It may be too soon to start this build thread but here it goes.

Its gonna take me sometime to not only get the parts all together but make the money and have time to do the work. Besides I have lots of changes going on with the car this winter.

I am now the PROUD owner of the only 4.750" stroke Cadillac 4340 Biilet crankshaft outside of Courtney ..

He had 5 made ..He has 4.. I have the other ...

After many conversations and emails about a girdled block I finally made a deal to get one. At first I was only going to get the girdle and fit it to one of my blocks and cranks.. Overtime that progressed into a completely machined block with a girdle fit to it..

To much nitemare possibilities going thru the local machine shop chebby clowns..

He had his shop start on 2 blocks with girdles to

A. Have one on the shelve

B. Get a good idea on cost for labor..

Time is not important so its taking alot..
Hahaha

Excellent!!! Can’t wait to see the progress on this beast!

Sounds like you fell into the rabbit hole of the engine build! Is this going to be the turbo build?

Turbo or supercharger or nitrous.
Haven't made up my mind. ..

If it wasn't going to be one of those I would be looking at 12 to 1 a huge cam and .120 or .140 overbore.. 583 or 588
With enough cam I think 12 to 1 with those heads would still run on pump gas

If nitrous it would be several stages of it and lots of it. ..

I dont like nitrous. Never have. It's the expense and complications of running turbos. .. roots supercharger I think is out of the question. Modern superchargers like Pro Chargers to make this power level are extrodinairily naw
MIND BLOWINGLY expensive

The Sniper is limiting my hp output with any boosted app.. they say 1250 max. But who knows if they are exaggerating. I was hoping to push that level by upping fuel pressure from 58psi to say 75psi..

With nitrous that becomes much less an issue.. supposedly the 4500 Sniper can handle 1500 hp that way.. but if the nitrous were not fed thru the Sniper who knows

Nitrous,:cry:! Turbo,:cry:! Everybody is doing both:sleep:! Supercharged,:):thumbup::D, yes, yes. Nuttn' like a giant piece of aluminum sticking out of the hood for obstruction of vision tickets. And of course the wine. Try the blower shop for new. Or go to Dyer. Or go to queerbay for used. Got an 8:71 used for 1600. Took it to Dyer, since he's just three miles from me. He said I got it for a good price, checked it for free and said "run it"

Blowers look great but ive already had bad experiences with one.. and by the time I actually had it on the motor it was not a cheap adventure for sure

I had a 6-71 it ate itself and the Cadmaro was actually faster without it

Bro. Cad Man,

I had started to write you a proposal for a fuel injection throttle-body having injectors that can supply approximately 2600 horsepower - on gasoline and which flows 1,000 CFM naturally aspirated. That fuel system would be combined with a turbo setup, either single or twin.

However, I went to check the availability of some components and lost what had been written. So, in the interest of time - would you have any interest in doing something along those lines? If not there is no need for me to source and price out the components.

6:71 not big enough for the Cad. Just a big waste of money. 8;71 the smallest. But for what you're planning, 14;71.

Bro. Cad Man,

I have an update to my above proposal. I have confirmed the price and availability of both the 1,000 CFM throttle-body and the four injectors necessary to support your goal of approximately 2600 horsepower. I'm more than pleased to say that the prices are very, very modest.

The component that is "on hold" involves the electronics for the fuel injection. There aren't any off the shelf ECU's (that I have found) that are spec'ed for that level of performance. HOWEVER, I am working with a gentleman who has extensive experience with electronic fuel injection, including a number of current vendors. He and I go back many years so this is an established relationship. He will be reviewing current EFI packages to determine if any might be upgrade-able to your desired level of performance - and if not, if a one-off system can be fashioned - with expected reliability, and at a reasonable cost.

Due to other commitments the gentleman can't get started with his ECU review for at least a week. I'll report back at that point.

Question: Do you know what fuel system the high powered CMD engines use?

Best,

bro. d

I have never asked. ..

The Flash was mechanical injection
made up and mixed parts .. including 2 homemade 4" toilets

It seems he was telling me to use Aeromotive

Just to be clear, what power numbers are you really looking for? That 2600 number came from somewhere, not sure where, but maybe my arse. :rolleyes:

If you are still thinking of a supercharger. You might wan to checkout Alkydigger.com for LOTS of injector stuff. Of course you would have to get the intake from you know who. Unless you keep watching boobbay and get one like I did.

But what you are talking about ain't cheap either. Why not go for "The Gusto"! Blow it AND spray it!

I’m a hair dryer fan myself, a pair of s400’s would probably work real good for something in this power range

Blowers have their place....on two cycle Detroits :sneaky::rofl: or maybe if your after that classic look. The only exception is a screw blower lol

I think he is referring to the fact that his particular blower was a shaved aluminum dispenser and ended up tearing his engine up

I think the bump in HP that they explain with nitrous is with a wet system controlled by but separate from the TBI itself

D..

That's hard to say.. you know how this goes ..hahahaha

I plan on creeping up on it until it's enough. .. its about 800 now. 15 to 20 lbs shouldn't be too much issue with gaskets either it will have a double fire ring.
fire ring in the copper backed up by oring in the block ..

I am guessing 1200 min .. someday in the distant future maybe 1800 max.

I figure that at 1500 it will be reliable as reliable gets at 1500hp.

Going past that is going to really add up in drivetrain suspension chassis.. first will be the trans. Then the rear end. While it is a Moser nodular center section ..Moser back braced housing and 35 spline axles..
I think the third member will be past its limit even at 1500

Yep...
Except the engine did survive. It passed the most of the aluminum

It was in my 69 Camaro. Here is a background to why I dont like blowers. Beside the sneezing it did when cold...
The crazy thing is when I yanked the blower with this low compression and giant cam although it had to idle about 1100 rpm and 1400 in neutral the 60ft times were still on par

514. 8.5 to 1
Solid flat tappet cam
288@ .050 .682 lift .028 lash 102 in 116
1.75 rockers
2 Holley 750 d.p
317 cfm @.600 lift heads 240
3.90 - 57 olds rear end with spool
32.5 x 14.5w slicks
11" 2200 rpm converter

10% underdriven 6-71
Boost gauge only showed vacuum

11.19 1/4 mile @119 mph


Changed to 10" Ultimate Street Fighter t.q 38-4200 stall [ more like 46-4800 with the big high comp motor ]

Discovered the belt was bending the pulley down and skipping over it ....Set blower snout pulley spacing 3" back
Still showed no boost

10.49. 1/4 mile @ 127 Going sideways

same 10% OVERDRIVEN
4 lbs boost

10.09 1/4 mile @ 131 mph

After finding out my blower was really a aluminum shaving injector

No BLOWER same motor and converter
Added Black Widow intake and 1150 Dominator
2880 lbs plus me
31.5x14 slicks

10.49 1/4 mile @ 128 mph
