Iron Vs. Aluminum, the Final say!

[SappySE107]

whoa whoa whoa! come on now! you got a couple of fiero owners on here who have a little sense!

Sure we do, and they know better than to waste their time arguing over iron heads with ANYONE.

I'm just attempting to stop the spread of mis-information...

[SappySE107]

You can't. I tried, this site is proof enough of that.

What annoys me is that when searching for good Fiero engine swaps, 3x00 swaps rarely come up. I only learned about them when I found a local classified ad for a 3500. Then I started looking up how difficult of a swap it would be.

I would never have considered it if I hadn't found that ad. You'd expect Fiero.nl to have more resources for swapping them considering how easy it is. Most of what you find for "easy engine swaps" are the 3.4L RWD or 3800; 3800 requires more work and 3.4L doesn't provide much of a power increase. 3x00s can often be had for cheaper and with less mileage than the above also.

Edit: then you find more swaps where people put their iron heads on a FWD block, which makes it seem like either the FWD heads are not any good or its too much work to bother.

as much as I don't like to say it, at least the 3800 is a proven performer, the 3.4 is just a turd though.

Fiero.nl really isn't that great of a site, because it's self moderated, people offering real info frequently get boo'ed out as trolls, and that only leaves the people who think a smog 305 can put out 500 hp because their swap ran a sub 15 second pass...

Unfortunately, Fiero.nl is the first place I would think Fiero owners would go for advice. I know I did.

Edit: agreed on the 3800 being a good performer. IIRC almost all of the fastest 1/4 mile Fieros are using them

Lol, I just read your post... lol! he'll be in there to tell you your cam is to big and you can't street drive it...

[Superdave]

too bad the rear end is trashed, i'd take it out for a NRE type video and go pick up some Taco Bell or something.


If it ever warms up here i'll go pick up one from the JY and get the 4.10's installed.


edit, you called it.. haha

[ericjon262]

lol told you!

But they put down some torque.

up to 4500 rpms that is... and obviously not enough to make it over a bridge covered in "trolls"

For the record, my Franken60, used FWD genII 3.1 pistons. They were aftermarket stock replacement pistons, in a .030" overbore, but nothing special. I used the genII headgaskets as well.

If I were to do it over again, I would use the genIII pistons for a bump in SCR, and the large port genIII top end.

if you want to flow those iron heads, I'll send you a t/a performance cover for your 10 bolt with the heads if you want it.

it's also funny that you broke the 10 bolt, and the 327 that was in it before didn't...
