new engine build suggestions

ok ive got about $1500 and im currently looking for a 350 standard bore block.
ive got a 4 bolt block that is 40 over but its not going to work for what i want.

im giving some thought on strating the build of a 383 stroker.
this is going into a 1982 chevy swb th350. im looking for around
425hp to 430hp  this will be a street toy will not be a dd.
i still want to stay around 10.1 compression or less.
im looking at a set of dart heads  they are Dart 127422 at the summit site.
the cost is right around 930$ for the set.

the cam im looking into  is a lunati voodoo 489/504 the duration is 268/276.
plus ive already got a brand new 2400 stall in the box for my transmission.

are the heads a good choice  ?  
is there something maybe i could do with the block i have for this hp range?
ive not had the bore checked on it yet so i dunno if its good.

or should i lean more towards the start of the 383 stroker build.
i know  eagle makes a good kit with everthing  right around 700$.

please if anyone has ideas or suggestions let me know.
i have not bought any parts yet at all.  

Yes thats a good budget head.  Much better than I would have expected until I saw the kind of numbers they were producing out of the box on healthy small blocks.  Impressive for the money invested.

I prefer scat for the rotating components as opposed to eagle.

If it were me...  scat 9000 series cast crank and scat 6 inch I beam rods(the 4340 steel rods) with 7/16th capscrews.  It'll internal balance pretty easy and the capscrew I beam rods have more camshaft clearance than a factory 400 small block rod.

The cam is a little soft.  Id go with the next size up voodoo camsahft in a 383 with 10:1 compression.  430ish horsepower is more doable.

Id finish it off with a peformer rpm intake and a 750 carb(holley is my personal preference).

I dont know what rear gears you have but if that truck is relatively heavy and you dont have too much rear gear to work with....staying with the cam you like might be the better option.

but if its not mega heavy and you have at least a 3.73 rear gear Id go with the larger, next size up cam.

Not quite sure how youd fit this all in a 1500 dollar budget but you are on the right track concerning how you wanna do things  

oh i know i cant  build hte whole motor on 1500$.
but its a  good start i want to try an get most expensive sutff.
out of the way like the kid and the heads.  
i was going to get the performer rpm intake was my choice.
the carb choice was goign to be a 770 street avenger but it might be to big.
the next cam up requires 2800 stall convertor mine is 2400- something i fargot i think 3000.  
im still trying to locate a block right now virgin block they call it.

another question  is  the heads an cam set up with some kb pistons in that 350 i have.   i doubt ill hit 430hp but  what kinda build would that be if bore is good.
on the 40 over block i have?  

If you built this combo in a 350 platform horsepower would be similar to what it would be in a 383.  The power would just come a little later(higher rpm) and the torque curve overall wouldnt be as strong.  If you went with the smaller cam in a 350(as opposed to 383) right around 400 would be expected with the good heads.

Any reason why you cant build the 383 in the block you have?  I realize a conventional 383 uses a .030 piston, but that doesnt mean you cant use a .040 or .060 piston if your block needs more than a .030 bore to clean up.

It would just add a couple inches is all.  

+1
I'd opt for the 383 and reach that 425 horse mark, in street trim.
A bit more cam should have it.

I'm going to have the shop check my block.
I got the motor out of a 78 gmc longbed truck was totaled.
Motor was about y months old its .040 over now.
If had to go 60 will I face heat problrms?  

No, a .060" overbore will not cause heat issues.

Hi Peter,
 Howzit ging with you
 For this combo I would start off with a 700 Holley
 mechanical with progressive linkages closely matched  
skyeking

my torque convertor  is only  for 2400 stall the next step up in cams.
require a 2800 stall  would it be a bad idea  to use the 2400 stall or??  

Hi There,
   Forget the budget. It's gone with the wind
   If you play around with gearing and torque convertors.
    All the best... theUnexpected costs of a project hang
   over our heads like "The Sword of Damocles."

thats just my starting budget   to start the work towards my motor  

When it all comes down to it you have to decide what you honestly want out of it.

An honest 430 horsepower or so takes a bit of a stout combo out of a conventional small block.  It shouldnt be any slower than a mid 12 second ride with that kind of power either.  Your combo, as you initially proposed it would still run 13's in just about any car and it would dip in the 12's with the right car, gear, converter, and chassis.

If you really want that 430 horsepower, the larger cam should be a consideration, but you also have to be prepared to step up the game on the surrounding parts.

The 2400 stall speed will work.  Its just not optimal.  My suggestion is to use it since you have it but when the budget allows upgrade to a GOOD converter.  

the converter itself is way more important than many people give it credit for.  the right one can transform the way a combo performs bigtime.  

+1 thank you for the advice
I dont ever plan on running down the strip.
Just want to be a fun steet toy.
I'm still thinking of other options.
Building a 383 or what ever.
I see articles in mags on 350s.
Non stroker 400+ with good heads n such.  

Look for a 400 block and crank and do all the same stuff.then get an o/d trans a 700 or a 200r4.the 700 has a gear to launch the truck better than a 200 but in a car I would say the 200r4.with a 3.73 rear gear you will be lik'ng life.  

this truck isnt going to be a daily driver.
amd i already have a turbo 350  with a 2400 stall.
i once had a 200 4r transmission sold it  for 200$ cash.
it was a good transmission shifted good and nice rpms down the highway.
was in 84 swb behind a 305 anyway  one of thease days i wouldnt mind having a 700r4.

some more info about my 350 block it is a 4 bolt main and bored .040 right now.
the shop i use hes busy with dirt track stuff at this moment have not had a chance.
to get it to him to have it checked out  and see if the bore is good.
or  to see if it might have to go .60 on the block.

so i was even thinking  not stroking  it and getting some kb pistons.
that will have  decent compression with the heads i posted above.
the step up voodoo cam edlebrock performer rpm intake.
im not sure if a 600cfm for this build would work or not.
if not  would 670 cfm or whould i need to lean more towards 700 or 750?
if i were to use the block non stroked some good pistons n stuff.
would i be right around 415hp or so??
