This stuff makes me laugh. Bobs talking about embarassing 350's. If they don't make 500 HP embarassing. When 455 iron headed motors making 500 are considered a decent powered motor. I agree 500 should be not that hard with the right combo of parts and there has been some effort to make that better but we need more in my opionion which is worth nothing for the most part. I think the guy's wanting to add boost are smart less money involved based on how they are doing it and still reasonably dependable. We are working on my sons first engine as many of you know from post on here. He for the most part is working on it himself with some fairly watchful eyes keeping him straight. Anthony is only 15 and will be 16 in may this will be his first car so we are trying to keep it in check. I think we can make 350-400 with 8.00 to 1 and we will once he has raced a little we will add boost via a pro-charger. I think we will make over 600 that way and it will still be street driven. We plan to dyno before the install in the car so we will know for sure before long and I will post the info when we are done. As far as the 470 cfm no way, I have spent enough time in front of my super-flow 600 to know that didn't happen at 28". And I would be surprized if it did it at .50 hg which is how they measure alot of stuff metric version.
Have you not heard of Sonny Seals 540 NA 350? Or Rob Margels 550 hp NA Pumpgass 350? Never heard of Daryl R and Buds circletrack engines that made well over 500 hp NA back in the 80s? I simply have not built a RACE ONLY NA Buick 350 but when I do I can garantee it will be over 500 hp, but I'm having more fun building not streetable BUT STREET FREINDLY engines that will make 600-800 hp with 10-15 psi using basically stock buick 350s and some forged rods and pistons. Thanks for setting my HP goals for me! So how fast should my Skyhawk run to get respect from you? Any how fast are you running BTW? Its easy to build a 400-450 hp and similar torque NA 350 but beyond that street manners will be compromised in most cases. Much funner to be able to drive casually at 2000-4000 rpm without low vacuum, loss of throttle response and torque on the bottom end, and the requirement for premium at all times that come allong with a high compression heavilly cammed barely streetable NA engine. My aproach is to run a little boost on my 398 hp engine and make an easy 600 hp without breaking a sweat or compromising street manners. Should make for a fun ride being my Skyhawk will be well under 3000 pounds.
Oh, and Bill M made mid 500 hp with his 8:1 engine before the boost. Also using pretty much stock 350s they were making about 700 hp wih the procharger before they build the serious engine. My serious engine is still in the works and I'll be hunting for the 1021 hp # BTW.....
I agree with Mark. 1021.....been there done that. That should be the baseline.ou: Now...with a set of those 470cfm heads:shock: .....you could throw 30# at the 350 and make 2000+ HP.:laugh: And stop picking on Bob K. Mando. :bla:
Yeah my goals should be to have the first Buick 350 powered car in the 8s LOL!!!!! :bla: Oh, wait you already did that........:laugh:
[sean loses his mind. twice. errr, three times.] :idea2: you been shut up indoors too long or what? don't worry, Canuckistan should thaw out in another 4 or 5 months. :TU: btw; i was taking Tahoe's "already been done" as a statement that magazine articles had been collected and research had been done. i could be wrong about his intent with that though. he is being somewhat vague. i am familiar enough with most of the builds that have already been posted here on v8. the only thing i'll point out at the moment is that they were regularly pulling +550hp. in the 80's. out of less than 340ci. :Brow: with no power adders. i'll give you a chance to work out the rest on your own. all the clues you need are there. considering how long ago this was being done, it should embarrass us that 20 years later we would still be proud of 500. :spank: Any how fast are you running BTW? proud of your wang yet? you should have noticed by now that i don't do the straight line thing.
I meant it in the context of 500hp out of a buick 350 has already been done... I guess if were were to get magazine articles, all of the buick 350 community would have to write letters to the editors of the magazines to get their heads out of their as$es.. now, big HP 350 guys, if you would be willing to perhaps post your full name, city where you live, HP achieved, and your email.. if everyone could write a letter, or send an email including said names, etc... perhaps some poeple will eventually get contactedo No: Wes
Bob You have me here I have sat here trying to come up with who was building 550 with less than 340 inches. Nascar was the only thing I could come up with and there was nothing Buick in those motors other than the name on the valve cover Chevy shorts with custom Buick heads that won't even fit on a Buick motor. Enlighten me because I would love to look deeper into it I'm all about learning more than I know right now at least point me in a direction.
dunno Bill, he seems to dish out as much as he's served! i'm flame proof and i'm a fire starter as well as a flame thrower. it's a dangerous combination. Your hilarious Bob, thanks for the encouragement! :TU: another hint: Smokey Yunick. uzzled:
Well i found this info so can you fill us in on the remaining info please? "For the next 10 years, Hot Rod and Smokey enjoyed a close working relationship thanks to C.J. Baker and Buicks Herb Fishel, who loved Winston Cup racing and also had an interest in high-performance street rodding. During the late 70s, he saw a chance to make the Buick V-6 the 80s alternative engine to the Mouse motor and hired Smokey to further refine the engine. Baker and Yunick then combined forces to produce a series of articles entitled Turn of the Century which chronicled the development of the Buick V-6 using as many heavy-duty OEM parts as possible. The result was a 355-horse V-6 streeter that found itself in a 78 Roadmaster, which was ultimately taken to Riverside International Raceway and testdriven by NASCAR-champ Cale Yarborough. In 1979, Baker and Yunick teamed up for two other projects. One was a supercharged V-6 that was installed in a Deuce highboy roadster built for former HRM editor Lee Kelley by Total Performance and driven by Baker and you-know-who from Memphis to California. The other project was a 355ci what-if alky-burning, Hilborn-injected small-block. The boys at Indy were contemplating a return to normally aspirated engines, and Smokey couldnt resist building a prototype V-8 using parts for his enormous pile of former racing inventory. The engine produced an easy 675 horses, but USACs return to a normally aspirated stock-block formula never materialized. Smokey wrote it off as another green card fiasco and went back to working on his controversial hot air engine."
can you fill us in on the remaining info please? i'm busy scanning and rescaling pics so i can host them at photobucket. just got into a huge stash of Circle Track mags as well and they've got quite a few articles on this so i may be at this for a little bit. PRODIGY? lol.. haven't heard them in YEARS it's been a long time since you've heard Prodigy? got to have been a lot longer since you've heard J.Geils, doesn't it? i've actually got that J.Geils band song. on cassette tape. ou:
you start poundin on her door and you say "Open up the door bitch! This is the wooba gooba with the green teeth, let me in!!" :beers2:
Green teeth!? Wooba gooba bitches? What the hell does any of this have to do with aluminum cylinder head rumors!!?? C'mon guys, lay down the crack pipes and back away, slowly.
there was nothing Buick in those motors other than the name on the valve cover Chevy shorts with custom Buick heads that won't even fit on a Buick motor. are you certain about this Bobb? when these v6's were making their push into circle track racing Chevrolet tried to fight back against the Buick block with their own 90 v6 based on the SBC as well as a 60 v6 that was their own design. you could be getting these three engines confuseled. i'm seeing that there were sometimes some Chevy parts ( valves and such ) used but that there was a lot of cutting done before they would fit the application. i was looking at these engines as a roadmap for modifications and parts that could be transfered to the standard SBB v8, especially the 300 ( since that's the block the v6 is based on ). if there's one thing circle track guys can do it's get "durable power". most of these engines are designed to run for a whole season of full on racing ( often thousands of laps ) with no tear down. it just seems stupid to be throwing away 3 years of research from Smokey Yunick and ~10 years of circle track development that went all the way up to the Grand National series. i'm not much concerned about "custom parts". this is a thread about aluminum heads for the 350 after all. failure to interfit with the production Buick design would be a rather large monkey wrench.
