Re: 350/255HP Help please
If its a junkyard block 384 is not that bad,if its leaking more than 6% you got problems, Call Greg at race rings get his ringpack give him the grove dept,and he will fix you up get it honed with a plate . Cam should be in at 103-104 with a three speed.spring pressure around 145 -385 with reg lifters. Bowtie should pick you up 20. good luck.Not all dynos are the same.
