When it hits the Hashed zone. Followed by the AC immediately kicking off. This happened to me years ago when I was having radiator/water pump issues

Re: Who's Modding this winter?
 

Thanks
Wow,i just checked the chip programming and it's showing A/C Disable coolant temp 123.50 celsius or 255*fahrenheit.

Re: Who's Modding this winter?
 

Well... looks like I DO have a winter mod project after all!!

Re: Who's Modding this winter?
 

Yeah it isnt pretty :cheers:

Re: Who's Modding this winter?
 

Mine got to maybe a 1/8" away from the hashed section. Got there once before (at Bloomington Gold last summer when sencondary fan motor quit), and all seemed well, in spite of it. (I haven't done a compression check, but it ran really well at the dragstrip, so I'm assuming it is OK. But, it does seem to use a quart of oil in about 2000 miles; a little more than before. I'll do a compression check Saturday to see if there is anything to be concerned about... F'n spring clamps!!:mad:

How many miles on the car Paul?

Re: Who's Modding this winter?
 

51,1xx miles.

Re: Who's Modding this winter?
 

I was using the same amount of oil on my 91 in the 60K range.

Re: Who's Modding this winter?
 

Whew... Well, that's comforting. But, I'm sweating the (near???) over-heating episode now...paranoid, I recon. Long as the gasket held (again), I guess I'm alright. $$$ is really tight right now, and I really hate to see what the compression test might show. :( Then again, the courageous only die once, and a coward dies a thousand deaths. I guess I'll get it over with! It would be a "bit more" than a winter project to fix the short block…:o

Paul,

The 91 was doing this when I got it. It would spike to right at the hashed section and this worried me. The PO told me it "did it sometimes" and that he had Marc check it and clean the radiator but that it didn't help due to the wiring from the battery being too small to run the fans at idle (or something like that). But this was happening going down the road... Well I went to looking and the WP was leaking and the radiator clogged. Once all of that was repaired (new WP and removed and cleaned the radiator) the Z stays nice and cool now. Anyhow point being I think our Z was done that way for a long time so I think you are safe if it just did it once on yours.

Re: Who's Modding this winter?
 

Paul, i'm sure all is ok.

Here's a little something that might cheer you up.

I found this looking for something else the sad part is i remember when he was selling, this ad was December 2002,i was porting my heads that month and dyno'd March 2003.

Re: Who's Modding this winter?
 

Wow!! That IS interesting!!! ("None so blind as those that WILL NOT SEE";))

But, back on topic, I've got an idea for a mod to toss onto the table at our FBI performance & engineering...er... "pizza nite" (I meant to say) on Saturday. It might make for an interesting hp adder. :cheers:

Re: Who's Modding this winter?
 

Looks like the added cubes in the 368 show up as better torque numbers than the 5.7L. Doesn't say whether these are stock cams. Larger displacement is probably being limited by the smaller cams. I wonder how much "porting" the heads and IHs have. Probably not as much as current day work. So could better porting and bigger cams get the 368 over the level Pete has on his 350? And how about the ROI on that.

Pete,

Would be interesting to see diff in cost of your package v 368 using your cams and porting.

Re: Who's Modding this winter?
 

Dom,

Yeah, I studied that too. The cubes are adding to torque - no doubt in the mid range. (Then again, Pete's RWTQ is above 400 with his 5.7L) If I recall correctly, my RWTQ is 378 at 5200, but peak hp is 432. Doing the graphs in my head, I suspect the SGC 368's torque is falling on it's nose, somewhere above 60-6200 rpm. So, porting AND cams of yore come into question. But, it's pretty amazing what "some people" have accomplished in the past decade (since that 20 year old stuff was done...;))

U be @ Home Run Pizza Saturday???

P.

Re: Who's Modding this winter?
 

Cubes will always make more torque.

Dom,it's been a while i can't remember what cams were in it.
That would be a pretty sad 368 if it had cams.

The differance between doing a 368 ($12-$15k) or just top end port work on a 350 i would estimate half price.

Re: Who's Modding this winter?
 

I did a compression check on the cold engine that hadn't been run for a week.

I put the battery charger on to keep the battery topped off (battery ordinarily has a Battery Tender on it full time.

I pulled all the plugs, and they all looked identical; whitish with ever so slight amount of brownish tint.

I ran the starter for 6 compression strokes each

Compression** (all the plugs out except the one with the meter) ran between 195 and 205, except one was 185.

**Note: the plug with the lower compression was the #3 hole; the one where the coolant burst through the IH wall as result of it being thin due to some porting. Marc said it might well be due to the fact that the chamber may have been well decarbonized by the coolant. Maybe.

Am currently running an oil consumption test, tho there is no smoking that I can see at idle.


WINTER PROJECTS: Which brings me to another winter project: An oil catch can. I currently am not entirely satisfied with the ones I've seen: too pricy, or obtrusive, or both! I kinda like the ones Bob and Al came up with for their big inch motors; approx one pint capacity, custom can that sits down by the driver's side headlight. The plumbing is such that you would hardly notice it; taking advantage of the stock piping (as I recall) so as not to clutter the view of the powder coated motor with plumbing. (Looks nice as you don't see it!)

Re: Who's Modding this winter?
 

Mods:

1. Rear SS brake lines/brake fluid
2. Headlamp motor gears
3. Driver's seat bolster repair

Re: Who's Modding this winter?
 

Paul, I agree with you entirely. Al, Bob G catch cans look great, I was looking at Al car in bowling green it was a clean install that looks like it was factory installed. I am also looking at Radium oil catch cans as they use a Stainless steel condenser to remove the oil. No junk media to break apart.

Re: Who's Modding this winter?
 

Well..........................I had somethings planned and then I found this 63 Nova S.S. convertible.I wasnt in the market for another car right now but just couldn't pass it up,this makes Nova #5.Its got some very minor rust issues but none in the floors,trunk.So much for my new wheels.[IMG]http://i10.photobucket.com/albums/a1...M/DSCN1092.jpg[/IMG][IMG][IMG]http://i10.photobucket.com/albums/a1...M/DSCN1094.jpg[/IMG]
