I will talk with the guy who does our heads and see who he knows who may be able to offer P&P options for the engine.Night Wolf said:yeah, I saw that a few times, but it is really expensive, I can guarantee that for $9,600 I can get an extra 100hp outta the 4.9.......
...... I was hoping this thread was about someone actually making performance parts, like headers, intake manifold etc..... Also, the 4.9 is a popular engine for swapping into Fieros, so there would be a demand.

I agree and the 4.9 have limitations based on the stroke issue and really I suggest a 4.0 l with good mods as my preference but that’s another story. The main reason for the 4.9 is the lumpy cam feel and major neck snapping torque to play hotrod with. I agree with the kit for those who are happy with a limit of around 350hp but want the umpf and wump wump wump of a torque monster.Shoehorn said:The 4.9L is a popular fiero swap.
Some people only look at displacement, and given the choice of a 4.5L or a 4.9L they think "bigger is better". This is not the case.
The 4.5L and 4.9L share the same bore size. The 4.9L just has a longer stroke, which is good for low end torque, but can't rev high.
The fiero in full factory trim weighs in at about 2500 lbs. It doesn't need any more torque. The shorter stroke and reduced rod angle of the 4.5L allows it to rev higher than the 4.9L. Considering that the mod is usually performed on a 3 speed automatic (highest torque rating, and no need to plug and redrill a flywheel.), the 4.5L is, for most, the better candidate.
Now the lunatics who like to replace tiny fiero clutches monthly, and run the weak getrag (self-disassembling) 5-speed or the Muncie 4-spd transmissions would gain more from the 4.9 because they have more gears, and don't have to shift at 7000 rpm to go fast.
My 87 GT is getting the 4.5L. I'll pass on the 5000 rpm redline. thnx.
Sorry, I have to spout off all of that every time someone mentions putting a bus engine in a sports car. Obsessive compulsive thing.
From what I've heard, the ASG engine looks like a good product.blkchrry92dvl said:I posted this in deville forum and got no response so far. The 5.0 liter conversion looks interesting; let me know what you guys think.
