    [quote=”Qball” post=3911][quote=”oestek” post=3877]I know the story because I listen to http://www.v8radio.com , but what’s the latest?

    Well…..Not much to add at this point. I’ve talked to Ray, my machinist, and he tells me that he has all the parts he needs to put the shortblock together but needs to find the time to get it done. I have mentioned that he has a mountain of work at his shop, haven’t I? I asked him (somewhat snarkily) if he’s thinking about having it done before winter. his response was an emphatic, OH SURE!! Time will tell.

    I’ll leave you with this, if my block were a new born baby when I dropped it off, it would be walking by now and able to use rudimentary words to communicate.

    That is all.[/quote]

    Wow, you could have a talking GTO engine. That would be awesome.[/quote]

    Ha! At this point, I’d settle for just a plain Jane GTO engine. No talking necessary.

    Hi. Just wondering if there is an update to this? If I’m reading it correctly, the shop had/has you block for over a year and has not finished it? My first shop had my engine for several months. I would call every week and get the same “we’re progressing” then a runaround when I asked for specifics. When he finally finished it the bearing clearances were set at .005! not the .003 I asked for. And I was charged for labor to cut the heads to accept dual valve springs and the work was never done. He just slapped it together to get me to stop calling and bugging him. If the shop STILL had your block, get it out of there and find a new shop.

    There is an update! Mike goes over it in this episode of V8 Radio:

    Ha! Indeed there is an update that’s covered in the latest episode of V8 Radio. In a nut shell, a ruse was orchestrated in order to press my machinist into action.

    I have the block back along with the new rotating parts. Nothing was assembled, however, the rotating assembly was balanced and all the machine work was done. What I need to get is rod and main bearings along with rings. With that, I can get the short block together. I still need to source a cam/valve train.

    There’s been some heated debate as to which heads to use. My current heads are stock 670 cast iron heads. The combustion chamber was cc’d at 77cc’s. The static compression ratio comes in at 10.3:1. The consensus of opinions is about 10:1 that it’s too high for pump gas. I’m inclined to agree. I may have a line on some 6x heads that have a larger combustion chamber. That’ll bring my compression ratio to a much more manageable 9:1.

    There’s still many details that need to be addressed. But I have my engine back, I’m starting to see a ray of light at the end of the tunnel. C39BFDC4-0500-487C-BCE3-E25D0ADA8693.jpeg

    10:1 or even 10.3:1 should be doable with 92 or 93 octane pump gas. If in doubt, toss some aluminum heads on it. They dissipate heat better and help with keeping detonation down.

    My worry is where my power band would be. My GTO is a factory air car with a TH400 trans and has a pretty tall rear gear, 2.93:1. I’m worried about having to use a cam with enough overlap that it puts my power band too high for the rest of my combination. I’ve had too much mission creep in this project already and am trying to curtail it.

    Advance your cam 6*. It should move your power band down about 500 RPM. My Buick 455 red lines at 5500. Have 530 lb ft of torque way down low. Makes a fun cruiser. Mission creep… LOL. My mission creep began in 1999 and continues to this day. Check out my attachment.

    ”Might as well!” :cheer:

    Don’t forget the antecedent to that clause: “As long as…”

    As long as we’re pulling the heads we might as well replace the cam and lifters too. And a new intake can’t hurt. And as long as the timing cover is off we might as well replace it with a new one. And a new double roller timing chain set.

    That’s funny you say that as that’s how this all came to be. This engine saga started out as a simple, engine in car, cam swap due to a wiper out cam lobe. First a burnt exhaust valve was discovered when replacing the valve springs. Then when the heads were pulled, I discovered that the pistons were these low compression cast rebuilder double eyebrow pistons. So that’s when this whole thing went sideways. When the pistons and rods were pulled, all the rod and main bearings were obliterated. This whole thing was a ticking time bomb. We do this ‘cause we love it, right???

    My buddy started with a burned exhaust valve in his 71 GSX that turned into a $90,000 frame-off. LOL My trans not shifting right turned into a complete engine rebuild (we thought it was the cam grind, but after the rebuild it still laid over at the top and then we discovered it was the transmission).

    Just a quick test to see if Q-Ball’s subscription notification is still working after the changes to this forum…
