What is this, is Dart making a Buick style rocker shaft head for a chebby or are they adapting the better flowing Buick head to their block? Has anyone else seen these heads in use. I have plenty of friends that swear by chevys and they say they have never heard of such an animal. A quick search of Darts web site brings up a Buick head for Chevy 350, am i having bad trip and don't know it?
Yep! :laugh: They came out quite a while ago (don't remember the year). I think it's a Buick V6 stage II chamber and ports to fit a SBC. They were the hot ticket back then, too.
They'll mock our engines but still use the heads........at least when the chebby explodes the heads will still be intact! p
They were the hot setup at one time though they are a bit obsolete today. A friend of mine just got a whole engine with those heads. A 377 that makes 760 HP at 7400 RPM. Peak torque about 500 ft-lb at 6200 RPM. They have huge ports and are a super high RPM setup. Not for the torque-minded. The fun part is reminding him he had to put a "Buick" in his Nova to crack the 9's (assuming it does).
There's a "Pontiac" SBC head, too. There are Olds "Drag Race Competition Engines"-DCRE- blocks and heads which are super-duty BBC items with the Olds logo on them. And the Olds "Rocket Block was a super duty SBC variant with an Olds logo. What I don't understand is why people still think the new LS1/LS6 engine and it's variants is a Chevy design.
the heads were originally used for the nascar regals back in the 80's. nascar said you have to run a buick style setup....so thats what you see. all chevy except for the valve train. worked, bobby allison won some races. john
The Buick heads are old but they have been trickling down for over ten years . They are "spread port" which is nothing like a true buick head. Different valve angles port design etc.There are some guys still using them in comp but they are kind of down on power compared to the current splayed valve stuff. There is an olds rocket Small block and corresponding head and the head looks very like a splayed valve big block chevy. Then there is DRCE I,II,and III. DRCE III is the latest NHRA pro stock stuff and where almost everone has switched to . It has a deck height close to a small block chevy but with the right bore spacing a bore size of close to 4.700. This family is "kind of" a big blck chevy technically but nothing from lets say a 70 454 motor would actually fit. Not even a valve cover. My stuff is DRCE II. The III stuff is just not common enough as a trickle down yet(still too expensive). Now ya know. George
1997 Ford Probe Competition Eliminator B/Altered 459 inches 1160 hp eeep! what the heck have you got in that thing? a BBB? how does that work? :jd:
As a function of pure $$ I'm sure, just like every other Comp combo I have ever seen. Those guys really squeeze some awesome power out of some small cubic inch stuff, and it's one of the most exotic and expensive classes of NHRA racing. JW
LS1 and LS6 is an engine used in a few different GM cars in which the engine is used because GM is all corporate now. I think GM should go back to having the cars use their makes own kind of engine. Never heard of a dart head for a buick to fit a sbc. Guess ya learn something new everyday.
squeeze some awesome power out of some small cubic inch stuff see, when 459ci is considered SMALL i know i've crossed over into some totally alien world. :laugh: i was actually more interested in how he stuffed the V8 into the engine bay and got the trans in there as well. i've got a probe and there isn't hardly room for the v6 much less a v8. i'm assuming a total custom subframe and he probably had to push the firewall back. not that getting rid of the rear seats in a probe is any great loss anyways.....
The Probulator My probe was never a real Probe , it has a steel roof and quarters and the rest is all carbon fiber panels with a tube chassis. The car was a prostock before I got it with a 500 ford engine. I am a GM guy but didnt want a camaro or whatever. We took a former Larry Morgan 500 inch motor and destroked it to make the 459 inch combo. The rest is all NHRA pro stock stuff--Liberty 5 speed, 8 inch dual disc clutch (last year --now going to a dual seven inch), nine inch sheetmetal rear ,four link etc. It is the OLDS DRCE II block and heads. Very un Buick like -- I leave the starting line at 62-6400 and shift at 9200 rpm then go across the finish line at 9400. The Buick stuff is my street car...
I have a bunch of IHRA prostock friends and they call my stuff a small block... I dont think your probe can do this burnout
