how much can stock internals take?

EscortSportage · June 8th, 2009, 02:51 AM

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?

dont use them in a aftermarket block...save and get a stroker kit...thats easy power...each cubic inch is around 1.5 horsepower

the stock internals can keep up with the stock block thats about it

The cranks are cast.

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?

lol that made me giggle alittle ill admit

smartest thing to do is leave the stock block alone... boost it, spray it w/e until it blows..

in the mean time build another engine with better aftermarket stuff.

87-92 had forged pistons. The stock rotating assembly can handle more horsepower than the stock block.

89Domindart · June 8th, 2009, 09:28 PM

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.

i just blew a stock block motor. it was making 567 rwhp, not sure how much at the flywheel. it stayed together for a while but it was really just a matter of time

Do you think it was because the block just gave in on its own or was there something else involved that might have helped? What rpm did you typically take it too and was that NA? Just interested.

White Thunder · June 8th, 2009, 10:36 PM

The 93s have hyper pistons. I can't spell it dammit LOL damn iPhone

superbean · June 9th, 2009, 01:18 AM

people seem to bash hypereutetic pistons, but they are a hella lot stronger than cast pistons.

89Domindart · June 9th, 2009, 02:32 AM

I love forged pistons, yes I love forged pistons. Im a big kid and I love it.

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.
