Loaded Question

If I went through my engine and did the following:

Bore, Babbitt, Cam, mill Head, Webber intake kit, header, digital ignition & 12 volt conversion.

About what HP can I expect?
 
While the engine will work with the poured main & rod bearings, most folks have started gravitating towards insert beings and pressure oiling. Since it is a big 4-cylinder at 200 CID, a person could expect to get a respectable increase in horse power. The Model A & B engines were run on the dry lakes of California a lot before the V8 started to take over. The big limitation is the fact that it's a valve in block engine so most of the rodders back then did a lot better with OHV conversions.
 
In answer to initial question. It depends on which head and how much is milled? Depends on which cam? Is the Weber jetted correctly? Keep in mind. Electricronic ignition does NOT add HP. 12 volt vs 6 volt does NOT add HP.
Be more specific and you get more accurate answer, ken
 
I was looking for a general answer. I understand the variables. I know what I’m looking at doing isn’t reinventing the wheel and wondered what guys are getting.


The Model T guys were very helpful when I built my T & had questions like this. Also the LSR guys were I built my Landspeed car.

Just trying to get a general baseline.

Thanks,
Brett
 
60-65 Seems to be pretty readily achievable from what I've heard. One of the biggest issues with big HP numbers and highspeeds is getting the RPM's up. The huge Fly wheels helps with the torque.

HP=Torque(RPM)/5252

I've heard the Insert Bearing can help get the engine spinning faster-But I've also heard mixed review on longevity of these installations.
 
Type of head would help us make a better guess. If it's a stock head even with the webber and the cam my guess would be around 55.

Thank you. That is what I was looking for.

Much appreciated
