INFO: future 350 alum. heads/single plane intake

The caddy heads are already being shipped and have been run. I believe from inception to production on these heads was only 6 or 7 months. Jim Burek P.A.E. ENTERPRISES

 

Stage coach- He first told me they were out of stock cause I asked for .030, but then I asked if they have any at all. If I remeber correctly he said they have 2 sets of 60 overs, and 2 of standard size. I may be wrong about how many of each sets...

 

those caddy heads look coool. i especially like the M-35 going through the mudhole in that first picture.

wouldn't mind throwing a set of al 350 heads on my GS. or maybe putting them on my 68 350 that might go into my regal.

 

Back to Rods

I believe that we are overreacting about the rod problem. How many of us have twisted or broken a connecting rod so far? Spun bearings don't count, of course.

A High perf single plane intake and better flowing and lighter ALum heads would benefit us from 3,500 RPM on up (estimate). If we shift between 6,000 and 6,500 with a peak somewhere near 450 HP, I personally don't think that we'll be blowing the "capscrew" type rods into our oil pans, or anywhere else where they don't belong!

Let's be happy that our 350's are by far, the lightest 350's ever mass produced. With an aluminum intake AND heads, it's a great G Machine combination! We'll have realitively light cars with a very good front / rear weight balance.

Re: Back to Rods

You make a valid point, BUT....who wants to stop at 'just' 450HP??:Brow:

If the GN/TR guys can get 600-700hp from a stock girdled block - just think what potential lies for us 350 fans!?!:TU: :TU:

Aluminum heads will make 700-800hp a reality - with a power adder!!:bglasses: I can easily see an ATI Procharged and intercooled 350 making that kind of power. I just don't see it happening with stock rods.

I'm sure once Jim B. sees a good following for Buick 350 parts, he'll offer billet rods at a fair price. :TU: With a serious group purchase at Pauter(or elsewhere) for the rods - I'm sure he should be able to whittle the price down to $800-$900 for a set.

Then of course....there's the girdle that we'll need!!ou:

 

ARP rod bolts

Gents:

Does anyone know if ARP rod bolts are available in both thru-bolt and capscrew? I left my early rods with the machine shop, requesting ARP rod bolts. Is an upgrade available for the capscrew variety as well? Either way, my motor will be lucky to see 350 HP with stock manifolds and the compression I have chosen. However, the later rods can be had cheaply so its somethg to think about.

TIA

 

I have ARP's in my capscrew rods. They were available back in the early 1990's (when my engine was built) at least.

 

Re: Re: Back to Rods

That's true, Scott.

It depends what we ultimately want. I don't know how similar the V6 rods are to ours, but here's a tidbit. According the the Buick Power Source Book the V6 rods, which LOOK very similar to our cap screw rods, can be coaxed into 7,500 rpm blasts.

Here is the quote: "Properly prepared production rods have been used in winning engines in road racing events of up to 500 miles and in drag racing where production hardware was mandatory. In both cases, rpm were limited to 7500."

Right now, I am not really sure how close the V6 rods are to the 350 rods. Cyl bore is similar to the V6, so the piston mass should be very close. The V6 stroke is shorter, though and the rod length looks similar. I believe that this would mean that the V6 rod sees less stress for a given application due to less rod angularity.

Dunno...

 

Re: Re: Re: Back to Rods

The v-6 rods are similar to the 350 rods, but not interchangeable. They are both made of malleable iron. Jim Burek

 

350 aluminum heads

To the 350 guys,

I spoke with Dick from Bulldog at the Norwalk meet about what they are developing for the Buicks. He said as long as the demand is good enough they will develop about anything needed for us. BUT, we have to let him know that there is a demand for these items. He wanted feedback from everyone about these parts. I would suggest we start a thread about these and other parts we want so he can get a feel for what demand is out there. I know the demand for big block parts is good enough to warrant development of the block, street/strip heads, race heads and a variety of intakes for them that they are designing and prototyping the above. He spoke of aluminum heads for 350's but said he wanted the feedback just to see what kind of demand there really is. So let's make our voice heard guys.


Steve

 

My machine shop used the V6 non-capscrew rod bolts in my 68 350 rods.

 

Demand

Steve,

I talked to Jim B. at PAE today about the heads and intake for the 350. He said he would start a list of people that had real interest in the 350 parts. I had him add me to the list for both intake and heads.

David

 

Thanks David,

We were racing a 350 last year but put a 455 in my wifes car this year primarily due to a failure but also due lack of speed parts. I would like to build a killer 350 in the future - maybe the parts will be there when I am ready.

rod bolts/girdle

( 1 ) i talked to TA a short while ago and they told me that they have the arp's for the early 350's also now - and - they are easier to set up than the new style .
( 2 ) when i was at bowling green i was looking at some turbo/v6 displays ( girdles ) , and the light bulb went on ( $ ) , since the v6 and 350 share blocks basically wouldn't the machining to come up with a 350 girdle be a natural follow-up and fairly easy ? Del

 

1 vote for alum heads and another vote for block girdle. I'm good (so far) with the TA intake. But since I've got hood clearance issues I'm not sure I could go with anything but the stock intake or the TA.

 

block girdle

i have a block girdle in the works for my 300 block

 

TTT:grin: Count me in for a set. Someone should make a sticky thread to see how many people would buy these. The block girdle looks simple enough I going to mill one out and see if I can make one work.
Ivan

 

But seriously, what good is a block girdle??? do we REALLY need a block girdle???

 

Well if we can get some heads and rods to be able to push higher HP ratings I would imagine you would. I would'nt mind having a 600 hp small block.
Ivan:Brow:

 

Does anyone NEED more power??:Brow:

I'd be willing to bet most people on this board would LIKE more power though. :grin:

If you understand what a girdle actually does for the bottom end - you'd realize virtually ALL engines can benefit from a girdle!! Even at idle...the main caps flex sideways - bleeding off precious oil pressure!! :eek2: That's bad enough on a Chevy engine, which has been blessed with good oiling....it's even worse on our Buick engines!!!:Smarty:

Girdled Buick V6's are in the 700hp range....there's no reason why we can't approach 800-900hp with a girdled 350 Buick (with billet rods and good heads)!!! :bglasses: :TU:

Some day in the not-too-distant future....I want to have an ATI Procharged and intercooled Buick 350 with aluminum heads, billet rods and of course - a girdle!!

We've all seen boosted sbc engines make 1000hp....time for a 350 Buick engine to shine!!!:beer
