Hiya,

I sure hope there,s someone who knows what i'm doing cause I know I'm not.
My neighbor has a 50 Ford custom that I convinced that I can take care of the build on. Mainly it's just gonna be a regular fluff up but with machining done in all the right places. I am convincing him to add a few speed parts too but nothing too radical. Well, so far.
I'm kinda stuck on how to pull the front crank pulley without damaging it. It's not a balancer but it is keyed onto the crank. No holes for a puller and using a regular gear puller may damage the pulley itself. I feels like it friction fitted on good like a balancer would be. Any ideas?
Also there's an oil pump idler gear in the back. My best guess is it pulls off with a slide hammer at the stationary hub the gear rolls on. Am I right? Also, is it necessary to even pull that gear off? It's recessed into the block anyway.
Another thing is my neighbor mentioned that he'd like to convert the car from a 6 volt system to a 12 volt. How involved would that be? Has anyone done it?
Another concern is the car will have a 3/4 race cam installed. The problem may be the owner wants the aluminum heads that have the same chambers as the Mercury heads they had in the day. It don't look like there's much wiggle room in the combustion chambers as it is. Will I be looking at valve clearance problems?
Any other pitfalls I'm not seeing I'd appreciate being made aware of. Thanks
