I went and bought a new timing chain set for my truck yesterday (85 with a 360 4bbl) apparently the edelbrock timing chain will fit all 360's and i think 318's up till 1990 except if it has the factory oem roller camshaft. Anyone know what had roller cams before 90? I thought all the engines were normal until the magnum came out which was in like 93 or 4 or something did the magnums come out before then?

I assumed my engine don't have a roller cam and this part would fit.

 

They started with the roller cams earlier than 1990 - my 1988 318 and my 89 360 both had them. I do not however know the exact year they came out. I know people have said they cam out earlier but don't know when.

 

i think i remember reading that the cars got the roller cams a bit earlier than the trucks.

magnum 318's came out in 92 and magnum 360's came out in 93

 

Roller cams 87 or possibly 86 for cars and 88 for trucks as far I know.
That is with the 318 & 360.
