That is more lope that I want.

The current cam, that I have had for 15 years, is too lopey for my taste. I think that it is 234/235 112 LSA, my friend who ordered it thinks it is 232/234 112 LSA. I am daily driving this car, so I just do not want lopey anymore.

I am getting the big CID motor so I can have plenty of horsepower without needing a lopey cam.

Just a reference of a similar cam in a much smaller cubic inch motor. Ultimately it’s about performance first and your personal goals. Between this cam in my current setup and a 242/250 114 cam in my old 408 I’ve never had a cam that I’ve considered too lopey though. Lol. I understand your goals though.

Eric,
Since Tony prefers 4.155-4.185 bore for his heads, I think I will go with 434 as well.
The pistons you selected are Wiseco -2.8cc. You mentioned piston choice as semi-custom. Can you elaborate?

It is what Tony said. I am not sure what is custom and what is not. It is based on me needing to run 91 octane if I have to.

Thats a baby cam , bigger cubic inches eat up cam duration , for a really tame cam i wouldnt go anything under 240 on intake for the cubes u have... In my 454 im running 255/269 solid roller, daily it everyday, tow 3-4 thousand pounds. When i want it feeling mellow i shut the varex exhaust,

Please share when you get more details. I plan on having very similar setup with small cam and 91 octane at all
times.
In his build Scott (Che70velle) mentioned using Wiseco -8cc pistons in his 434. Not sure if they are custom, nothing like it is listed in Wiseco catalog.

While not a custom piston, they are semi-custom, built for an organization selling them as an entire rotating assembly. GFX ring pack and coated skirts, with a decently lightweight pin.

Where can I buy this rotating assembly if available to public?

No longer available with Wiseco Pissedons. They now sell with Mahle pistons, which I’ve ran in the past and are a good product. The Mahle slugs are fully coated.

Go with diamond pistons. Best on the market.

Ls1 5.7 piston weight below... The Wiseco pistons weigh 447 grams. The stock piston weighs 435 grams. Dismond pistons are 405 grams.

The same laws of physics will apply to a larger piston as well. I bet in the real world the lighter piston will REV faster.

Based from past experience, I really like Wiseco pistons. Mahle brand seems lower grade to me, but coming from you Scott, I value your opinion a lot!

​​​​​​​
I never dealt with Diamond pistons, I will google-research it.


Static compression with -2.8cc pistons in this application is a little too high for pump gas at 11.9:1 with 70cc chambers.
-8 cc pistons would be perfect with slight head milling.

I curious about these semi custom Wiseco pistons that Tony suggested to Eric.

What does everyone think about me replacing my wire harness along with the motor? I am this deep into the car, and it is 22 yrs old, and the car has been in the desert for its entire life.

I am thinking, might as well replace the wire harness while everything else is out.

I will tell you it crumbles bad on you. I yanked mine for the same reason. The cheapest option is to get a loom kit from jegs and rewrap it

It all depends on the actual condition of your current harness and your know-how.

My harness is just as old, but only has 26k miles. I enjoy doing this and went through my harness myself.
I removed all plastic looms, removed and cancelled unused circuits like AIR pump and original primary oxygen sensors, switched secondary oxygen sensors to become primary due to wires being longer and capable to reach headers.
Inspected all the rest for stiff/overheated wires, chafing, broken connector tabs and loose terminals.
Added extra protection from heat and rubbing contact in some key areas.

If your harness is beat up, go with new.

Harness deterioration is more about time and exposure than mileage.

cino

I’d argue it is more related to heat/engine hours which translates roughly to mileage.
I don’t believe harness really deteriorates when the car is parked indoors.
The heat is a big factor. I suppose in South harness probably deteriorates faster than in North.
Especially because in North we store away our summer rides cars for winter months extending harness life by a good margin.

Nothing was dry, cracked or otherwise and I could reuse all wire looms on my original low mileage 22 years old northern engine harness.

G Atsma

I agree with this. In addition, any grime/crud/grease exposure over time will also take its toll. I was thinking of this when I replied above, but should have clarified better.

I can run wires and terminate wires like a champ! As long as there are no fiber optics.... those make me consider cyanide.

I was hoping that you would reply, since you used to be in the PHX area. I tend to think that replacing items is always a good idea if you are already there. i.e. new intake = new gaskets, spark plugs, spark plug wires, IAC, TPS, MAP.
