I'm also retrofitting my 355 Marine motor this winter.
roller cam button & retainer plate, retrofit lifters are much longer than FT lifters requiring a much shorter pushrod, the only way to be exact is to check with a pushrod checker, Comp HE retrofit lifters, I recently found them New for $358! Comp Roller cam, found new for $243 shipped.
The bronze gears are crap IMO, especially with all the chinese grade bronze out there. Watch out for the $15 bronze gears. Either go with the Comp Poly gear or a GM Melonized gear. Crane also introduced a steel gear for use with roller cams.
I'm still not up on the timing chain issue. What would be different about the Timing chain? Will my Cloyes Hex Adj not work with a Hyd roller cam? I can see why a 87+ roller block would require a different chain but I will still be using an pre 87 block.

just tell the technical rep. ur speaking to that your retrofitting....in jegs the pushrods are labeled as {retrofit for pre 87 sbc's} so those ...aaand some roller lifters with locking bars....aaand roller rockers, of course the cam of ur choice...cam buttons are like 15bux...the bronze gear no doubt.
