800hp n/a small block

Has anyone ever heard of 800 whp on an all motor 350? no boost no juice and no blower.

yea right. No way

I dont believe it either but there is a kid where I live that has a 80 malibu and he claims that he has a "build race small block" that is pushing 800 to the wheels with 8" slicks and he wants to race my talon so I was just wondering if that was possible or not

He's full of it unless he has a fortune. He might be pushed alot but nowhere near 800

pump gas: no, racin gas: most likly not (possible, not plausable), Alcohal: beleaveable

well he is claiming its a completely street legal dd with "8" slicks"

well first off you said kid, so that threw the big bs flag, no parent, not even a half brain dead one would give any kid, anywhere anything with anywhere near 800 horses... i would beleve crank hp on pump gas to 350ish possibly 4, and MABY up to 6 on 130/160 octain racin gas, i think 6 is a big push for it though... just on a footnote, you can get a 4.3l v6 up close to a grand for horses, if you port it out and put alcohal in it, and here in michigan, wheres we dont have a probe in our tailpipe once a year, alcohal IS street legal

well by kid I mean, well hes a kid no more than 17. he had a "build 355" in the car but it started on fire and then he gave the car to some guy who is probably mid 20s and he got a "full race small block" and put it in the car. I dont believe this kid at all and I'm not worried about it because even if he has his fabled 800whp there would be no way in hell he could ever hook up with his "8" slicks"

ive got less then 250 horses to my s 10 wheels at the moment, and i break my 8.5'' 20's loose all the time without trying...and 'race' heads on your small block chevys are reversed, instead of going (E=exhaust, I=Intake) eiieeiie they go ieeiieei, and to run those heads you need a minimum of 110 octain, if you see him at a gas station, every, its a lie......... lets step back for just one minut here... ever go to a dirt track for races?? I do, if in case you don't, im a machanic, and a few of my buddies race late model dirt cars. These things are built with one purpous only, to go realy f***ing fast, and they, running on 110, and even the boys on alcohal, are not pushing out as many horses as this kid claims to have in his street rod. (i pushed the last perioud realy hard to end my statement with confidence)

yea right. No way

Right. There's no way a 350 could do that. It would have to be at least a 358 to get that kind of power level, N/A.

NASCAR crews have to add 8 cubes to make that kind of power with no blower, no Viagra bottle, no whining turbo, and on race gasoline instead of top fuel. They routinely make 650 BHP with 358s through four 7/8" bores (restrictor plate), and over 750 with no plate. If they don't make that, they might as well not even load the car in the trailer.

They still have class limitations, so they are not allowed to go "all out".

Yeah, a guy with no lift limits, no head limits, no fuel limits, etcetera, probably couldn't find another 50 HP in the heads and valve train. No way. ;)

Whatever you say...

800 at the wheels? Now THAT I doubt. The original post didn't specifty that. 800 BHP is very possible N/A, given the right builder. On pump gas? I doubt that, too.

Then again, I've been wrong plenty of times before.

I dont think you are this time though ......

except for the 8 cubic inches to make the power .. they would drop maybe 16- 20 HP on a 350 cid ... 358 cid is just the max limit.

ok I talked to another person and I guess this 80 malibu has a ptm 350 raceblock and hes putting down 700whp on pump gas. He also said the motor alone cost $9k but I went on the ptm site and short blocks are less then $2k and heads are less than $1k and the smallest motor they build is a 355.

a 355 is simply a sbc 350 bored (i beleved) .030'' oversize. and 700 on pump gas is stretchen it for me

750 at the crank and 700 at the wheels, thats only a 6% drive train loss. To me that seems very low considering its an auto, but then again I'm used to the 20%+ awd drivetrain loss so I guess it may be possible.

what is a " ptm raceblock " ? Do they cast / machine their own blocks ... like a Dart, World or GM Bowtie ?

There is no way he purchased an 800 HP NA 350 for 9,000$ Your talking NASCAR HP on a Bracket Racers price tag.

And if this 350 made anywhere near 800 HP .. it wouldnt be streetable.

Does this kid have any idea on the suspension changes it would take to hook up that kind of power ? The stock Malibu stuff wont come close to getting it to plant that kind of power.

So bottom line is your being fed a line of BS period.

WHY dont you just sorta, you know, say that maybe if you could look under his hood, you will race him... then when he really only has the V6 that it came with, you can blow him off the road. either that, or he really DOES have the 800 horses he claims, and when you try to race him, all he can do is sit there and spin his tires since all he has is 8" slicks and probly an open diff, and the archaeic rwd, solid axle setup, vs. your awd talon. it'll be fun either way.

IF he claims he drives it on the street, he's full of SHIT. An 800 hp small block is VERY attainable, but it will be unstreetable, especially in a 3600 lb car with an automatic.

yeah a 350 with no help that uses street legal parts probably cant make any more than 600 at the CRANK... theres likely a 20 percent or more power loss thru the drivetrain as well... all i know is i will be happy with the 440 horse and 450 lb.ft. my 350 will be putting out and still be able to drive on the street, sortof lol...

by the way, if you go to gm performance parts website, they sell a 572 BIG BLOCK that only makes 720 horsepower in its best version (lol i sed only 720) and that is race only... and its a friggin 572 big block, not a 350 bored to 355 small block... basically, the most power you can get from pump gas on a 350 is probably 500hp-ish at the crank with very bad low end power as a compromise
