Help with a new to me 408
hold downs don't look too bad honestly. it's not like they were precision machined from the factory. i'd dress 'em with a file or some paper so there's no high spots or potential places to snag or gall and then shim everybody tight and ship it.
time for a new cam. with a stroker... why not go solid roller? *evil laughter ensues*
x2 on furry's advice: clean everything and then, when you think it's clean enough, clean it again.
