Maximum HP/TQ on stock F4TE 351w block?

Maximum HP/TQ on stock 351w block?

Stock internals... Cast pistons / forged rods / forged crank.
Whats the most HP I can make before I have to start worrying?
Im afraid to throw Nitrous at my setup fearing its more HP than the engine can handle. I am using the combo in my sig..
btw, the casting # is F4TE its a 94-96 roller 351w

It'll take a lot more than a stock 5.0 block and they start to split around the 600 hp threshold. Probably 700-800 hp.

As a point of refference the FRPP 392 made 552 crank hp with a stock block and AFR heads.

 

[samuraichamploo]

Yeah, but didnt that have forged pistons? Considering the block I have has cast pistons, I would assume the most HP it could handle to be right around 500FWHP

ttt

 

[samuraichamploo]

anyone? please..

 

[samuraichamploo]

cmon...

I would say a cast piston 351 is more or less uncharted territory in a performance application.

 

[samuraichamploo]

ttt I need #'s

 

[samuraichamploo]

cmon you guys, give me a number...
this is just a roller 351,

A little impatient arent we? Why dont you juice it, blow it, and find out. Or God forbid do some research.

 

[samuraichamploo]

impatient? this has been over a day.
If you dont know the answer, Which Im sure you dont know the answer for many things.. Dont reply.
If anyone knows the answer please do however.

don't worry about spraying it i had a friend with a cast piston 377 putting a 250 shot on it, it went way in the 10's on the spray ,just make sure you have good fuel in it and back your timing off . cast pistons aren't that bad.

 

[SmockDoiley]

The block and rotating assembly can handle most anything you throw at it except for those cast pistons. I dont care whos "buddy" did what with cast pistons. NA below 10.25 comp ratio and you should be fine but once you start putting a power adder on pistons or raising the comp too high then you start breaking things. I would say she could take a 75 shot with plenty of fuel but thats the most I would do. Lose the pistons and go to forged and the engine could handle 700+.

 

[samuraichamploo]

So you think im close to my limit with the mods i already have?

I don't get you Saltymaz... Not long ago you claimed you had Upgraded Your So Called new "Crate Engine" (Look's Like An Old used Motor in your My Garage Pics) with Forged Piston's and now it look's like you actually have Cast Piston's. You said above it has "Stock Internals" Well that mean's you have cast Crank & Rods as well, not forged. I'm calling BS on you since your story is alway's changing, your combo is alway's changing and half the time you don't know what your talking about. Not only that but look at this thread for instence. Your the most impatient guy I've ever seen. Enough with the "Cmon, Cmon" and the "TTT" and the Bumps. Jeez. 65'ShelbyClone was trying to help you and give you his opinion and then you go and say a comment like that???
Your going to find out soon what it's like to not get any respect or takin seriously on Stangnet with all your BS.

Why do different people ask this same question every few days? I'm not trying to flame anyone here, but it seriously gets covered every time you turn around. Must be people are affraid to do a little research.

This is not a very good question.
With cast pistons, it will take as much power as you can throw at it if you dont detonate. Detonate and its over.
