Stupid annoying question,SBC Vortec related.

flattie, take a deep breath, relax, ahhhh.

Jeggs, # 555-513002 SBC Votec $119.99

 

I've read the posts a couple of times and don't see where anyone has posted the casting number of a good stock head to look for on one of these engines. I'm planning to go to the junk yard this week to look for a good 350. I understand from posts here that the 906 head isn't a good choice....what is ? Thanks, John

 

If you are looking for a decent set of none Vortec heads for a mild small block, see if you can find a set of #416 305 H.O. heads. They have the accessory holes for newer Alt, PS and even AC if you chose. They also have the same intake bolt pattern as the older SBC engines. That lets you use vintage intakes. Good luck.


You can find them on 82-85 Camaros/firebirds/trans ams or 83-85 Monte Carlo SS

 

Pretty much what I was thinking...

 

There are tons of information about these heads on the web. Some of it isn't correct.
The 061 heads are not any better than the 906.

Read more about it here:

And this is backed up by several other atricles on the web, too. Do a google search for "Vortec 906 vs 062".

Fitting an intake to the Vortec heads is more than getting the bolt pattern to line up. The Vortec ports are higher than the ports on other small block heads. A non Vortec intake will not line up. This will kill the flow and cause leaks.

Some intakes are made to fit both pre and after '87 heads, but Vortec heads are a totaly different story.

 

The Hollet RED pump is generally a good one for your app, flattie, no regulator usually needed to be used with the Holley carb. The Carter STREET and SUPER STREET are also good choices and neither generally require a regulator with the pump.

The Holley can easily be rebuilt which is a nice feature.

If you need a regulator down the road, the Holley, 12-803 is only $28 +/-, and will handle everything you need, TR

Jeggs, Summit even Speedway Motors has the above mentioned part #'s.

 

I've heard of carb flooding problems when using electic fuel pumps that are supposed to not require a regulator.
I choosed to include a regulator in my fuel system that includes a Carter Super Street fuel pump.
Haven't tested it yet, as the car ain't ready.

 

I am running a '99 Vortec 350 in my '40 pickup. I used an Edelbrock manifold specific to the engine w/a Carter 625 CFM carb and a Carter elec. fuel pump w/a regulator. Seems like a good combination.

 

here is a good source of info regarding Vortec heads and the myth about 906 castings vs 062 castings

Using a byp*** style regulator and return it to the tank....will help with this issue

 

Looking pretty good FLattie, I like the color. I see you picked a good solid simple combo for your intake and carb. We need a video when ya get it running.

 

Are you wanting to run V belt or serpentine belts?

 

Do you have the right pulley for the alternator?

 

Agreed. My machine shop actually recommended the 906's.

 

I am battling the same alternator issue. Where did you get that offset bracket that you mounted the bottom bolt of the alternator to? I haven't seen that around.

Can I find that in a junkyard?

 

My PS pump is just as close. My alternator is mounted high also, but I fabbed the lower mount and I'm not sure if I'm happy with it yet. We'll see if it holds up!

 

I don't have my car at the house right now, but I will snap a shot when I get back to it in a few days.

If your flywheel and torque converter don't match up you are using the wrong size. I tried using a 283 TC and it wouldn't match up on the 327 flywheel. I'm ***uming that is the issue. Don't re-drill it!

 

Bttt. Im doing the same head swap on an early 350 for my '56 Bel Air using a 4l60 and a 3:50 gear. It's a driver not a racer. The carb is a 1406 'cause I had one and a MSD hei and coil (no box) using a vacuum advance and changing the advance curve so it's all in by 2500. Comp. Cam XE 262 h .and a small upgrade on the valve springs .

 

so if i pull a stock vortec 350 form a 96 and up truck and just add aperformer rpm air gap intake and a holley 670 carb it will make 425hp without any other parts like cam or anything? so just stock block plus intake and carb make 425hp? this is exactly the hp range i am aiming for.

 

G'day all,

Just got a core 96 Tahoe 350 engine back at work today. It ran but had developed a light tick. I can get the long block vortec core for $410 including the transporting case. Would this be a good investment?

V8nova, you must have missed this part.
11:1 pistons
Performer RPM heads
Up graded valve springs
XR 294 cam
Scorpion rockers
ARP fasteners

 

i must have read it the other way around like it had 425 in stock forum. sorry bout that. All those parts you listed are all very expensive are there any cheaper alternatives? I dont think the rpm heads are needed the vortecs should be fine from what i have read. not sure that cam is very expensive is there a cheaper alternative?

 

If this is a low mileage block and you are just using the heads and accessories I'd say it was good deal.
