thanks for reply. I do not want to do any sloppy work. I did a leakdown test on #8 only and had air coming fron dip stick. I assume the worse and will pull the motor remove heads and rebuild. possible I will just sell it as is and let a full time mechanic go for it.
I posted another possibility on a diff forum and had no reply as of yet. maybe u can comment:
I have access to a 94 motor home = on a chevy 1 ton chassis with a 454 7.4L V8 OHV 16V with 43,000 miles on it. hasn't been run for several years. can I pull that 454 with tranny out of motor home and put in 72 3/4 ton GMC/ what about the computer? how can I do it without the computer and what actually does the computer control on motor? Is this a practical solution or am I causing more mental duress! thanks
