Hey all -
Finishing up fixing my V8 conversion (Gen 1 283 SBC) that my PO had butchered. I stick mostly to the @Downey conversion manual, but I've run into an (anticipated) issue clearing my power steering pump.
Common wisdom says to mount the engine 1-1.5" toward the driver's side to allow for optimal driveshaft alignment. However, I'm going to run into a problem with this side-to-side adjustment.
Below is with the engine "dead center" between the frame rails, with the crank center at 12.25" from both frame rails to the crank about. This allows for full outward pump adjustment -
I'm trying to figure out how running the V8 centered will affect driveline angle. To the naked eye, this doesn't seem too bad:
There's definitely a BIT of deflection
Is there a good way to measure the "side-to-side" angle of the driveshaft?
I used an angle finder on the pinion flanges and the vertical alignment is good (within ~2 degrees of parallel) but I'm not sure how to measure the deflection from side to side.
Is anyone else running the engine centered? Will this result in bad driveline vibrations?
The issue is, even at 1" to the driver's side, I lose about 1/2 the adjustment on my power steering pump. Below is the max adjustment with the engine 1" to the driver's side:
In short - where do I make the compromise? Not sure that's enough steering pump adjustment to be able to install and adjust a belt, but I'm not sure how to determine if I'll have driveline issues if I run the engine centered. Are there other clearance issues on the passenger side I need to consider?
