Re: [T3] ? Mystery of the Clacking Valves ?

with a 1776 you most certainly have a non-stock cam in it, so you would also have dual valve springs that require

I only have the one from #3 (the bent one) on-hand, but if I'm not mistaken it feels/looks like anodized aluminum rather than steel. D'oh! :-|

Secondly, when the installed the new pushrods did they cut them to the exact
same length as the ones that were in it?  If not that could wreak havoc with
the valve train geometry and cause quick wear to the guides and seats in an
extreme case.  With a 1776, you wont be running stock geometry or stock
length pushrods.

Thanks much for this tip/alert Keith (which completely freaks me out, btw ;) I'll inquire first thing in the morning to see if they still have the other seven original pushrods to compare. If not, at least I have the bowed one, which could probably be straightened out well enough to tell if the new rods are a different length.
