i was just wondering what range of hp i can expect w/out needing to replace the stock internals. i plan to rebuild my motor soon (150000mi= not good), including a mhg, but should i buy forged internals. im on a budget and my goal is 450bhp.
max bhp on stock internals?

lots of people have hit that hp number on stock internals. if your gonna rebuild, do it right. no slacking off. you only want to do it once.
I've heard of people running over 500 on stock internals, Reign Maker had a thread about cryoing stock rods or going aftermarket. alot of information was discussed about the stock rods and most people agreed they are good up to 600hp, I believe he has forged pistons also though.
hope no-one minds a link.

the stock internals can reach 500+horsepower but....it wont last forever.....rods knocks will occur since thats also a problem with our cars.....
so also start saving up for one....
if u take care of the car it might not happen.... some ppl go through rod knocks and some dont good luck with the project...

This is so old. What does horsepower limit have to do with starving a bearing of oil? How about nothing. Maybe you could say RPM, but not with our redline.
I think some people need to start doing a tear down on their "rodknock" instead of dumping in a used engine and finding out what the knock really was, like say a scored piston, broken wristpin(not real likely) spun bearing, etc.
thanks for the info. i'll have to think about it but i know this will be a while down the road, when i'm not broke.
For me 350>400 would be the max I'd push on prepped stock rods but then again I'm a bit conservative as I don't build Hand Grenades.
I always try to leave a good margin of head room.

so if you'd only take the stock piston to about 3-4 hundred, and we would take it to abotu 600, about how much hp do you think we could pull out of your current engine before we blew it?
Simply put...Our stock rods are good for more power than most 7M owners will ever be putting out anyways. They're very similar to a 2J rod. I don't even know how rod knock came up in this thread...But it has nothing to do with age or power, rather poor maintenance.
I would def. say go with forged pistons - Just because you're rebuilding it already - An extra couple hundred bucks and detonation won't be as big a deal when it happens. Blowing the mhg beats melting pistons

AJ: Mine should be good to 1K without any issues given enough Fuel and the right tune! (For me the limit would be 600 to leave the overhead I like)
I think most people (kids?) on here have this insanely high goal of HP for no reason at all.
As I always say, go take a 500 WHEEL HORSE POWER car for a "spin" and come back later.
The stock 7mgte block ( properly rebuilt of course ) can handle MORE horsepower at the WHEELS than the brand new Z06 has at the motor!!!
Just think about it......with 450whp the Zo6's performance......yeah....and dont bring up the "weight" discussion....the Z06 is only 200lbs lighter

Most kids that want 500+ don't even know how to go about it...The ones actually doing it have reasons
Or they dont have the money to begin with. Power does not come cheap, and cheap power will not last. Can I get an "AMEN"
siman said:
Depends what "cheap" is...You can run an SAFC instead of an SAFC2 and be fine...or an old profec instead of an e01....or an upgraded ct instead of a t4 turbo
but generally speaking, to get it reliable in the long run, you have to do it properly
No reason someone who's 18 even, can't make a reliable car with 500+
I'm 18 and know better than to just think I can achieve supercardome(500+hp) by just bolting on parts. I set my goals realistically and gradually mod. I'll crave more power...and slowly work up to that power the safe way. I hope to have 350-400hp eventually and be running 12's before going crazy with turbo's and huge goals. But I'm not gonna blow headgaskets and get knock for turning up the boost without the right precautions. I wish some people wouldn't just think "I want an 800hp car" and have no need for that power, or want the power by cutting corners.

very true.
the biggest question shouldnt be "how can i get 500hp", it shoudl be "can i handle, and am i an experienced enough driver to manage more than 400hp?"
yea, I'm not saying I can handle all that power, but plan to get a 7mgte(or 7mge block if I can find a cheap 7mgte block) and build it up for a finishing touch of 400-500 hp. I'm diff up for some hardcore research...
my old monte carlo ss was a 400 hp car. nice and fun. didnt like to be in it when it rained or snowed. couldnt keep it on the pavement!:evil2:
