Anyone have a link or any info on Potter heads? Where to buy, specs, etc,.... Or even an address or ph#?

This deffinately are the answer to our problem with these 60*V6 motors. Those haeds have a much higher and better intake port angle for much better flow. I can make my own intake manifold to work with them.

kretos

that is one seriously nice v6

vsixtoy

Ladies and gentlemen, thats a 163ci (or 2.5L) 60*V6 that is pumping out 349 hp naturally asperated! Thes friggin motors can rock if given the right head flow.

Wow, nice motor; but I'm sure that was a ton of coin. Imagine those stacks pointing thru one of our hoods?

vsixtoy

If they can get 350hp out of a 2.5L with those heads, we should easily get 300 "streetable" hp out of a 3.4 4th gen motor using the DIS ignition. It appears the injectors mount into the head intake ports, so fabbing an intake tube manifold that would fit under the hood would still be possible. The trouble might be mounting the serpentine bracketry to the heads for the belt assesories.

AM91Camaro_RS

very nice! anybody find any info on those heads yet??

AM91Camaro_RS

my dad and i were just looking at this... there are plaques in the background for racing championships in midgets...i bet this motor was built for a midget race car. my dad said that last time he was watching a midget race on tv, they were talking about running v6s in those cars.

FbodTrek

Sweet motor. I brought a good set of 3.4 heads home today off a motor with a spun rod bearing I pulled. The cam was wiped and one pushrod was slightly bent, but the valves are good. Time to do some head work if they are "capable" of producing 1.5 Hp per cubic inch with stock valves, 1.1-1.3 would be just fine for me . All I need now is some good literature on working these heads. Once they're done, the old ones will come off, and valvetrain will be swapped along with some 1.6 rollers.

I say we search high and low for theses "potter racing heads".
For porting 3.4 heads look at the chevy power manual and the stickey at the top of the V6 fourm.
I have a few pics on my car domain site as you all ready know.
Some day I want to get a pair of shat heads and cut them up so I know how thick the runner walls are. Then I will know how to port them to the max.

vsixtoy

I've been doing that for a couple of days now and nothing else on the internet.

Here's what I do have- A pesponse from Mr. Randy Wold who now owns the motor:

"Dean.......I bought this engine from a midget racer in Idaho and all I
know about it is waht I have here on these web pages:

http://community.webtv.net/cumonbaby/TwoCumonBabys

Engine description:
http://community.webtv.net/cumonbaby...Specifications

I thnk Stewart VanDyne could help you with these heads: 714 847-4417

This is the telephone number I have for him. he has done development on
the Potter Heads. I have not talked with him but he did the set for
Steve Spoor, who I purchased the engine from.

I'm having Andy Casale build me a gearbox for the boat now so as to keep
the torque higher as these little engines don't develope a lot and bog
down some in the corners on water. Also, I can swing a bigger
propeller. I am excited to get this al installed and on the water.

I hope this helps you. Also condsider the Bow Tie heads.....they are
good , too.

Best Wishes,
Randy Wold"
-------------------------

That gives us a little direction at least. Feel free anyone interested to check on these contacts, but please do let us know if you do and what is learned. Thanks, Dean

That motor is out of a midget and was purchased by the current owner from Steve Spoor. The current owner is putting it in a boat.

vsixtoy

I have already posted these facts above. Do you happen to know the owner or Steve Spoor personally? I am well aware who Steve Spoor is, I don't know him personally though.

614Streets

I have bought shaft rockers and pistons from Steve.

WOW

Gumby

This thread must give everyone a chuckle if you think about it.

Beside the usually V8 bashers saying not to build a 6.
Often people even here say not to build a 2.8 but go 3.4

but all the real power is in the 2.5?????


Were going backwards in performance. Sweeeeeeeeet.


I dare someone to ask about building a 350hp 2.5 in the tech section.

Gumby

Seriously though.

I wonder how fuel management is handled with individual intakes???

velocity stacks are the way to go. So simple in design and they work.

br()bert

Sure anyone can make alot of power with any engine with enough $ but is it realistic? Hell no.

AM91Camaro_RS

this motor was built for a race car...race cars have rules. engine size apparently is a rule in this guy's division. lets ask your question again; is it realistic? definately. if you have to run a certain size engine for racing like that, are you going to spend money on it? of course!, well, only if you want to win.

Gumby

Don't waste your breath AM91, brofart doesn't like like anything about the V6 but putting it down. His only reason to be in the forum is to put people and their ideas down.


He has that common SBC disease that rots peoples brains.
Though by now the disease in him is starving.

br()bert

Am91,I wasnt bashing, and the motor being a v6 has nothing to do with it. NO tipical do it your selfer is going to have access or the $ to build this engine. Sure its intresting to see a 60* made so powerful, but in the regular everyday do it yourselfers world its not realistic.

Even though ( im sure we all can agree on this) i wish it was.

And as far as sbc's or v8's go , I never brought any of that up. I mearly was discussing the topic at hand. If one cant restrain ones self one should possibly try another web site to spend their time on. Imho Nickjr.com should suite one well.

FbodTrek

ANYHOW...I've got a few idea's in the works. Is it feasible for a guy like me? ABSOLUTELY, all I really lack is a few grand to get it put together. Main cost for me would be pistons, connecting rods (too lazy to modify from SBC rods), machine work and some butterfly's to make the throttle assembly from. Ireally like the velocity stack idea, and aside from having 3 Webers sitting on top of my engine, I'm going to have to figure out how to manage fuel delivery. Sure, it'll probably never leave paper, but a man can dream can't he? I do have a certain goal though, I plan on hitting 14's on motor alone, not too hard I'd imagine. I plan to take many people's money at the local "spot", they can see the "2.8" under the hood that has some hedders and dumps, then they can keep thinking it's at best a high 16 second car. Then I'm going to fly by their butts and enjoy having the money to build my next Big block car

Gumby

So we need to find a way to make this mod doable for $4000 or less to make it cheaper then buying a 300hp GM crate.

Someone has to build one first to stop the nay sayers.
I'll help anyway I can.

TechSmurf

It's because you've failed to learn your own lesson, br()bert. You've been established as a basher. When you post comments like that, you're going to get responses like this, and eventually we'll start taking action against you for instigating such things.

And Gumby, don't do that again. Instead of helping fix the problem, you *are becoming* the problem. You're on probation... act like it means something or it's getting stepped up.

I highly suggest you put each other on ignore and avoid mentioning each other's name in posts again until you manage to come to some kind of peaceful understanding OUTSIDE of TGO.

Gumby

Feel free to delete or edit any of my post Tech. I am not allowed.

But as it stands the probation is super BS.
I am on it for pointing out people being an A$$.
[I never starts it or anything. Though I do respond to it when it super lame or pointed towards me or my post.]

which is maybe also acting like an a$$ but only / maybe 5% of all my post are like that and the other 95% are helpful n nice.

But those who act like an a$$ 100% of the time and free to run around this board???

br()bert

I didnt make any comment negative towards the engine being a v6 at all. One should read before they reply. It would be cool to see someone make this themselves but is it doable for only 4k?

FbodTrek

THAT particular one isn't doable for 4 grand, but a reall badarse 3.4 is! Use 10.5:1 frged aluminum pistons, supersix makes some lighter con rods (also forged), you'll need to take the heads and have some machine work done, there is a LOT of area to work with on the chambers. The only reason the compression is higher in these 3.4's is because they use the same chambers for the 2.8's BORE! You can unshroud the area around the valves or even add bigger valves (not too big though maybe 1.8I 1.5E). Get you a nice mid upper rpm grind with about .5 lift or so. ALuminum roller rockers from cranegold, get some high tensile pushrods made. Port matche the lower intake manifold, then the middle and add VsixToy's upper plenum and throttle body, VIOLA! I dunno about 300 to the wheels, but with the right head work, you could see close to 250. 250 Hp in a light car and you'll be pretty quick. Add nitrous and you're running 12's. hopefully.... You could probably doo all of this for about 3000-3500 bux depending on how much work you do yourself. You'll wanna lose the A/C and add a vac pump there, don't think the brakes will be too relibale otherwise

AM91Camaro_RS

anyways...anybody find anything on those heads yet??

TechSmurf

Now, don't get me wrong, I've seen you make some good worthy posts in the past few months.. but here's the rundown of why you're getting flak at every corner from various people. Because you've got such a dirty reputation at this point, you have to pay much closer attention to what you post and how it MAY be interpreted. ANYTHING negative from you is deemed bashing (by the public) because of how much bashing (actual) you've done in the past. You wove your own crown of thorns on this one. You pissed off just about everyone. You're going to need 3 miracles to put large-scale faith back in you on the V6 board.

And now, Gumby, here's a quick example of why you're still in the red....
Rules violation: public criticism of site policy.
Rules violation: Use of symbols to circumvent the language filter.
Rules violation: Public criticism of other members.
While I could probably point out where you started something, I don't really have the time, so we'll just pass on that. The second sentance, however, is my job, not yours, ESPECIALLY the way you do it. It's called "Report this post", not "Flame the poster".
Rules violation: use of symbols to circumvent the language filter.
Over 95% of AGood2.8's posts were helpful and nice, and some of the best and most reliable technical content on TGO. All it takes is one royal screwup to put you in the spotlight. We expect our members to follow the rules 24/7. Just because an earthquake struck last night doesn't mean looting is legal for upstanding citizens this morning. You still go to jail.
Rules violation: Use of symbols to circumvent language filter.
Rules violation: Public criticism of other members.

6 technical rules violations and a 'the rules shouldn't apply to me'.... and we're supposed to think you're rehabilitated?

This matter, however, is now in off-topic territory. Subsequent replies will be deleted. If you have further concerns, PM me.

Let's get back to the real topic... that obnoxious midget motor

614Streets

Search heavily under potter midget v6 . It has been searched hevily in the past by myself and others over at www.60degreev6.com . Bottom line they are rare. Its hard to beat boost and Iron heads for power versus dollor.

Gumby

I guess $4000 is a tad low. You really only get [ far as summit website goes] 310hp V8 for $5-6000

Course the weight savings make the 6 a tad better. Id only say $4000 for a well connected person who has Friends who do machine work or have their own shop. Also counting on a person getting lucking with having some of the parts needed plus picking up the other needed ones cheap.

I am sure those heads are $2-2500 easy. Most good aluminum heads run on that range.

Forget the full 350hp. Even 300hp would be more then enough to make a fresh Gm crate owner weep. strip the car down to 2500lbs and run a 6 speed with 3:55 gears.

85berlinetta2.8

is there a 6 speed that will mate to a 60* v6?

AM91Camaro_RS

not easily but i'm sure it can be done. it would be fun!

z28monster

iTrader: (1)

yeah if u can mate a v6 t5 to a v8 then there should be a tranny out there that will mate to the v6 some how.

vsixtoy

Its simple.
1) A Richmond six-speed (I can take a picture of one if you'd like next time I'm at the family garage. My brother has one sitting down there waiting to go into his '64 Vette roadster.) They aren't cheap.

2) a standard V8 bellhousing and clutch assembly (Not a 3rd gen T5 bellhousing, they sit the tranny cockeyed)

3) V6 to V8 adapter plate

If any of you think you can just throw rear end gears of your choice and a 6-speed, you have some things to learn still about powerbands being mated with gear ratios. You put a 6-speed behind a fairly stock 60*V6 and you'll NEED more like a 4.11 rearend. 3.55's are like droping your current tranny to about 2.73's. It all depends on what ratio gear package you have inside the 6-speed.

The "imfamous" Dean.

I would think with the adapter, and v8 bell housing, it would push the tranny back futher too correct?

Meaning, new driveshaft, new cross-member, cut hole in floor more.

devianb

I find it hard to understand how so little cubes can make that much power naturally aspirated. i wonder how much torque it developed?

vsixtoy

Power is made from compression and head flow. To run high compression and a high lift/high duration cam, you need heads that will flow at very high rpm's to feed the suction demand. Our heads have so much restriction from the intake port bend that it kills velocity flow at higher rpm's and the engine flattens out not yelding the high HP and torque curves- regardless of the cam and compression. Good heads make all the difference.

AM91Camaro_RS

i don't know for sure about the V8 bellhousing but the adapter plate is probably only 3/8" or maybe 1/2" thick. you might have to 'adjust' a few things but i don't think that it'd be that hard.

vsixtoy

Here's an example of what one of these 60*V6 motors can do with 6 speed behind it and 4.11 gears.

This is a fairly NON-exotic motor built for a fairly standard rpm range of 3600-5200 powerband. You just need about a 1600 rpm range to focus building the motor torque to. Just the thing required for these little engines. This equates to a fairly pumped up stock 3.4 Camaro engine putting out about 180hp and a peak toque @ around 3600-3800 rpms

The car would pull strongly all the way to 140mph-never getting out of the powerband ever.

1st- 32mph@5200
2nd- 32mph@3600/ 47mph@5200
3rd- 47mph@3600/ 67mph@4800
4th- 67mph@3600/ 87mph@4650
5th- 87mph@3700/ 108mph@4650
6th 108mph@3600 140mph@4650

4th to 5th only drops to 3700 rpm's because of the tranny internal gear ratio for 1.00 to .80

The car would run a low 15 sec 1/4 and yet still reach 140mph with a little V6

Edit- You'd also be able to cruise 70mph down the hwy in 5th @ 3000 rpms, or in 6th @ 2330 rpms. Great gas mileage also. Right now you guys with 5speeds are currently doing 70@2300 (same in top gear) but with 3.42's instead of 4.11's
