What do you guys think of this combo
gfdhbdhbgfd
383 with fastburn heads and miniram III. Some1 told me that would be a great combo and porting the heads would help it even more. Then someone said they heard you have to becareful porting fast burns or you can actually hurt the flow so i dunno. Would there be other heads that would be better? Or should i stick with this combo.

In a generalized manner, yeah, that isnt too bad of a combo. But you left out some important facts. Compression ratio, cam selection, etc. These play an important part in a combo. I have seen perfect engines, with a poor cam selection make 50hp less than they could. Sometimes even more, if another part is mismatched too.

I'm not a big fan of the Fastburns, i think they are way overrated. For the money there are much better heads.

Well Fastburns have 210cc runners which IMHO is way to big for the street or anything under 400cid engines.
Im talkin heads and intake

I think you need to do some research and decide what you really want to do first. How much you want to spend, where you want, power...
You keep using contridictive terms, streetable, max horspower, 11:1 compression...

Ive been research im going to spend what it takes to get 500 hp at the wheels. Why cant some1 just suggest a good head for the street and strip not too hard . Would you like to know the kind of oil im goin to run also i can get the other stuff to match later i just want heads right now that will flow really well that will be somewhat streetable.

A good head is the AFR 195.
I'm going to stop relying now because it is obvious you have no clue what you are doing.
Do some more research please. You will find you are dreaming :lala: :lala:
500RWHP, you couldn't drive it period!

umm are you kidding me you think you kno what ur talkin about. look how u replied to my previous post u had no clue. Kandied91z 383 had 500hp so look again that might of just been with a lil nitrous also. So you need to do some research i was planning of going with the fast burns and miniram III. Cam With 1.6 rockers, the specs are:
.537 / .544
230/236 @ .050
112 LSA
108 ICA
damn your killin me
.537 / .544

Now if we actually got some1 in here that knew about fast burns and if it was a good idea to port them and not ask questions that are not even needed then i would actually get some good info out of this. Look at my last post you made a ignorant remark then some one knowledgeable replied and we had alot of good info in that post.
Just forget it ill pm some1 that knows there **** i said i wanted 500hp at the wheels and i seen alot of combos with 450 that wernt really radical. So if that is imposible wow maybe im 50 hp off would a 50 shot kill anything. Is all you do is reply looking to start a flame war.

500 crank hp and 500 whp are 2 different things. I am with the others on this one. You need to look at what you are considering.
here's my "race" engine plans that i'm tossing around. The street intentions of this engine are nothing more than drive to the track and back for the most part.
Isky solid roller cam:
Lift w/ 1.5 rockers: .548"/.557"
Dur: 308/314
.050"Duration : 262/272
Lobe Center: 110
RPM Range: 3200-7500
AFR 210 heads, Isky 9965 springs, yada yada
Fully forged 400-based platform
4.11 rear gears, 3500 stall
yea, you need to reconsider your intentions. Especially if you say NA.

I'm not trying to flame you, your goals are just outrageous. If you ever get 500RWHP and hook, your entire car will break.
I'm trying to help, you because it is obvious you need it. I mean you don't even know what a good head is.
To build 500RWHP your looking at $6000+ in the motor and atleast another $4000, to make your car handle it with out breaking everything.
I know alot of people are making pretty good power, but they spend tons of money and race them.
Didnt i just say all that??? oh yeh forgot 3.27 rear end who cant change that thought you guys act like this stuff is set in stone. Wait you left out the size of the carb oh no you cant have a engine with out a carb or throttle body. Also since when dont i know what the diff between crank HP and wheel hp u must think im 16 yrs old are you kiddin me . I grew up around cars and my dad builds classics for a living and i built a few older style blocks pre 87 so i think i know what im doin somewhat.
Please just stop assuming you know me im will be running the 5 speed for now till it blows then 6 speed and im getting a cage. I also have every suspension part just about but a torque arm.

Also to get 500rwhp you will need atleast 600hp on the motor probably closer to 625 after beefing everything up to handle the power.

This isn't magic, just research what others have done, and what you really want to do. Thats all, just plan on replacing lots of broken parts.
YEs i will thanx for the reply just thought i would post for once ill have to forget about that ill get the info i need on my own. Why is it the people in the suspension section are so cool ill just talk in there.

i think you'll have to do some more searching for heads/cam to get to 500RWHP.
I wont pretend to know exactly what I'm talking about, but I've got a decent starting base I think.
This is to my understanding --
You'll need a 4-bolt main, or splayed 2 bolt mains for the block.
Forged internals because at 500HP NA that's ALOT of stress on the rotating assembly.
If you want to keep this streetable AT ALL you'll want a gear ratio in the low 3.xx's
I wont go into the suspension, brakes, chassis mods you'll have to do, you seem to know all this already.
Now I'm assuming that you'll want this to be a high-way warrior, not a stop-to-go demon (city driving).. so you'll probably want it to rev to 7000-7500RPM. Heads and throttle body to match... Fastburn wont do it, I too have heard that porting them can decrease performance if not done by a professional who knows what he's doing. No offense to Sitting Bull, but I dont think that the home-porters should do it.
Your horsepower is basically all going to revolve around your heads/cam choice. The carb, throttle body, exhaust, etc, etc will have to be hella stout and well engineered to keep it streetable and still make 500 to the wheels NA.
But if you are thinking of using nitrous, then you had better say that before you want to build the engine, you build an engine AROUND that kind of stuff, not after you built the engine.
I do have a 4 bolt block and forged rods all the good stuff. Just cause i dont know about all the heads out there or have tried them out doesnt mean i dont know how something works. You are kinda right about my setup but i was just lookin for a great head cause i havnt used many other heads then stock. I do want to kick some butt on the street when i take it out occasionally but mostly want to spank all the street cars at the track well alot of them at least

forged rods
Lots of stuff that needs to be researched so you get a combo that will work together.
AFR's do look nice! The price also looks comparable which ones would be best? They have alot of different ones. I was lookin at these 195cc Street Heads, L98 Angle Plug w/heat riser, 68cc

I'd just get one of these if you don't want to research SBC 454 Crate Motor
or one of these SBC 427 Crate Motor
The 427 make 505hp at the crank, so your still way short of your 625 crank hp goal.
Good luck

get 210s. They have better flow at lower rpms, with small loss to the 220s at higher rpms.
As for the rods, watch out how you go tossing around the term "Forged."

Here read, the do some research please, i don't know why i am doing it for you . http://www.hotrod.com/techarticles/82378/
Yes i think i do lmao you prob think the block is forged also. Anyway when they call rods forged they are usually talkin about they were reheated. Also after market rods are alot better metal.

No kidding aftermarket rods are made of better materials and designs, thats why there is an aftermarket. If stock parts were good enough why would people need to replace them?
