Should be 4,000rpm the 250 is the same as the 200 just bigger bore. Specs for the 200 is 4,000rpm so im sure its the same. Somebody else could probably tell you if im wrong.
Can I add any kind of power in any way to make it past 4000 rpm or will that just mess up the engine,I'm just ryna get the most out of it
You could theoretically spin it up to 7,000 all day. These six cylinders have a great valve train system. But to make power at that RPM you would need extensive head work, induction work, cam swap, exhaust work. Unless your building a racecar there's no need to spin it over 4-4,500. But if you want to..... a cam swap with a different LSA will change your power band. Not sure if the stock carburetor would support it, or even points especially if you have worn out ones. http://www.classicinlines.com/products.asp?cat=115
Is there any electronic distributor that would fit on the engine or would I have to get an aftermarket onE?
75 and up will be electronic, you will need the ignition module to go with it. The swap is very simple. I got a distributor and the module for $10 at a junkyard. And it's just as reliable as a MSD/petronix. There's no advantage with going aftermarket, you will still make the same HP as a good Duraspark system will make. Here's a link to a "how to" on the subject http://www.classicinlines.com/DSIIswap.asp#About
It's simple, the link I gave you has a diagram for it. As long as the distributor is for a 200/250 it will work fine.
The 250 has a longer stroke...thus giving it 50 more cubic inches than the 200. A stock 250 could rev to about 4500 but there is really no power past 4000 rpm.
The 250's longer stroke moves the RPM down some, 4,500 is about it, more like 4,000 .... The 200's short stroke will rev higher, I had mine up around 6,000 once, really no power there, but it went to it. I forgot which car I was driving at the time and spun it that high, that was when the 200 had a 75 shot on it! I think the 200 was shifted around 5,000, my 250 was only 4,000, but the 250 was quicker due to more torque.
i bought a rebuilt distributor for my 250 off summit racing for 38.00 dollars plus a 5.00 core they give back if you mail your old one back in ,heck of a deal
Sorry im still learing my self. If the 200 and the 250 is the same engine and the bore is the same how do they get 50 more cubic inchs?
Darren was quicker than me They increased the stroke. Distance the piston moves up and down the cylinder Formula for cubic inches Bore x Bore x Stroke x .7854 x Number of cylinders 3.68 x 3.68 x 3.91 x.7854 x 6 = 249.52 cid
