Do share, what exactly is a Max effort LE2? The heads are what the heads are unless Lloyd is going to spend some extra time in the porting process for a little more money. I brought that to his attention even speaking to him recently myself but he never really gave me a clear yay or nay on whether or not he was willing to give my heads a little more effort for more money.

Ls1 lid, true dual exhaust system and so on. I have to have cats I can't not have them. Like I said it's just gonna be a street car it will never see a track I'm just building it for fun for a weekend car a d to take to car meets and stuff.

If the car makes 380 rwhp or it makes 410rwhp I'm not gonna care I'm going to be happy either way. If no one ever told me I probably would never know the diffrence.

Well, not to burst your bubble but with a good tune being a 383 it should make well over that lol!

That's the cheapest I've heard in a long time.

Beware....you often get what you pay for.....

I'd go with Ellwein or Golen.

EDIT.....I see you went with Golen.

No….I'm 99.9999% sure that it will not.

Why? Because this plate (TCI-399173) for an externally balanced engine.

Call Golen to verify, but I'd bet a dollar that they are (internally) balancing your rotating assembly.
.

That being the case, you need the TCI-399174 plate....for internally balanced engines.

https://www.summitracing.com/parts/tci-399174/

AND I JUST HAPPEN TO HAVE ONE SITTING ON MY LAP....BRAND NEW IN THE BOX!

$80 shipped to your door.

Again....call Golen and verify your needs, and then if you're interested in my offer, drop me a PM with your email and I'll send your pictures.

I spoke with him Tuesday he said he builds them like stock lt1s interns of babalncing. Back is external and the front is internal so you use the stock balancer or stock style rather.

I have called chad several times now probably asked him 100 questions. Honestly the reason I chose Chad over anyone else is that he has been fantastic on the communication and he has no problems answering questions.

I really appreciate ****** pushing me to call him.

Yeah Chad is good on the communication. He did my motor back in 05 and then he was doing full "internal" balance so I use a neutral, aka zero, balance FW. There was a paper sitting on top of motor when I opened crate saying "INTERNAL BALANCED MOTOR, MUST USE NEUTRAL BALANCE FW/FLEXPLATE". If he is now doing external rear balance then you can use a stock weighted Flexplate or FW

Golen short block & LE H/C package is one solid motor. With the LE 2 set up you should be around 400 RWHP +/-

Golen provides/includes the block in their $. Shipping is extra per destination but Golen does crate the motors

I'm surprised by that.....but it's all good.

In that case, the plate you listed will work just fine!!

On another note I have a new in box full Torqhead 24x kit that I won't be using. I am selling my z28 so I won't have a car to use it with. It is a full kit that has never been used or installed. Hub on it is for an ATI damper. PM me of you are interested in it at all. I will make you a good deal on it.
Do you still have the kit

Ok guys a little update.

-As stated Golen is building a 383 it's going to be 11.5 to 1 compression. Doing a 4 bolt main with fully forged internals. Golen is also doing the complete assembly from intake to oil pan.

- lloyd is doing a le2 heads and porting the intake. He Is also doing a custom ground cam. I am not sure of the etiquette on posting cam specs so I am not going to at this time.

-i ordered 36lbs bosch injectors that are being flow matched.

-also ordered a full 24xkit with stock hub

-i bought a new 58mm tpis throttle body from a member.

Things I'm buying in the next two weeks
Sfi flex plate, kooks headers and catted y pipe, sending pcm to moe for tuning,

Hopefully we will being installed the motor back in the car the second week of october.

No I have to have cats to pass the visual inspection no way around it. No I am not going with a emissions cam.

At some point in time you need to get an ORY. It'll be a significant difference especially with a stroker.

Chesapeake Virginia. Its weird how the law is written it says after a car is 25 years old it doesn't need to pass emissions. However I don't know if they mean sniffer or visual.

Either way I'm probably going to gut them I honestly just didn't want to admit that online.

I think what is meant is after 25 years you can apply for historical tags and you won’t have to do emissions and possibly visual? However you will only be able to drive it so many miles a year. I used to live in warrenton and looked into this, but i can’t remember the specifics.
Also, unless you have a hookup on emissions, you will need to make sure the sensors tested are in a “ready” state. If you have too many “not ready” sensors you can be failed. Google something like “OBDII emission testing” and there’s a page that goes into specifics. You can get them tuned out if you haven’t already.
Also, i’d try to get the engine completely internally balanced. That way if you have to change out flexplate and torque converter you can have them neutral balanced and not run into any issues. JMHO.

I'll talk to him on the neutral balance today.

On my 95 I don't know what they do I'm pretty sure they don't hook it up or anything. Since I'm not in a country the required a sniffer test that makes it easy.

I thought about getting an ory as well and just throwing it on the lift and just swapping them after the inspection.

It was so easy to get passed the inspection in NY.
