock stroke too. He holds the A, B and C gas titles....or did plus a nitrous title because he did add a shot of nitrous. This is an old video but here he is.

I've got a guy thinking of buying the 360 out of my car who's dumped over $2,000 into building up a /6 to get around 350 HP, and he's throwing in the towel because he's spent so much and is looking at having to spend a ton more on the effort.

 

[RustyRatRod]

You aint gonna get 350 outta a N/A slant. Ain't happenin. lol

 

[benno440]

i dont know how much HP it had but i did post the ebay page here a few months ago, cant find it though, some guy here in aus was selling his /6 drag car that did high 7's sec quarters N/A they claimed fastest /6 in the world.

ill have another look for the page

 

[RustyRatRod]

I believe you will find that that car had the Hemi six. I think I know the one you're talking about. It was a light blue if it's the same car.

 

[benno440]

i think your right,

did the yanks make a hemi 6 as well? i am pretty sure they made them here for our valiants for MPG reasons i think i read once

 

[RustyRatRod]

Nope. I sure wish them damn yanks would have though. lol

 

[benno440]

i remember them being a good engine, they used to race the hemi 6 in the valiant chargers (ugly car) against the ford falcons and holden commodore v8's the mopars used to smash them on the straights but no good on the corners

 

[RustyRatRod]

I think the Valiant Chargers are awesome lookin. You've got some screws loose. lol

 

[benno440]

if you like girls cars then sure haha, nah each there own but i cant stand there bland look, a little similiar to a 67 barracuda i reckon
