Proverbs 3:5-6 (NKJV)

Be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God;
Philippians 4:6 (NKJV)

“So I say to you, ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you.
For everyone who asks receives, and he who seeks finds, and to him who knocks it will be opened.
Luke 11:9-10 (NKJV)

I will answer them before they even call to me.
While they are still talking about their needs,
I will go ahead and answer their prayers!
Isaiah 65:24 (NLT)

While I appreciate your quotes of the scriptures, I'm not sure just what your point is.

"And whosoever shall not receive you, nor hear your words, when ye depart out of that house or city, shake off the dust of your feet." Matthew 10:14

I'm not ready to do that just yet.

Great Scripture-- Very fortunately though, Those words (scripture)
are directed to the Apostles (and us) on speaking and sharing the Gospel of JESUS.

The point of Scriptures I shared is to Motivate you to get God Involved in "ALL" things

Even, car troubles

Effort...really it's not that much effort but I appreciate the sentiment. It took me about two minutes to make my last post because it only contains facts and the facts are not that complicated or numerous, two more minutes for this post.

You on the other hand need to be applauded for all your effort because it is far far far greater than any I have ever made. Your post count on this thread alone, never mind word count, demonstrates a mind boggling amount of effort, one which I cannot even begin to comprehend, why, is it really worth the insane amount effort???

Your comment about winning is a telling one...I prefer to spend my time on this forum learning and sharing factual information, but each to his own

Cheers, Paul.

I just added Peter, and as I was doing it, I thought again about how impressive it is to see that some of the owners in other countries, are addressing this issue in the same way.

When I started this out, I expected to come across a handful of cars from a few major cities, towns and hamlets.

I never expected to see that it was being done on this wide of a scale, but it makes sense.

LS 7 engines from what I can tell, can apparently be difficult and expensive to obtain outside if the continental United States.

Thus people appear to be taking thus step to avoid being in the position if having to procure one.

Keep the reports coming guys, and good luck.

I wouldn't normally consider myself an elitist but apparently this is the unfortunate 'cost' of recognising I am not likely to be immune from the laws of physics

I just got an email from one of our Canadian members. He wants to do exactly what I have done. I told him to call Richard at WCCH. So look forward to another international addition to your listing

This fool would rather part with $4300(total cost for new PRC265 heads, gaskets, head bolts, plugs, coolant, oil, labor, etc) than part with $17,000+ for a new engine, installed, because of a fist sized hole in the side of the block of the old one.

Assuming you began with GM heads which had the QC machining issue this would be a wise way to proceed because it is unlikely the PRC heads would have the same machining issue.

You could also go with something like the new TFS head for the LS7, BUT be advised that if you were to use the TFS head they come with SS valves and as a result limit themselves to an absolute high of 6700 rpm for a rev limit. I got this information directly from the chief of their dyno operations who said they would have to place their limit lower IF they were as unwise as to not use a good beehive spring with an aftermarket cam.

I've said it before, it's hard to get a worse combination of parts for the LS7 than dual springs with heavy SS valves AND an aftermarket cam...and just because someone can produce a list of a few guys from all over the world who have chosen such a bad cocktail of parts (assuming one wished to continue to use the 7100 rpm limit of the LS7) doesn't been the laws of physics suddenly become null and void.

Cheers, Paul.

Paul,

How much horsepower are you actually loosing by not spinning the car up to 7100 rpm verse's 6700 rpm? Second when you shift at 7100 rpm are you lifting or keeping your right foot planted to floor?

I reused my stock castings. A competent machine shop will verify clearances, valve seat etc... Total cost was right under $1100 bucks with machining, SS valves, PRC springs etc. I chose this route vs. new castings. Machining plus labor was right under $1800 bucks through a forum vendor.

I will say I wish I did a little milling and porting. At the time I wanted to keep it stock but that went out the window a week after having it back. I threw a cam in her myself and had the car re-tuned.

I think there is an example of a car built like his in here which has already dropped a valve.

Yeah, here it is.

http://forums.corvetteforum.com/c6-z...post1579173826

Same people built this car using the stock valves, built his. That's why his screen name is what it is.

Consider that above car when you think of taking advice from him on this matter.

Looks to me like it might be better for him to concern himself with his own setup, as opposed to ours.

Do yourself a favor and don't feed the trolls FSTFRC.

None, in fact you're gunna be making LESS hp at 7100 than you are at 6700, BUT you're loosing a boat load of hp AFTER the shift because of how much lower in the rpm band you drop.
