Hi there yoll once again. Could somebody help me, i have been on hear before ref. a 454 chev big block 96 model which i had placed in a 27 ft cruiser, the old engine was replaced with a new long motor but all my assesories were put onto the engine being the rockercovers, inlet manifold etc. Then...
Can anyone tell me, my 454 chev big block has been running rough, since i put it in my boat.<br />Now in no. 4 cylinder there is a broken pushrod, and in no.8 cyl, the push rod went through the rocker. The guy i bought the motor off told me that these 2000 model mark 6 motors run longer spark...
Ive put in a brand new 454 and it seems to be running really rough. Ive checked the timming over and over. Everything is new. Can a car pick up in the sump give you less pick up than a marine one?
