Lol. I was just being a dick

 

Really?
I was in tears.

 

You posted that at 4am (Eastern time...no telling where you are right now) and I’m thinking to myself, does Darth ever sleep?

 

Maybe he is a vampire of some sort.
Either that or high on coke.
Haha

I have sleepless nights and am awake late sometimes.

 

Plenty of time to sleep in the grave.

 

a-1performancewarehouse on eBay usa. The heads were done by ECR engines for the Daytona nascar race.

 

Did you try contacting higgins?
They also sell small bore ls7 heads.
Designed by Darin Morgan.
Might have saved you some mucking about.

 

Yeah I know there's others available including Higgins. I bought these because I believe these ecr heads will work very well. Nascar teams spend huge dollars on engine development. These are only 235cc intake ports and they made 600fwhp with some serious intake restrictors (per the rules) on little 331ci destroked lsx (4.065 bore) with only 240/590 solid roller cams. At the end of the day they've cost no more really than any other small bore ls7's available even when I give in and buy the spray oiler covers.

Info PDF on the ecr engines (not sure if this will work) ..

 

PDF file doesn't want to upload for some reason.

 

Fair enough.
I think from memory the small bore ls7 heads from higgins will end up costing around 7 or 8 k once you purchase the required shaft mount rockers.
I'm not sure if the ls7 manifolds would work with them.

 

Camshaft and lifters were dropped off at engine builder today.
Car should be ready in two weeks.
We also compared the weight of the normal hydraulic street morel lifters to my howards morel 5425.
There was a big weight difference.
It's amazing how much lighter the solid lifter really is.
There is a 900g saving of weight just there.

 

Should be a beast.

 

Below is specs of a 243/250 comp hydraulic roller I bought a few years ago and I haven't used it. 13021R / 13164R
HR 108.0 It looks like new with no wear.The previous owner (aussie) said it made 500rwhp in a n/a stock stroke ls3. Not sure what heads he had and he pulled it out to go boost. I'm going to try this in my ls2/ls7 heads build, but run it as a solid and see what happens. It's very similar specs to the old T-rex but not on xe-r lobes. And I have 1.8 rockers which will bring the lift to around .650/.640 after lash

INTAKE ..

XTREME ENERGY™ LSL HYDRAULIC ROLLERS FOR LS1
The LSL Series has been designed with enhanced characteristics from our latest professional drag racing profiles.

These have excellent ramp quickness but are designed in a way to improve stability over other designs with such short seat timing. The increased lift works well with the latest Gen III and LS cylinder head port designs by providing excellent area above 1/2" valve lift.

XTREME ENERGY™ LXL HYDRAULIC ROLLERS FOR LS1
The LXL Series is based off the popular LSL profiles but are optimized with lower acceleration and a softer closing ramp for less valve train noise and better stability with higher (1.8:1+) ratio rocker arms. These profiles are an excellent choice on the exhaust when used with an LSL intake and perform well for both the intake and exhaust when used in either LS7 or other high ratio applications. These also are a great choice for road race type engines that require extended use at high engine speeds.

That's a pretty aggressive camshaft.
When my new LLSR is converted to a hydraulic it is a 244/252 114LSA +4
Just make sure you have suitable rockers and good lifters.
Those LSL lobes are not as stable as the newer lobes that are out.
Based on my negative experiences I would only run that as a solid roller with that much lift.
Also lash doesn't alter lift. Only duration.
If you want that camshaft as a low lash roller from cam motion the specs would be 249/257.

 

Lash does reduce max lift by the same amount

 

I don't think that is right spanks.
I'm quite sure the lash only alters the duration (on a low lash solid roller) by 6 degrees on intake and exhaust and doesn't affect LSA or valve lift at all.
Can someone chime in here and confirm this?

 

I have T&D steel roller rockers (pic of them below I took earlier in the year). The lifters I still haven't bought, thinking I can get away with the Isky solids that use factory lifter buckets that I mentioned to you earlier in this thread. These heads don't need overly heavy springs with that cam as the heads have 2.100" titanium 7mm stem intake valves (very light) so thinking it won't murder those lifters too much. The lifters are just about the last thing I need to decide on and then measure for pushrod length.

 

I'm not yet quite sure what running this cam as a solid will do to final duration or lift or lsa. I will also run a bit more lash than what the cam motion llsr's run just to be safe as this cam wasn't made to be solid. People have done it often though run hydraulic roller lobes as solids. Apparently it's a little bit harsher on the valve train. I might run it for a short while then swap it out with a boost spec cam motion llsr if I decide to go boost afterwards. Depends on how this thing works out. Definitely not going to bother running anything hydraulic unless I have issues with the solid setup for some reason. I do need to run lash caps on the valves because of the titanium valves so I need to be careful with the lash that it's not ever loose enough that a lash cap can fall out, which I've read has happened to people running solid cams and lash caps. That's what I get for buying nascar parts, have to be fanatical.

 

Nice looking build man.
Nice and clean.
I want to make love to that intake port.

If you are running a solid cam don't skimp on lifters.
Buy the best ones you can afford.
Cam motion and another member on here told me the same thing.
Needle bearing lifters can fail suddenly.
Which is why Buy the best ones you can.
If you have the money go bushed.

 

Lash reduces peak lift by the amount of hot lash
