remember that 819 was a hail mary run on race gas and some good tuners behind it on a dyno.
aim for mid 400's for a reliable DD/track car

^^^ what he said.
pretty much up to 450 you're good on the 4.6L if you don't go crazy with revs above the redline, anything above 500 is generally considered running on borrowed time.

It may never have a 1/4 time, it was built for standing mile trap speed (should see WOT into 6th). Will probably do some road course on reduced boost also.

On the overlap cams, I would think that the fact that the exhaust and intake are open would also limit the positive pressure in the cylinder.

Your mileage may vary, but the point is, it's all in the tune.

great thread above and this thread is old!....

danzcool....yours maybe an exception but you prove that tuning means everything...

http://www.alternativeauto.com/Lidios_Rant.html

good article and my stang made 465RWHP with a safe tune on 93 octane with a max of 19 deg timing, 60# inj, and later added GT500 dual fuel pumps with about 11psi boost. She is still running strong today on the stock block with stock weak powdered rods etc...remember if one thing fails in the whole equation the motor can go boom!

I want the frpp intake manifold, hot rod cams, and frpp stage 1 heads. Beyond that I don't know what the stock block can handle. Any pointers would be appreciated. Thanks in advance!
450 to the wheels is the general census for the stock bottom end. Anything higher than that and you're on borrowed time. A simple search should pull this up for you.

Ford apparently feels that 6200 rpm is a safe enough limit for occasionally encountering it. This is most likely a fatigue limit, where Ford would have a design basis number of rev limit occurrences and engine revolutions per rev limit incident in mind.


The failure mode for the rods is tensile, but the reason that tension is developed in the rod is because the piston is undergoing tremendous negative (downward in the cylinder) acceleration as it passes through TDC. Meaning that although the piston only weighs about one pound, at 6200 rpm (and about 2500 g's) the rod thinks it weighs well over a ton.

Nothing that you do with a tune can improve the mechanical strength of the con rods or improve their fatigue life.

Well my plans for the future include a new top end. No boost. My tuner seems to think I can get close to 400 rwhp with the new top end. Think my bottom end will survive with a little track time? ( stock revs adheared to?)

at stock revs, no problem at all.
