High performance 12a's and 13b's
I am considering building engines to order, and wanted to see whether there was any demand for stock and high performance 12a's and 13 b's.
Stock could range from a basic rebuild (reusing anything in spec, just new gaskets, apex seals, and springs) to a brand new stock rebuild (remanufactured housings- cheaper than brand new stock and garunteed to last 4 times the life of stock housings- lapped and nitrited side housings, new seals and springs, etc). These engines would carry a nice warrenty and would be done at a more competitive rate than the other professional engine builders. Because of the various range of engine rebuilds, price would have to be given when told what is wanted.
High performance would range from basic street port to purpose built race motors. Built 12a's for high output is no problem, I found (the hard way) what is needed to be done in order to make a reliable engine with high output. I have never bridge ported; however, and do not want to learn on a customer's engine, so I wont offer that service.
Please, reply if you are interested, and ask as many questions as needed!

I saw your 12a race motor for sale. Looked like a nice motor. Had all the parts I put in mine. Its a good deal at $3k. Is that one still for sale?
Put me a price togeather for a full race spec street ported 12a. Balanced, hardened stationary gears, racing oil pump, regulator, 3rd gen side seals, race bearings. (with core or without)
To be sucessuful you just need to gain a reputation. There's not that many people rebuilding these motors.
