Ok there is a thud. Not as strong as i would have liked. @45 psi applying yp to 60 psi. Tried pouring fluid down passage ways the air checked. I took a bath in fluid. No i didn't test fit the rings 1st. Didn't. Think of it. So it sound like i will be ok. I guess i can. Carry on. And install the valve body. And get my ptc converter ordered. 9.5 " 2200-2400 stall.
