We have 98 . That's it

98 in Belgium is equivalent to 93 octane Pump gas here.
Shell Brand is best I can buy here at the local gas stations.

I do have E85 Ethanol 105 RM/2 fuel local at 2 gas stations 9 miles away.
Local airport for Aviation 100 LL Gas.
Can order 110 Race Fuel by 55 gallons drum at almost $10 per gallon.

AV aviation Fuel is $6 per gallon last I heard.

E85 is $2.00 per gallon here usually.
 
So you must follow Grumpys Formulas.
Not so Bad.

His Super Stock Race Cam in the other thread looks like RACE FUEL REQUIRED.
100-110 MOTOR OCTANE.
RACE ZONE RPMS TOO.
Wont last long on 98 Europe gas.
 
if your willing to use an old school flat tappet solid lifter cam,
Id suggest a crane 110921 flat tappet solid lifter design,
obviously you can't reasonably select the right cam for any application,
without matching its intended valve timing to the application,
and other components to be used.

read these links,
yes it will take you a week or more to wade through the links and sub-links,:facepalm:
but it will also save you a great deal of wasted time and cash you might otherwise waste:like:

you can start with this, the SIX cam manufacturers POSTED OR LINKED BELOW that have proven to be dependable, the soft ware below might prove useful, so use it to get a base line INFO YOU NEED IF YOUR selecting the correct cam for YOUR combo FIRST!!>>>>>>ANY AND ALL CAM MANUFACTURERS WILL need...

a cam like this will come very close to maximizing the port flow on a fuelie head,
on a properly designed combo in a 327-400 sbc,
but its not ideal for a daily driver style cars engine application,
as its designed to operate in the 3500 rpm-about-6800 rpm power band,
in a engine with properly matched drive train ,
and other matching engine components,this was a very popular upgrade in the Z28 engines, back in the late 1960s-1970s, and more than a few competitive circle track engines we built back then.
but it can help maximize those heads power potential.
obviously youll need too check clearances, compression, and valve train geometry.

that was a very well respected cam , used in the 1970s-90s
it made very respectable power,
its best with 10.5:1-11:1 compression and a dual plane intake like an edelbrock air gap,
and headers with a low restriction exhaust,
get the static compression down at 10:1 and degree the cam in strait up, you should get by with that 98 octane fuel.
and you'll want a manual trans or a 3200 stall converter and a 3.73:1 -4.11:1 gear,
most guys used a holley 750-780 cfm carb.
with 1.6:1 roller rockers and decent long tube open headers
,it' valve timing about maximized the power OEM, Chevy fuelie heads had available in most sbc engines

before you ask.
yes theres a similar version in a hydraulic flat tappet version, you get easy valve adjustment but it costs you a couple hundred rpm in peak power, and neither versions going to be ideal on anything but a serious performance car with the correct matched valve train, intake,headers,gearing etc., remember this class of cams is designed for road racing and drag, racing and serious performance with matched tires, suspension , gearing etc where youll rarely have the engine spinning under 3500 rpm

What Pistons do You Have ?
Flat Tops ?
Dished ?
Domes ?
Brand ?
Part Number ?

Measured Combustion chamber volume ?
Calculated measured quench area ?

What connecting rods ?
Stock 400 Chevy ?
5.700 long ?
6.000 Long ?
 
I don’t thing his original question has been addressed and neither has he stated what the intention of the motor is.
The victor jr is an open plenum 3500-7500 RPM manifold
The torquer 2 is also an open plenum but intended for a lower RPM ranch 2500-6500.
Both of them would be a hot mess of goo on a mild motor that can not put out the RPM.
My 2¢ is you should find a factory dual plenum intake and use the lower RPM it gives to.

Cheers
 
The piston pin passes through the oil rings 400 Sbc on 6.000 inch center center length Rods.
I would only use JE Or Custom Diamond brand pistons- Michigan USA made .

5.700 center to center get by with lesser $$$ cost pistons.
 
I just wanna see see what we get out of the block.
With all the parts we have.
Then just see what works to put in my 72 elco.
 
If you want to have a software simulation to compare with the dyno, I will need the following. A few
things I can guesstimate and I will give you those details if I do.

DynoSim5 Input Variables

CID Or Bore & Stroke
Rod Length
Heads with flow numbers
Valve Sizes
Intake Manifold Model
Carburetor Size or EFI
SCR
Header Tube Diameter
Cam Card
Cam Installed per Cam Card, or Retarded or Advanced
Rocker Ratio

Grumpy found and posted early SBC Fulie Heads/ Famed Double Camel Hump Flow numbers.
See if I can find.
 
:confused:simulation software is nice so you want max effort on a stock internal stock fuelie head? You know the max lift capable on those heads do you plan to change springs out? (Prefer #s in inches) Are you planning to spend time opening the heads up? Or just minor clean up quick throw together? And also all the other questions asked from every one else. Junk info in junk out good info in good info out!!

I Will be asking you for your software later. Hardware and measuring first
