1963 Grand Prix

I left my mess outside with the lights on, have quit for the night before I get skunked moving around ot there.
 
I can relate to all your family woo’s. I think that every man goes through that in his life. Sometimes I think the issues we have with the wives is:: both get complacent with everyday mundain things in life and lose site of the spark that both need and seen in each other. It’s a lot of work on both spouses. As for the kids…. I think all kids are naturally disrespectful to their parents to a point.
 
The C4 ZR-1 is a car to get and put away in your collection later. Maybe sooner.
It's a Performance Driving and Racing Legend.
You want alot of cars like me.
That Elusive SD455 You have wanted.
Its going to take big dollars to obtain a clean one. $50,000 at least put away for.
$150k better.
I met talked to most of SD455 Owners worldwide, did some Racing Tech for them Race Math for those still Racing them on SD455 Group FB.
 
SD455 Usually had Air Conditioning with Automatic Transmission TH400.

They made SD455 No A/C Muncie 4-speed for Street Racers like me.
 
plus the heads you should post some pics of that work
Heads I am proud of.
2nd set of heads perfect Full Race ported by me.
60-70 cfm more than stock !
9.6 :1 static ended up at 8.4:1 same as SD455 Trans Am used.
It runs and Zero detonation issues on pump gas 93.
Had it running on 87 one day just to move around. No higher than 3,000rpms used on 87, full Ignition advance all in, no detonation noted observed.
 

The 1976 Pontiac 455 Dream started here.
Next morning after I bought it and drove home with it from Iron Ridge Wisconsin.
From a 1976 Pontiac Grand Prix.
Started off as a 200 Hp engine.
Pontiac left full mains thick webs and Full thickness castings in all later 455s till they quit production in 1976.
It's also Machined Super Precisely Factory I noted.
Was the perfect Survivor Sleeper Street Race Core.
Been almost 2 years now when I made this video.

Do me a favor and post this video for Grumpy to see on his site.
Tell him I ported the heads and intake myself.
Learned from Chad Spiers and guys on Facebook. Tell him its runs Awesome. Entire build in video description.
Is that a whole 7" of vacuum at idle I see?
It seems that Brian went for the BIG cam at the bottom of the page.

9 inches steady now Mike at idle warmed up @1,000 rpms idle.
Driving at 80-90 mph where it cruises nice at not working the 455 even hard any Its 16-17 inches intake manifold Vacuum.
Off the gas after a Wide open throttle there is 21 inches vacuum decelerating.
100 mph there is 12 inches intake manifold Vacuum.
Punch it drops down to 0 inches intake manifold Vacuum.
Using the factory Pontiac Vacuum guage on the console.
Checked against another Vacuum guage the Sun shown in video it is accurate.
In gear hot engine fully warmed foot on the brake held I see about 6-7 inches.
Varies with Air density day to day in the summer heat.

Actually chose a mild cam of sorts, real similar what we used in Turbo boosted cars for 1000+ hp.
Tighter LCA 108.
Isky 280 Megs 232@ .050 single pattern.
Installed 105.5 ICA. Degreed in .

Believe the Vintage Offenhauser 360 single plane intake is dropping Vacuum some at idle.
Past experience with 1970 Factory Pontiac RAIV Aluminum with Long runners gave better intake Vacuum.
TA with seen 5-7 inches at 1000 rpms Full drag cams.
 
1st few videos it running it was pig fat rich still.
9380 had to be jetted down alot.
Recall I calculated on paper 33% reduction in Jetting square surface area primary and secondary jets each.
Started to wake up and power unleashed.
All tuned this far reading spark plugs.
Have my AEM Wideband Lamba 02, new in box yet haven't installed.
Still Old School I want to tune reading spark plugs, test drive 0-120 mph.
The Burnout Tests done.
 
The Olds 425 was no where near as powerful.
Its actually decent on Fuel MPG cruising steady 80-90 mph No Overdrive TH400.
About 14-16 mpg.
Pretty good with a huge cfm 4150 Double pumper carb.
 
To reply to your earlier statement about “Putting cars away.” That has to be left to the guys with the means to do it the right way. Great storage, great mechanic or mechanical skills yourself and MONEY! Lots of money.
Years ago nobody cared. The tires looked good, that was it. I’ve got 4 sets of Brand New - not “looking brand new” they are Brand New with no miles or maybe a couple hundred at the most. I installed them, the car sat for 10 years and everybody says “no good!” they’ll rip apart on the highway. So the first thing buyers look at on my cars is the dates on the tires and beat me down for new replacements or better yet for them, discount the car by that amount.
And God forbid life happens and you get jammed up for some reason and you can’t take care of the cars. It get so costly I don’t know how most of the collectors do it.
