so i have a 1991 rs camaro was completely stock with a 305 10 bolt and an auto recently swaped a 9 bolt with 3.27 gears in it and soon to be swaped in a t5 but im looking to build around a 500 hp engine would like a little over 500 hp so i can get close to 500 hp at the rear wheel i think i want to build a 383 caz i think i can get the most torque and hp out of it for parts i have 1.94 doubble hump heads and some where around 10 to 1 pistons not exactly sure my dad got them a while ago and dosent remember and an eledebrock preformance rpm intake any one sure how i can achive this and what parts i will have to buy get this? i need to know from carb to pan

t5 won't handle it - so better get t56 first.

FalconZ28

Definitely. A T5 can barely handle a 305. That's why the factory never out them behind the 350s. T56 all the way, don't waste your time and money on a T5.

i know my t5 wont handle it but my cars an auto i bought every thing i need to swap from auto to manual with the tranny for $300 i was going to put the t5 in drive it around with my 305 unitll winter build the motor then swap the motors and then buy a t56 or many a tko and swap it in my concerns are not really in the trany i just wanna figure out how to get 500 hp at the rear wheel

Avoid the T-5, for sure. So, you're not going efi, right? The compression of your pistons will depend on the crank and rods you use (stroke). Just make sure you use good parts, and make sure your heads are designed and built to handle a higher lift cam and the amount of airflow you want, in order to achieve your goal. Underneath the proper heads, you'll want more than 383 cubes, if you want to go naturally aspirated. If you search the forums and so some research, you can find some engine combos that make close to what you are wanting, but lots of them will be big blocks or close to it, if you are talking naturally aspirated setup. 500 to the wheels is gonna take some cubes and the right combination of heads, intake, carburator, etc. I'd figure out a way to save up at LEAST ten grand, so you can get a good rear end, tranny, stall (if you go with a built 700r4), and engine parts. It always seems to end up costing more, rather than less, especially if a guy builds a setup that works right and won't break too easily.

Figure a 17% drivetrain loss, depending on auto vs standard tranny drain, plus the accessories, etc.

To get 500hp at the wheels, your gonna need around the 600hp mark, at the flywheel.

Before we even bother starting an 8 page thread,

What is your budget?

snowboardgod869

i don't really have a budget i mean like said above 10 grand thats a little much for me but i do have some time and money to spend so far haven't even started the build yet still looking for a good 4 bolt main block or wondering how much it will cost me to turn one of my 2 bolts into a 4 bolt splayed i know i could easily put together a 400 hp engine with what i already have and not to crazy of a cam i know i can get alot of hp by just going with a really crazy roller mechanial cam some where around the 330 duration and maybe some thing like 580 lift? also thouse 1.94 double hump heads i have are shaved for more compression

snowboardgod869

and no im not going efi i already have an intake eledebrock rpm performance intake that will get some thing on it like a 800 cfm double pump holley and i didnt really wanna go big block with this build that's a lot of work trying to get that to fit and extra money

To get 500HP to the wheels using a SBC and no power adders is possible but isn't going to be cheap especially with a small engine like a 350 or 383. You're going to need a power adder such as NOS or a BBC to do it easily or use a large SBC such as a 400, 406, 434 etc.

If you look at all the prebuilt engines available, very few SBC push into the 500 flywheel HP range unless you're buying a full race engine.

From the parts you've already mentioned, an engine in the 400 flywheel HP range is more what you're going to get which means you probably won't get 400 to the wheels.

snowboardgod869

well sounds like every one thinks its gonna be way hard to get 500 to the rear wheel so how about if i get 500 out of the engine and over 400 at the rear wheel how would i be able to do that?

A simple crate engine is easier than trying to build one.

that's a nice engine but im pretty sure i can build one cheep than 5 grand considering i already have most of the parts i need to build it becides the crank rods and cam and a few other things

I would hang around the forum here for awhile and hang around the race track and meet real people who race (not some out back hicks who have "race cars" that you've never seen).

Meet real racers, see what combos they have and what times they are running. Start small. Learn as you go. Find out what works and what doesn't from other people.

Right now you're just throwing numbers out there. It's good to get a basis before you start doing stuff.

That's usually the advice I try to give anyone who comes on here asking about building big horsepower engines.

If you're really ready for 500+ horsepower to the wheels, you don't need to ask about it. Just my 2cents. Good luck bud!

Just remember, you can only pick 2:

Fast, Reliable, Cheap.

Typically when I hear about someone who wants a 500 HP street car, the first thing I ask is if they've every driven a 500 HP street car. A 300 HP car with a 200 shot of NOS is not the same as driving around with 500 HP available all the time. Most people are quite happy if they just get 350-400 to the wheels considering most factory cars barely get 200 to the wheels.

Trying to cruise with high HP and driving at low rpms in a car with highway gears to try and get better fuel economy is just asking for problems. I'm never going to say it's impossible but for most people, they don't realize just what's involved in trying to do it. Magazine articles or all those automotive TV shows just complicate things even more.

What are your goals for the vehicle? That sets a better marker as to what you should do.

Couldn't have said it better myself.

Not trying to discourage anyone, just trying to give sound advice. Trust me, it'll save you a lot of money, time and headaches in the long run.
