Give me some casting numbers off the back of the block. I am pretty sure 555614 is an easy ID for a 303. Is that a Hillborn unit you have on the 303?

I'll post all my #s tomorrow after I get out to the shop. Yeah, it's a hilborn set up. It's got a Wilcap adaptor to mount a Muncie and an aluminum flywheel, 12.5/1 comp., an Erson cam...etc. It was supposedly in a '55 Chevy way back when and ran near the 10s(?), it's been on a stand in the guys garage for 25 yrs. It's fresh but I didn't have it done and didn't get alot of info when I bought it. Sorry for the long wind!!!
