I think 4k is plenty safe for the 2F, but like I said I have hit 5k with no problems as well, but doesnt mean Ill do it all day.you dont need that, its weight reduction of the rotating assembly for a quicker revving engine.
4K is redline. That's what Toyota says is the safe upper limit of the engine. I'd say that is safe under load for short periods.
Intresting tread.
What are the thoughts on putting a blower (mechanical compressor) on a 2F. It would give more low end power.

I agree with Gumby , just trow a 1FZ and be done, I have a 1FZ supercharged Rotex (not the TRD crap) haltech engine managment, and ethanol injeccion, it puts 246hp to the rear wheels on 35¨ rubbers I am 9300 ft above sea level the stock motor put 90Hp to the rear wheels. you can tell the diference!!.
My first 40, which windowed the block on the highway and then the engine I replaced it with. It was fine, but I didn't run it hard.
My last 40. Which ran fine. I didn't have it very long so I guess that's not "any period of time". However, it did sit in a swamp for more than 10 years and I was able to start and run it without taking the head off. That doesn't really speak to the high speed reliability of the engine, but it was pretty amazing.
My 60 had the engine replaced once, then the owner gave it to me when the second engine seized on the highway. I put a small block in it. It didn't have any more crank failures.
My 55 had the 350 put in because the previous engine windowed the block on the highway on the PO.
My 45 and my second 55 had 327s put in as well, but there are a lot of reasons to change a F. They might not have blown up first. I don't know the history of those.
I've had not a few customers who have also had high speed problems.
Besides - I have never had an early Norton bike, but I understand the physics of why the crank flexed and broke. Does it mean that it never happened because I never owned one personally?
moates makes a much easier program IMO.
I used it to program a 7747 GM computer to put a 4.3L Throttle Body on a 2.4L 22r(tbi!).
Works great. Would work even better if I used a 2.8L throttle body. I get 17-18mpg with 37's! Which is consistent with my stock 02 taco.

Everyone has seen this. But it's fitting for the thread. Fairly stock 2f with TBI.

It's easy to find dead 350 pics on the interweb.
I know more people that have failed chevy motors than have had failed cruiser motors. Hell, I know of a BUNCH of 350's that never made it past 130K. Perhaps that is because they were used. Perhaps it is because the quality control was nonexistant for chevy for a while. Donno...
So, how many months have you actually owned a Cruiser straight six?
I wonder how many million more sbc engines were produced that cruiser sixes?

Here we go again, both are excellent engines, the Cruiser six is a half a million mile engine, the SMC for the most part won't go that long.....however the LS engines will.
There's no question that SBC motors are of lower build quality than Cruiser motors. How does that have anything at all to do with spinning a 2F faster than it was designed to be spun? Or in the inadvisability of building a motor designed for trucks in the 1930s to make huge hp? It's simply outside it's design parameters. Doesn't make it a bad motor, just not built for that purpose.
CSB are also cheaper, easier to find, a lot lighter, make more power, are stupid cheap to build and rebuild, you can find parts at Wall Mart and there are easier FI options. Makes them a good alternative if you want more power at the expense of longevity.

But the new LS motors are lasting, we see them in the shop all the time with 3-400K and still going strong, with no issues. This is why they are cheap at wrecking yards, they are not getting to sell to folks as replacements.
I think you answered your own question.
I drive this computer everyday and have for years, but I'm not qualified to answer the question if it's safe to overdrive the processor.
Do you really want my resume on automotive experience?
And I daily drove a Cruiser straight six for about 7 years and 100,000 miles in addition to the Fs and 2Fs I've owned.
