Ok, so i'm sending my 350 to the machine shop tomorrow.

i'm putting it in the chevelle down the road.

The plan is to bore it .030 over.

then the conundrum happens..

i was thinking about getting the 410Hp Edelbrock top-end kit.

only deal is does it actually provide close to the hp it claims?

also what kind of piston's should i get? and is it worth getting the complete rotating assembly kit from summit? or just using my current crank?

For the money, I would pick up a set of AFR 180cc heads and then call Comp for a cam recomendation. You should be able to pick up a set of AFR's for around 1200.00 and a cam for 300.00. Total would be a little more the EB's but it will make more power.

I think there's alot of combos you could get better then the edlebrock setup. Their heads are basically fastburns if i remember right. Nothing wrong with that, but their cam technology is in the 70s.

As Dave said.. some AFR's and a good matching cam you should be able to beat the edle setup. Also remember those hp #s are crank, and optimistic.

Best thing you could do for hp if you're building the bottom end is to step up to a 383 rotating assembly.

ok, alot of people have brought up the whole 383 thing.

can someone explain exactly what makes a 383 a 383? i know it starts off life as a 350.

another thing i forgot to ask was, could i not just almost duplicate the kit by finding a set of heads on craigslist with similar specs?

i was reading a book about how to match up cam's to heads, and all the tech stuff and at the end they had a dyno motor that was basically what i was looking for, a 355, had about 420hp.

basically i want to build this motor for around $2500, i use that minus machine work.

but i want to pull somewhere around 330-400hp at the rear wheels.

383 is just a 0.030 bored 350 block with a different crank and pistons.

No way will 420 flywheel hp come out to 400 rwhp.. you have to subtract 15-20%. Is this an automatic car? Th350's use 35-40hp.. th400s up to 65hp.. thats just to run the automatic!

The extra cubes of the stroker will make it easier to meet your goal, but the best place to spend your money is on the heads. Get great quality heads. If you can afford to, don't skimp here. AFR's are a great head.

After that is the camshaft, but pretty much any quality cam will be close in price to any other. You just have to pick the right specs.

383= 350 block with a 400 crank gound to fit
or so i've been told and it looks like i got beat to the punch here lol

['92 camaro boss]

see the 400 crank was all my friend said too.

it's a th350 in it now, looking to swap a 4 speed.

my biggest deal (sick of reading so if someone can give me the bare bones info) is how do you tell what cam is optimal for a set of heads?

are camel hump heads worth a dang?

[chevymad]

Camelhumps suck compared to most any modern head. You want something made in the last 10 years. Even truck heads from the last 15 years outdo the old camelhumps.

Camshaft depends on alot more then just the heads. You'll need to know what transmission you are going to use, what rear end gears, the weight of the car, planned use of the vehicle, if auto you'll need a stall convertor to match the cam. The camshaft determines what rpm range your motor will make power. It determines if you make more tq or more hp. Big heavy car with 3:1 gears.. You'll want small heads and camshaft. Running 4:11s, a light car, and a big stall.. then you can use big heads and cam and make lots of hp. Do things the wrong way and you'll end up with a turd of a vehicle.

Street vehicle.. i'd run a 3.42-3.73 gear, at least 2500 stall or manual, 180-200cc head.. the larger on a 383, smaller on 350. Camshaft something real close to 280 advertised duration. Preferably a newer type grind like either a Comp XE or Lunati voodoo. And a roller if theres money for it.

If you want a cheap, but quality cam, Delta cams has them for a very good price. Based in Tacoma, too.

For the 2.8-3.4 it's $55 + $10 core charge for a cam. The V8 I'm not sure about price. A grind they will make specific to your application.
