what is factory safe with a stock motor and vortech anybody

[stanggt00]

to much crap going on rigth now for me to get my forged block and have it all put together the way i want so

i opted for a brand new stock long block from mmr

so as to keep this block happy and safe while i have a forged shortblock built for next year

what is the true safe zone for the 4.6l 2v stock motor ??

i heard 450rwhp is the max then i heard anything over 400 is borrowed time

i intend to use every safe thing i can find to keep the motor happy but strong for 18months


i have full exuast with lt headers
vortech sq-trim going with a 3.4pulley down from my 3.60pulley
i have a safe tune from tim very rich a/f @ 5800rpm its just around 11.3 a/f my be a little to rich

i will be having an intercooler added to the mix in may

i just want a reliable car that i can beat-up on and know its as good as if it came from the factory that way

and 12's would be nice

it all depends on who tunes it

From Tim, it's usually right around 400rwhp and no more than 10lbs of boost. That is good enough to get you deep into the 12's.

I disagree. First off, 10 lbs of boost in one stang might produce different HP numbers in another. 450WHP would be safe if you had a conservative tune, intercooler, and good tuner. I have seen these stock blocks last for YEARS with 500+ WHP. There are some people on modularfords with proof. So if you stick under 450, you'll be fine.

BTW- why did you get a stock long block from MMR? The MMR 900 shortblock is only $2800, and you could have used the stock cylinder heads.
