    How quickly should oil pressure come up?

    It seems like the oil pressure on my 318 "comes to life" later than it used too and I'm trying to decide if I should be concerned or am just worrying too much as usual. On a cold start or a warm start after sitting for an hour, it will take 2 - 3 seconds for the mechanical gage to come up with...

    Intake oil leak

    I know this has been covered before, but thought someone might have recent experience. 318 with Edelbrock Performer. After about 600 miles, leaking at china rails, front and rear. I used Ultra Black rtv but maybe not built up high enough? No issues at all with the intake to head gaskets and...

    Oil pressure concerns

    1974 318. 40000 on factory bottom end. Running Lucas 10w30 with Wix filter. 4 extra holes drilled in oil filter mounting plate. Oil pressure is 65-70 cold and 50-55 cruising at 2300 warm as per aftermarket gauge. The two concerns I have is that pressure at 800 rpm idle with 190 coolant temp is...

    318 passenger side manifold heat riser?

    Does anyone know if all small-block manifolds came with a heat-riser valve from the factory? Engine is from a 74 Valiant 4-door originally sold in Mississippi. The manifold appears to be cast to have a heat riser but there is no spring or counterweight and I can't see any evidence of a shaft on...

    How much free play should new timing chain have?

    So I slid the new double roller timing set on the 318 and it has 1/2" of slop. Sealed Power KT3-160S that claims to be made in USA although the bag the cam sprocket was in said Taiwan. The chain does say USA. I was expecting a new chain to to be tighter than that.

    Used cam wear pattern

    Finally doing the timing chain and adding 4 barrel to my 74 318. Engine is currently all original with 42,000 miles. I may just be paranoid, but I think the wear pattern on the cam lobes looks funny and some of the lobes have what look like a dent or chamfer on their edges. I may just be...

    318 driver - cam change or not?

    73 Duster 318/904/2.76 gear. Rear tires are 225/70-14's. Just have a 7 1/4 rear so no tire-burning. I am primarily interested in around town punch and am trying to decide if I want to change the stock cam or leave well enough alone. Engine bone-stock 74 318 with 40,000 original miles. I...
