Vintage Ray Jay Turbo ???

Not much availible for the IH stuff that is anything but stock. Start by getting it pulled apart and cc the heads for combustion chamber. I presume your existing engine has flat top pistons and d shapped chambers. If so the stock pistons by silvolite cam de machined to creat the required dish. Just maintain a crown thickness of .200 minimum.
 
Ok it's been a while and here's my update. I have purchased some nos pistons that are made for lpg. Even if these won't work for what I'm trying to accomplish they'll still come in handy.

The part number is tc1895 and they're .040 over.

Ok I've run in to a dilemma. The pistons I've bought are too tall, even with .200 taken off the top. The piston is stepped crowned so it wont work. It's like this piston is supposed to have different heads. So back to the drawing board. This is a pain in my arse....:confused5:
 
If your engine serial number has an e in it you need the flat top pistons. Also look at the combustion chamber shape. If you see a general "d" shape where the deck overhangs the bore along one portion, you definitely need flat tops.

If it is basically round you need domed ones like you have.
 
Yup the heads are d shaped. I have some flat ones by silvolite ready to be dished. Thanks mr kenny for your help.
