It matters if you are discussing the amount of dead sbc versus the amount of dead 2fs. If you said "percentage" then it wouldn't, but you didn't say that.
That's exactly what I was trying to do.
In my opinion, the 2F is unsuited to high RPM due to inherent design flaws. The 4 main bearings, the wet intake manifold with very unequal runner length, the suspect oiling system etc. It is a very good motor for what it was designed for.
In my opinion, it is not a good idea to spin a 2F at very high RPM. 5000 sustained. 6000 peak. Whatever.
In my opinion, it is not going to be easy to get high HP out of a 2f "on the cheap". As with all motors you will trade reliability and longevity for power. All motors are different at what extent you trade one for the other. In my opinion, the 2F will lose a lot of longevity for rather poor hp gains. Compared to, for instance, a 2JZ or 1FZ.
And even though it's not what he asked there are better ways to spend your money, again, in my opinion.
If it matters at all, as with Butch, it is a professional opinion.

I don't have a dog in this fight, I like, own, and appreciate all three of these engines.......and will do what ever my customer pays me to do, sometimes instead of my recommendations.
Oke we know 2F engines don't do well on high revs for long periodes of time I come back to my question, did anyone try to put a blower (supercharcher) on a 2F. I have a Mercedes with one and it gives a lot of power with low revs. So is there any reason not to try it?
How do you determine the volume needed and how much extra power will it bring?
I have no clue to tell you the truth.
My T4 Turbo works well. So I would assume that a reasonable amount of volume at lower pressures would be beneficial. Nothing over 12 psi.

me too, well with the exception of the LSX series (dont own one), but they are all great options. My 2F's have served me well thus far one will be getting a 2F-E when I have some more free funds to finish it then it will eventually (maybe) see a SBC on pane and maybe someday a nice 5.3 or a ls2 or (in my dreams) an LS9 (deep deep dreams)

Not trying to compare a 2f to anything . I was just trying to find out if I could make more power out of a 2f ? I have a cruiser w/ a 5.7 vortec in it and I have one with a 2f in it . They have similar setups as far as suspension and gearing and I find that the 2f puts the power to the ground better .My cruiser with the 2f outperforms the other Imop. . I find it's smoother and the power curve works better. As far as power to weight , its a bit on the heavy side . I know there is a direct correlation between the two but if I could get the numbers I already spoke about with some semblance of reliability then I might be willing to try it for the project I have in mind . I have abused 2f's a lot I and I have a certain respect for any machine that can take that much abuse and continue to perform .
Thanx, I think I will dive into it when the first one is on the road.
He does that every time he wheels it...
Yes sir, yes you have... To say "abused" is an understatement. That truck has run spent more time with the valves floating than idling in the bush!

So I was talking to a buddy of mine today and he said he might be scrapping a bonneville w/a 3.8l supercharger . Thinking that it might work . I don't know that much about superchargers . Wondering if you can lay them on their side ? Also wondering how important it is to have even length intake runners ? Anyone tried this before ?
Depending on type of supercharger, greased by engine oil or by own sump, you can put it on it's side. And you would want to put in an ajustable blow-off valve to controle the pressure. basicaly it is a crankshaft driven turbo where a turbo is driven by the exhaust pressure.
It should be about the right size for the 2F engine, find out what pressure and volume it delivers.
post some pictures.
Uneven length runners means the air and fuel are going to enter the cylinders at different velocity, volume and fuel saturation. It'd be very important that 1 and 6 don't run too lean even if that means 3-4 run too rich. Especially under boost and the additional heat generated by the supercharger. Keep an eye on the #1 and #6 plugs for sure.
I think an equal length, dry intake would generate better hp and torque as well as less detonation and carboning, but I don't know if it'd be worth the considerable fabrication that would be needed.

All this is kinda like me at 55 training to compete in a bicycle race against the best in the world, no matter how much I try, and how hard I work, and how much money I spent....
I would still come in dead last.
Hey, cool, I'm a 2F, torquey, strong and rock solid reliable.

Some people would also say that putting a gas turbine engine in an airplane built in the 50's would be not such a good Idea either but I fly in them all time .
Not everything is a race sometimes you just want to do something different. In theory a supercharger would be perfect for offroad use.
That's a roots-type blower. It would take some serious fab work to get it to work on a 2f. What you want is a centrifugal supercharger like a paxton or a vortec.
