hey guys, i'm new on this forum. i've got a 1981 trans am with a chevy 305 (LG-4 150 hp) from 1984. Could anyone tell me the stock camshaft duration and sizes? Thanks!

if im not mistaken the 305 cam was 184 int and 194 ex. The 305 HO cam was 194/204

Yeah - it was right around that... dinky and not good for much.

Are you looking for a replacement cam? If so there are a lot of stock-ish cams that will work a lot better

that's exactly what im planning to do. i have an edelbrock 3702 camshaft (194 intake/ 214 exhaust) still in the box. i chose this one because it is the one Edelbrock suggested to use with the CCC (computer command control) that started being put into GM car in 1981. i just wanted to make sure it was different than stock, haha.

this is the one:

I'd check and see if the Performer cam at 204/214 won't work for you??

I bet it will do fine..

Summit sell's it and a new set of lifters for less than a "C"-note!!

If you already have it, that one will work fine and pass smog. The extra exhaust duration will help a ton
