how much can stock internals take?

i know that the 89 5.0 had forged bottom end (crank/rods/pistons) but how strong are they, what if i took them to a machine shop and had them balanced. And get the rods shoppened, then put the stock internals into an aftermarket block. How far could you take the stock internals?

That is one of the dumbest things I've ever heard. Why would you spend $2000 on an aftermarket block and then put used, 100,000 mile stock internals in it?

WTF...he thought he knew it too? didnt even hesitate to ask! haha...might as well buy a 351w for alot less money...and get some aftermarket internals..

My 89 took NOS pretty liberally. I dont know, I had nos open on the car for a good 10 secs once I think LOL . Maybe not quite 10 secs, but I was going fast. The car took it and runs beautifully now. BEAUTIFULLY! Actually, I want to check compression soon, just to see.

The biggest problem with hyperuCRAPtics is their expansion rate. They take a completely different ring gaps (much larger) because of this. Hypers have been know to rip the tops off of pistons when there is not enough ring gap. They have there place but for anything above mild performance forged is the way to go.

so i want to shoot for 350ish i shouldn't have any concerns with stock internals and bottom end, i romp on it a lot how much can my driveline and tranny handle thats what im more worried about

... ok where do i start, those hypereutectic piston shatter like glass when you have detonation and running more power... second i was thinking of using the stock internals to save money, and i think with a good tune and a good balance they can handle alot more than you think, my friends father and his 64 mustang, he used the stock internals and that was with a 289 (carbed) and he never had any problems. and third i dont want to stroke the engine, ive been stuck on keeping it a 302. itll be safer to rev higher and i like the concept of beating the guys with big engines with my lil baby 302...

Your logic is majorly flawed. Good tune and good balance or not, the stock internals aren't going to need an aftermarket block. You aren't going to make the stock cast crank, rods and pistons any stronger. If you want to save money then by using the stock rotating assembly then you surely don't have enough money to break it and don't need an aftermarket block.

Comparing any of this to your friend's uncle's cousin's boyfriend's 289 is not even worth typing because its not an apples to apples comparison. I'd venture to say that 289 didn't make any substantial amounts of horsepower.

How do you figure it will be safer to rev a stock rotating assembly higher than any other engine? I'll guarantee my big, heavy 425 is safer at 8000 rpm then any used high mileage parts, stock rotating assembly 302. Furthermore, you won't come near anything of mine with your "lil baby 302", much less beat me....

Put the magazines down.

ok forgot to mention my engine has 2015 miles on it... uh and second i beg to differ... (eventually) im going to turbo my lil 302 and i think i will come close to your 425ci engine, no dont get me wrong it seems like your stang is more setup for drag, so you running 9's i prolly wont come close to that, but on the street and overall performance... i think a boosted 302 will take a Big Block or Small Block with lots of cubes...
 
#29 ·
look i know that im no expert but i do know alot, my point im trying to get across is that now a days it doesnt matter the cubes, i understand its easier to make power n torque with bigger engines, but im watching turbo eclipses DESTROYING Big block chevys, left and right...hmmmm turbo anyone ? i understand its a different playing ground with the 4 cyclinders but the way i look at it is, the 302 block was designed for 302ci, so i tend to think that the most relieable setup is 302 (built) thats one reason why i dont want to stroke it, but i dont plan in buying a dart 2 iron block and aftermarket internals,but i just wondered how far can someone take the stock interanals... and its always funner beating people with the big engines, when ur running something either less powerful or smaller...

you are talking about cutting corners by using stock internals and going turbo all in the same thread. this doesn't add up. for one if you could or would spend the money to go turbo, a decent short block shouldn't even be an issue. secondly, if you are planning on going turbo with the stock short block you are still not gonna make enough power to compete with something like Darrell's car because the block won't handle it much less the rotating assembly

It seems every thread you create has the same flow. If you already have your mind made up and "know" the answer and "know" what you want, why even ask for advice and then argue about it? If you want to do something a certain way, do it and come back with the results good or bad.

Oh, and I think we already beat that small cu in myth to death in a different thread you created a while ago where you brought up a friends 2.0l Escort that runs 12's or has 300HP or something like that.

im not arguing, so running stock internals is a waste of time, got it, look im just trying to figure out as much as i can before i go and buy or do something, my turbo setup is gonna be on a different engine i want to build from ground up, trick flow top end stuff, dart 2 iron block, aftermarket froged internals, etc etc etc

my factory stuff that im using right now ill just hit it with a 100 shot of NOS, and bolt ons... its gonna be nasty on the street, and im looking into running 12's on the track

but im not building this car for drag only, i want it to handle as well , so with my latest research and discussion im thinking of throwing a panhard bar in the rear and sway bars to tighten it up, plus the tokico struts and coilovers in front with eibach springs in rear.

but here is my thing i cant get over, lots of guys with foxbodys love doing engine swaps and stroker kits...but you look at the new stangs (modular) 4.6L even smaller running super chargers and turbos making ungodly horsepower with a smaller engine than the 5.0's and those newer stangs are heavier than our fox's and they are still competing street and track,

why spend money twice? just hold off on the stock build and put the money towards the Dart build

procharged 347 said one example... a supra a very NASTY car v6... umm how bout you go youtube videos...look man ive seen civics beat vipers...like this is nothing new, my friends dad with his conquest TSI used to beat every stang around on the street with a 2.6L 4 cyclinder, i really trying to find out y people just drop huge engine in there cars and get like 5 mpg and still lose to smaller engines...(the way ur talking it should never happen) but it does

BEcause its more than just how many cubes u have, power to weight ratio/ traction/what type of drivetrain FWD/AWD/RWD there are alot of things that play into it, the first time my buddy and his escort gt ran into the 12's he beat a 5.0 LX youtube

therieldeal thats his account name and or turbo escort, he is trying to get into the 11's this summer, and this is on Drag Radials..i keep telling him to run fat slicks in the front and skinnies in the rear

1100hp Supra doesn't mean anything. We don't race dynos. If I had a nickel for every 1000+ hp Supra that I seen that couldn't run a single digit ET to save its ass, I'd be a millionaire. There is an old joke about Supras. What does a 500hp Supra have in Common with a 1000hp Supra? 12 second time slips....

Btw, Supras have inline 6 cylinders not V6s..... :rolleyes: Furthermore, I don't care what Procharged 347 posted and no I'm not going to you tube to do research for you. You shot your mouth off and I asked you to back up the bullshit that was spewing from your mouth. I have yet to see you post any of these videos that must be all over the internet if you are saying "im watching turbo eclipses DESTROYING Big block chevys, left and right". Don't post any lopsided bullshit either like a gutted 1500lb race car Eclipse or Talon racing a street Malibu with a BBC. Make an apples to apples comparison. Full blown race car to full blown race car or street car to street car. It is still going to be lopsided either way because you are comparing a turbo car to naturally apsirated cars. If you multiply the cubic inches it is going to make more power, that is the part you aren't understanding. An engine is an air pump and nothing more. Take that same turbo engine and double the size and increase the turbo size accordingly and you are going to make more horsepower.

I never said a smaller engine can't win. Smaller engines win all the time. I used to beat up BBCs with my black notchback on a regular basis, even power adder big block cars. The car is far more important than the engine. An efficient working chassis goes along way. Too many people focus on the horsepower and not the chassis. The entire car needs to work, not just the engine. That is why you see some people running 12.50s with heads/cam/intake 5 liter Mustangs and others run 11.50s.

While you are at it, show me where anybody is "droping in a huge engine in there cars and get like 5 mpg and still lose to smaller engines"? You are way out in left field with alot of your statements. Even my black notchback did better than 5mpg and it ran 9.30s. And what does it matter if its a race car?
