Thanks alot- They were not expensive and they had several grinds- hydo/solids/auto/manual.

To Chrisarnt.....no do not mess with the rockers. They are already 1.3:1 from the factory.
You SHOULD source a set of rockers from a 1.7L and buy a set of Porsche swivel feet adjusters....and a solid spacer kit. Two of the best galve train mods you can make with a type 4.
Do your lift adjusting with camshaft selection on a type 4.....not by screwing with lifter ratio. You will have enough geometry challenges without that.....and....not that I am even sure where you can buy higher lift ratio lifters for a type 4.
Last ones I think i saw were years ago maybe by Autocraft. Ray |
OK. I'm confused: "Do not mess with rockers. " or buy a set of rocker from a porsche 1.7" ?
and swivel feet adjusters and a spacer kit.
How about the cam?
I read the discussion on the cam with the other guy, but he's putting this in a bus. I'm putting mine in a beetle. So... What say you about the cam. ? |
Your original question was......"with a cam upgrade.....comes a rocker upgrade?"......the answer to that is NO.
1. Short of astronomically priced custom rockers from someone like Pauter or Autocraft....there are no "upgrade" rockers for type 4.....and they are nit necessary. The factory stock rockers are 1.3:1 ratio.
2. Even if you you changed nothing on the engine.....even if its bone stock.....you SHOULD put a solid rocker spacer kit on the rocker shaft as it makes for less wear and more accurate geometry. Also.....the swivel feet are another "must have" for lower wear, not needing lash caps and more accurate geometry.
Before anyone can really tell you what cam would work well.....get a really good idea of what carbs, what tire size, how you are going to drive this car.....and what you need this engine to do.

Ray- what is your "most go to" cam when building a T4 for a bus? (loaded camper--14"tires 205's// 002 trans from a 73 -) _________________ some days I get up and just sit and think. Some days I just sit.

....I dont build type 4's for a bus.....at least not for about the past 15 years.....but if I was going to suggest a cam......if it was twin carbed and largely "stockish"....a web 86 is what I would use.
If one "must" use hydraulic lifters....again with carbs....the nearly equivalent is the Web 91.
If its fuel injected and mechanical lifters....primarily stock.....I would use a web 73....fairly mild but an upgrade.
An upgrade from that would be the 9590 from the type 4 store (this is an upgraded 9550 to make it run better with alcohol fuels.....and the 9550 is actually a sppit pattern version of the web 73).

Thanks for the reply- No longer a fan of Hydrolic lifters, I do however have a set of dual carbs and an FI So can build one of each, and If kent from Palm springs doesn't want the block I got him, or the core from the 73 is good I'll run one on the Eagal racing cam.
I see a clear answer in say 2 years
But thanks again- Bill _________________ some days I get up and just sit and think. Some days I just sit.

Thanks.
What do the swivel feet do?
As far as application. I'll start off with best dual car setup I can muster for under... in order of likely hood. Dual 34 epc, the. Dual 34 ict then dual 44 idf. .. if I get a big check in the mail. I'm putting this in a street Baja super with big rear tires, that I need to change from m+s to all season or even sport if I want to realize my goals. .
I intend to drive like Grape Ape.
And in all honesty. I really just want to peal out once in a while. But I've been told that this car will not.

X2 on the 1/2 ball type- The failures I've seen with them is they don't recover from a momentary failure (ie hiccup) in the valve train should you get a valve float or a momentary stuck valve- the flat on the ball can rotate and now your running on the round part of the ball. This will quickly mushroom your valve stem (pic to follow) The elephants feet will not have this problem. _________________ some days I get up and just sit and think. Some days I just sit.

Thanks. To both of you. Seriously
this is all new to me.
I am sourcing these.
But I pick up the motor (currently in pieces) in a few days and the seller says it has two sets of heads. Maybe one already has the elephant feet swivels.
Is this thing going to destroy my transmission? |

That would be nice. But if ine set does have swivel feet......post a picture so you can identify brand and quality.
If I had the choice between stock adjusting screws and poor quality swivel feet.....I would use the stock screws...because they will not destroy anything if they go wrong.
What WilliamM decribed is exactly correct.....if the half ball type swivel foot runs into problems the result can range from a damaged valve stem tip to a bent pushrod.
Also....you can buy several variants of the OEM Porsche swivel feet at Automobile Atlanta.....ranging from current Porsche stock at about $33 each to OEM replacment for about $24 each....to Mahle brand 911 swivels for about $21 each. Ray |

OK. So, unless I something bad about the swivels from statesidetuning I'm going with 10mm at about $90 delivered.
And will use whatever rocker arms are in there.
http://www.statesidetuning.co.uk/newproducts.html
Back to the motor.
So, my buddy picked up the motor in milk crates the other day.
Frankly, my buddy is doing most of the work and I'm doing the research.
The pistons need new rings, but are 94mm and comparing to some pics online they appear to be Mahle. They have markings 98,98 Std on them.
Right now the question is about the rings. Pistons and Flywheel.
The heads are 4 bolt (bus, not porsche)
There is no flywheel or starter.
I'm going to post some photos and I'd appreciate any info you all could provide.

I did just see an advert for a NOS 94mm set of mahle jugs for $200 that would be ready to go. unless the ones in the pic are some special dished ones that will make you coffee or something. |

that was lucky-- New race engine right around the corner for you-- Have pics of the heads and particularly the combustion chambers- that seems to be the trouble spot for these.
The choice of pistons is endless- almost-
I just opened up a box of mystery parts and found these slipper skirt beauties- Not sure how they might fit into a bus- now that the cam question has been answered- here (thanks RAY)-- One piece at a time till you reach a consensus. [img]
and did you see the cam gear I found with the "OK we're going to die now " cam to oil pump marks-[/img]

I need to get the correct flywheel.
Also, I'm looking at putting a set of dual h40s with empi manifolds on here.
Is there any reason not to? |

I'm getting ahead of myself but…
what are your thoughts on painting the tin to match the car?
I have a perfect match.
This is a pancake, so would it just make it more obvious that its not a doghouse look?
If I get this right, I will have cause to make this car pretty nice overall instead of "good'nuff"
I was kind of leaning toward the trumpet look exhausts.
Stingers look great, but they stick out at child eyeball gauging height. |

The tin paint....whatever looks good for you.
The exhaust....dual cannon style like that are positively the worst exhaust money can buy. You will lose lots of power on these engines. Put a proper header on it. The muffler.....pr just a stinger even....is your choice. Ray |
