I have the edelbrock 1405 carb and the hurricane intake manifold the bolts dont align is there a special adaptor I can buy for it?

 

call me crazy, but why are you running an edelbrock 600cfm carb on a single plane intake? Sounds like you have some mismatched parts.

 

What carb should I run?

 

Need more info, what size engine, cam, heads, etc.

 

The better question might be what manifold should I run.

 

Its a 350 not sure what the cam is right now I got the hurricane intake manifold for the vortec heads and I got the heads off of a 97 suburban I got offered a holley 750 cfm but it has no choke on it would that dobthe job

 

A 750 would probably make it worse.

Is your manifold square bore or spread?

Can you take a picture?

The problem is your items need to match the heads and cam to the carb and manifold. Sounds like you are not matching properly. The hurricane manifold is single plane and designed for a 3-7000 RPM powerband. How fast are you planning on spinning your SBC?

You need to know what cam you have. Careful vortec heads cannot handle much lift.

Sounds like you need to sit down and read a lot before you install these parts.

You probably want a typhoon, crosswinds or cyclone manifold.

 

I believe it's the stock cam the heads and intake match up theyre the vortec heads and the intake i cant put a pic unless im on the computer but its the hurricane ones from ebay I believe I just cant get the carb to fit theyre both square bore but the carb holes are 1/2off from alignment

 

Don't go 750, don't use the hurricane intake, do research and post pictures.

When I say match I dont mean physically match I mean match for air flow, and power band.

Sounds like you have a spread bore manifold.

 

What do you suggest for a good upper motor build? I do want performance along with reliability

 

Anything can be reliable as long as you spend the money right. Your question is vague.

What do you consider performance?
200hp, 300hp 400hp?

How fast do you want to spin the engine 5000, 6000 RPM?

Are you going to change the cam?

Roller or flat tappet?

Are you getting the heads machined?

Whats your budget?

All the parts have to work together to make power. An intake designed for 3000 to 7000 RPM will not work well on vortec heads and a cam that runs out of power at 5000.

 

Yeah im doing the cam I just have no clue which one I should get the heads are rebuilt but stock bore I dont think in going to machine them and im looking for 400 hp

 

I knew something was out of whack!

That is totally the wrong intake! It's not even close to what you should use.
Get a performer rpm or it seems like you are into buying the Chinese copies so get the cyclone plus or the crosswind. Personally though, for a few more dollars you can get the edelbrock and keep the money in this country.

 

is the block from the 97 also?

 

Put down the tools and start reading.

Get on google read about vortec heads, max lift and cam selection.

Learn what you already have, your block and the pistons inside.

Set a budget and research.

Don't randomly buy stuff on ebay without previous research.

It will take a lot of effort and very well matched parts to make your goal. it will be even harder without machining the heads.

 

Dual plane manifold like an Edelbrock Performer RPM or similar style from another brand are great for most street applications. The stock Vortec heads and cam will not work properly with a single plane manifold.

I agree. You will be very disappointed with your results if you just slap stuff together that don't match the capabilities of each component. Example, high lift cam (.520) on heads that don't flow above 0.480 lift (not saying that this is your situation, just an example)

Stock Vortec heads can't handle big lifts without modifications. Typical consensus is approximately 0.470 max lift for a "906" head but this can be more or less depending on the head part number. Fast Burn Aluminum heads can handle 0.500" lift which is a Vortec bolt pattern as well.

 

What build do you guys suggest with my all stock 350 right now starting from scratch using bolt ons under $1500 including used or new parts

 

You didn't answer the question.

Basically we need to know if it is a roller cam or not. So what year and car is the shortblock from?
