Hopefully the post is ok here. Ok so bought a 1974 Cuda 318 LA with a 904 transmission. Everything is stock in it and was rebuilt a few years back but every thing stock was put back in. I am planing on putting this in a 1956 Fargo. I took the 2 barrel intake off the other day and the heads just to see what I have. There is no sludge and .030 pistons. Now I have been looking at cam kits that come with the cam, lifters, springs and timing chain. The timing chain is single not double. I do have a question. My buddy is somewhat of a mechanic. Works on a lot of old cars. Keeps telling me to get double roller timing chain. I am not going to be racing or anything like it. Do I really need one? The cam kit I have been looking at. https://www.summitracing.com/dom/parts/cca-k20-221-3 I have also seen on here about mild cams. What would be considered a mild cam for 318 LA motor. Now for intake. I will be getting a 4 barrel intake. Maybe Edelbrock Performer with a 650 carburetor or a Weiand Action+Plus with a Holley 670 Carburetor. Both intakes are dual plane. I will be using my original heads for now. Not sure with the Edelbrock performer if I will need 340 heads. Think I read that along the way. Any help would be good thank you in advance.
