help getting 400-450 hp

[drewfever1020]

ok i have already pulled my engine out and about to start braking it down.
i want to get atleast 400-450 hp on this engine.
some guy told me i should get some vortec heads and that they would be good stock?
i have an 86 block 350 of course! what do u guys i should get?
im gonna need help on a setup on this engine. thanks!

[stich626]

vortecs will not get you there.. maybe flywheel gross hp..

I'd look ad dart/afr/brodix
450 out of a n/a 350 is a tempermental beast..
you sure you can live with a set up like that

[nomrlz]

an honest 400hp at the crank will even take decent heads if you keep streetable compression.

[drewfever1020]

what heads u guys think i should go with?
i want to drive my truck around and when someone pulls up next to i want the power i need to beat them

[nomrlz]

depends on budget. edelbrock performer rpm heads are decent street heads. i've seen lots of em used for $500-700 and they are legit 400hp. afr 185's are a better but then again will cost more. i would stay under 10.5:1 for premium fuel to be safe. people have run higher but cam selection becomes very important. also if you get some "bad gas" it could get ugly

[drewfever1020]

so your saying 400hp would not take unleaded gas only premium?
what kind of pistons should i go with?
my block is 40 over

[drewfever1020]

will the stock crank shaft work with a kit around 400-500 hp?
what kind of pistons you guys think i should go with not to expensive tho?

[57sailplane]

you can do all you want up top and i dont understand why everyone always thinks in that direction. but i personaly would run the heads you have and put a 3.75 inch crank in it with corosponding parts and a good cam. you can always build the top later. It is usally the best way to go for the street. like most have said on here a 350 pushing 400hp is going to be a beast... but in my opinion a mild build on a 383 will get you 400 ponys no problem...

No subsitute for inches

[drewfever1020]

this is what kind of crank shaft i got

10147898

ok iv been looking allday at casting numbers trying to find it!
this is my engine num 10243880

on this site it says its a 95-00 years http://www.rapidomarine.com/default....sting_id_.aspx
i always thought my block was an 86 block i always had carburated.
arnt 95-00 fuel injected?
im congused someone plz help

[Captainfab]

Yes the '95-00 350's were all fuel injected. But that doesn't mean you can't put a carburetor on it. Your block will have a date code on it. It will be located on the bellhousing flange just over towards the passenger side from where you found the 10243880.

That's the same casting number I used on the last 350 I built. Mine came out of a '98 2500. It should be similar to mine. One piece rear main seal, roller cam, windage tray, powdered metal rods, 4 bolt main (some are 2 bolt).

Should be a great 350 to start with. Those PM rods are good.

[drewfever1020]

dang and i always thought it was an 68 haha
ok guys but asking for a setup u guys would go with
like wich pistons?
cam?
heads? or same heads i have?
stock crank shaft?

[Super73]

Keep in mind, when you go with a longer stroke crank, you probably need to go with a new rod and piston as well to make everything work. But if you are going to do it, do it right. Make it stronger than your intended usage.

& as you step up in demand for air, (stroke, rpm or cubic inches) you need to revisit cam, heads, intake carb, exhaust..... your motor is a 'combination' of parts that can work together, and compliment each other, , or cost power, $'s and headaches.
I'd suggest you settle on a 'plan' and work forward towards that end.

exactly! dont go out and buy alot of amazing parts because of great reviews... if ya did that ya sure you have amazing parts but if they dont mesh well your not gonna get anywhere. get a set of heads that breath well for sure and get a real plan going then go out and do it. if you could build a good mild 383 roller motor that would be a stout setup. in ontario comp cams sells a full kit on ebay for 1000$ heres the link

and if you get impatient get a strong crank throw it in and shoot it with a 200hp shot and prey she doesnt pop hahaha. but really man good luck well worth it to do properly. i was at 410hp before my roller build and even with the 410 it is a riot to see peoples jaws drop when you eat em ! special 5.0 stangs and any ricer out there :P haha

[drewfever1020]

ok so lets staart with the heads
u guys throw some at me?

if you have the money i sware by brodix and AFR both are great! but if your short on $$$ you could always take your heads out take em to a machine or motorshop and have them port them out, polish em and have them set up for bigger valves

[nomrlz]

the easiest way to help would be give us a budget goal. then let people help build a combo around that. you have to be honest/realistic what the engines use will be. then work from those points.

[drewfever1020]

i knw exactly what ur saying but i need help on how to combine what i need.
like the cam and the heads and wich valves u knw everything i need to build it like i said im a rookie

[C20-67_N_MO]

Oh I like that one.... a LOT!

They dyno test and match their components and you know they play well with each other! And the Edelbrock Vortec Performer RPM Air Gap should flow very well.

If I had the means I would do it.

So my vote would be to yes on this combo.

But I did find this for your inspection.
