Last Oct, we were drag racing on the deck of the USS Midway. I'll have to send you a pic. Once in a lifetime opportunities.

(video shows the speedo). Ran Valvoline 10/40 but think I'll switch to either Delo 400, Rotella T or Mobile 1.



Your very welcome man no problem. Sounds like you have the combo nailed down for a reliable high performance car. If it were me I would run the synthetic rotella 5W-40 but you cant go wrong with any of the ones you listed.

Wow, amazing car...

Any pics of your pro street Camaro??

Forgot to ask, is the 15/40 Rotella a dino oil & is it heavier than the 5/40 Rotella synthetic? I'm interested int he syntheric, but am a little worried about a leak developing somewhere. Motor doesn't leak a drop now, but sure don't want it to start.

15W-40 is dino oil and 5W-40 is the synthetic. The only difference would be the 5W-40 will flow better in cold weather. Other than that a 40wt is a 40wt no matter how you slice it. I say go for the 5W-40!

Here you go. It was cloudy this day so it doesnt show the true color of the car. It looks candy apple in the sun. I dont have unlimited funds so this car has been a project thats been going on for 11 years now. I originaly built it to drag race but had a bad accident in my other race car and decided not to race this one any more.

Here is the 383 stroker while I was building it. Notice the big domes sticking way out of the cylinder bore. It is 13.5:1 compression. This picture shows the dart heads. I later swapped for Brodix Track 1 Aluminum heads. It made close to 650 on the engine dyno.

Beautiful Camaro & 650 HP from a small block stroker is awesome. With that light weight, bet the car flys. Big bucks for race gas these days. I'm building a 451 stroker for my 68 383 Barracuda & w/ the Eddy heads worried about not enough compression. We got the 9.5:1 Ross pistons w/ the stroker kit, but w/ the big chamber eddys, think I'm way too low. May swith to the smaller chamber heads of mill mine to get at least 10.5. Anyway, what rear emd gears are you running & what ET's does it run?

Yeah it sounds like you might need to get the smaller chamber heads. With aluminum heads and a good tune you should be able to get away with 11:1 compression on 93 pump gas.

The rear end gears are Moser pro series 4.56 in a 12 bolt with a moser spool and 33 spline moser axles. The car is 3500 pounds and I am 240 so its pretty heavy. It ran 10.80's with a converter that stalls way to low. It is a pig off the line with only a 1.6 60'. The converter is only stalling at 3000 and it needs a minimum of 4500 stall. With the right converter we are thinking it would go 10.50's but thats just a guess. Since i only drive it once in a while on the street now days I figure why bother putting a $1000 converter in it that will make it that much more unstreetable than it already is.

Here is a short idle video. It has to idle at 1500 in order to idle at 900 to 1000 in gear due to the super tight converter.

Valvoline VR1 or M1 15w50 would work well IMO.

Here I thought you might like this car. MMMMMM Blown 426 hemi and candy apple red!!!!!

Very nice! & thanks for the link to your video. Running in the 10's must be a great feeling. A friend who builds hemis said he uses Quaker State Extended life since it has Slick 50 in it & adds a bottle of Comp Cam's zinc additive. He no longer uses Rotella T because the zinc has bee removed. I'm not a fan of additives, but is the new Rotella T still good enough to run w/o an additive?

It hasnt been removed! It has been reduced a little but still has more than enough for a flat tappet engine. If memory serves me right it was something like 1200ppm in the new formula.

I would give my left-nut for the Super BOSS. It's a 494ci BOSS 429. Makes 735RWHP (About 850 to the crank using the 15% rule) and runs mid 10's on a set of polyglass tires

and is a piece of 60's drag-racing history.

The stigma associated with cars like this, the old Road Runners, Challengers, Chargers, 'cuda's....etc. This is something the Import fanboys will never understand. They don't have a heritage of cars with bad brakes, on [censored] suspension making ridiculous power figures from nothing more than gobs of cubic inches and trying to put it to the ground on bias-ply tires offering up not much more in the way of traction than something made of plastic.

Cars you DROVE to the dragstrip and DROVE home later. And if somebody called you out, you ran them. Not making up lies that your daily driver 4-cylinder ran 9's on street tires. That kind of talk would get you in trouble.

Your Hemi doesn't run on diesel fuel so why run a diesel oil? You can't go wrong with the Penn Grade 1.

I hope there was a little sarcasm in that...

 

[BuickGN]

And very, very nice cars. The Sonic in my town used to be full of rare old muscle cars on the weekends. It gave people like me who are now in their late 20s and early 30s a chance to see what it was like back then. It was awesome to run against some of these cars win or lose.

 

[FiremarshalRob]

Trigger, you have an amazing classic there.
That has always been one of my favorites, the Hemi 426.

I am without words. What I would give for a ride in that beast.
