what are the flow numbers for those heads? might need to lower CR and bump up the cam?

head flow determines maximum possible h p

find heads that you like,ask what they flow and intake runner volume,then let us know your intentions.
The dart shps will provide over 400 hp for sure.some other heads will also do the same thing.
shp heads flow close to 200 cfm at .300 valve lift and get better

I don't know what info I need specifically but the heads are the first one on that list and I am not planning on doing anything more than being loud and fast light to light, this is just a car to fulfill a childhood dream really

fast light to light?
get a big converter and gear set with some drag radials and you will get some 0-60 times in the 4 second range with just about any v-8 F-body or something similar

If you want to build a 383?
heads,,,look at the intake flow with the valve .500 off the seat.What evet that number is,double that and that is a "guideline" number to the horse power the engine could produce.
If the engine make 1hp/cubic inch (383 horse power) that is considered a nice daily driver that is well enhanced.You can build this combo with a flat tappet hydraulic cam

to produce 1.2 horse power/cubic inch we are now tuning using premium parts.
good flow rate on the exhaust side of heads,about 75% of intake numbers
need a very good carb and intake,perhaps will have a lumpy idle,
460 horse power will need a medium roller hydraulic cam ,good headers and exhaust,750 carb

1.5 horse power per cubic inch motors ,idle rough. need very good breathing heads/manifols/carb/exhaust with moderate compression
bigger roller cam,solid roller preferred
net 570 ish horse power,,,
heads will be ported and bigger
RPM range much higher

Okay the 383 concept is no longer an idea I am sticking with the 355, the headers I have are hooker headers. I understand some of what you're saying but this is the first time I've ever looked at or dealt with heads so i don't really know how all the math works out.

Realistically I have about 3000 to spend on the engine, I already have the block pistons crank and now I just need the performance parts. So what I guess I am really asking is for the money I would spend on the edelbrock top end kit that puts out around 410hp is there anyway I can get more power with that 1900 or is that already a good deal

The kit is generic.Because you are new you should stick to generic.What I would build on a budget you might hate. Im not afraid to use a decent cam(bigger) I like double pumper carbs.Im not afraid to rev an engine.Noise doesnt bother me,I look at it as music.

you need to determine the purpose and application for you? Maybe its not horse power you need?
what kind of car? what do you want it to do?How good are you at fixing things or making adjustments?
give some details and we can all give ideas
list all the parts you now own

Okay the car is a 1981 camaro I have a performance th350 with a 2000 rpm stall. Engine wise I have the block bored to .030 and matching pistons and rods that are stock I'm assuming as there are no numbers stamped into them. I have a stock crank and the block is a 4 bolt main. As of right now that's all I have. I guess I'm ring fooled by numbers and chasing hp but I do know I want it quick and loud, my old camaro ran straight pipes to glass packs and I loved the sound but that was a stock motor. I'm pretty handy and have done engine and tranny swaps and other things I just have never built an engine which is why I didn't just buy a crate engine and put that in because I want to start to learn about it. I don't need a fast and the furious car but I also want when I really step on it then I know I'm gonna take off

OK! I had a 1980 Camaro. They are big and fat.The car needs to lose 400 pounds first.you can use the 2k converter if you build a torquey engine. If the gear ratio is 3.42 then thats 1/2 the battle,after the weight reduction.
bumper braces and door inpact braces are a good start

Okay well I have already removed the rear seats from the car and have more plans to drop weight and I already got rid of the bumper brace. Right now my concern is the engine and I can work on everything else as I go but I have about a month until I won't have the tools to put an engine together and install it myself which is why that's my first focus

Right now that is what I am tryin to figure out, I have a block and all internals minus cam and lifters so I'm trying to decide the best top end kit or parts combo to get me pretty quick on the road, right now I either plan to get the edelbrock top end kit part 2098 and it comes with a cam or a dart top end kit with no cam but is about 300 cheaper and I would need a cam that would compliment it well
