a good motor that a lot of people forget about is the old 283 corvette motors... they're a very good high RPM motor with a short stroke.... it'll kind of remind you of the 4cyls you're used to but instead be a v8.... they're a good quick motor and lighter weight than a 350..... the availability on them is a little less though so it would be something you'll have to do some looking for..... i've had a coupla 283s and i loved them.... they're great for road racing and the such.... i used to dump mine at 6000rpms and just launch in my little nova....

nah 283 is too small, I think im kinda leaning toward big displacement and not caring as much about redline anymore. Ive always wanted a muscle car, what would be better for a light car and midrange to top end power a 383 stroker or a small block 400?

My dad always talks about his old car with a HO small block 400 and he said it was wicked fast, so ive always wanted that engine. What should I look for as far as a block or complete engine? could I build it to run up to say 6500rpm without spending a load of money? Is there a good aftermarket for these engines, I dont know if they are based on a 350 block or not

also I always see engines out of trucks, are these different engines. Can I use an engine out of truck if I build it up with different parts?

Buddy, building the engine for this car is the easy part, getting it mated to a transmisison and the axle of the Fiero is the part you should be worrying about first, then find an engine that plays nice with your tranny and axle choices and get to work!

I already have an adapter plate and kit from v8 archie. I know of people who have put 383 strokers in fieros, im not worried about that at all. I just gotta build the tranny up a little bit, supposed to handle 400+hp stock

Good, you're already one step ahead of me then =P

Which tranny are you refering to though?

People are absolutely DESTROYING 1st and 2nd gears with built 350s in Fieros with stock trannys, and some with Getrag 5spds, pretty much you gotta do something drastic, or your trans-axle has to be lady-driven...

I hear the 4sp muncie is slightly stronger than the getrag so thats what im going to run. I think people start grenading stock trannies at like 500hp

Hmm, yea, the auto is supposed to have more bojangles in it, but 500hp on stock trans-axle? Not a chance, if you go north of 250-275 ft-lbs of torque and bag on the stock tranny too much you can bet on de-toothing your gears in an awful hurry.

That trans-axle is built to withstand a 2.8L V-6 135HP Iron duke, not the sturdy supercharged L67, and NOT a torque-happy 5.7L V-8, I think the LQ1 twin-dual cam you already have is about as powerful as you can get while being able to COMPLETELY bag on car with a stock trans. You know, hard launches, clutch drops, violent shifting, drag-strip stuff.
