![]() I bought this beast mustang but it has 351 windsor senior heads on it. I cant figure what the deal is with it lately. A horrible thing happneed so i had to rebuild the engine but the enigne then started making a thunking noise. or sometihng more like a hard ticking. It seems to be consistent with my RPM's as well. I replaced all of my pushrods and also have harland sharpe rollar rocker arms for 302 or 351(is there a diffrence?) I als had to replace one lifter. Im guessing its the lifter but i dont know why. would a stock lifter screw something up ? I dont know if the other lifters were aftermarket or not. Please help me out guys its becoming quite aggravating havin to tear my enigne apart every other day. Thanks

![]() Why in the world would you "rebuild" an engine and not buy new lifters? I'm baffled.

![]() Well actually i didnt rebuild i jsut rerings and nmew gaskets near everywehre. polished up the heads and jsut made evrything a little nicer. The motor was rebuilt just about 10,000 miles before i got it so everything was near brand new ayway thus i didnt replace evrything. and the pistons are the same. the lifter somehow scterred adn worked a spring to my oil pump and lcoked it up is what happned so i replaced it. lost oil pressure and bent all my pushrods.

![]() Well i dont know if this is your problem but i had the Harland Sharp rockers and they ticked like hell, And my valvetrain and block were completely new, I had to replace those rockers with the SVO Rockers, This solved the problem.

![]() Be very leary of used or cheaper roller rockers. I had a set of no-name-brand rollers on my Chevelle. After a few 1/4 mile passes at the drag strip, I developed a hard ticking. This was a pretty reliable motor until then...well, I gues until I added the different rockers. I replaced the higher ratio with ones of the factory ratio. I didn't feel I needed the little extra lift they were giving as the cam already had over .610" as it was (it was a big block 396 Chevy motor). One of the rockers broke a chunk off in front of one of the roller tips that rests on the tip of the valve stem. After the motor grenaded itself, a teardown revealed that the missing piece was the cause. You get what you pay for. Try not to save too many dollars on cheap parts.
