79 Elcamino With a 267 engine want a bigger cam in it?

Answer 1

I'd bet if you called the cam manufactures they would recommend a lower duration cam of about 256 degrees of total duration and lift of about .440" or so. That little engine

will respond real good if in good shape. Don't get with a wild cam as these little engines respond well around these specs. read up and explore, think about a 350 as it costs the same to build, but for around $250 a new cam, lifters , gaskets and probably timing chain up grade would do wonders for that really small block. Be sure you know how to pull the harmonic balancer and change the crank timing gear. Know that you need to pull the oil pan as it is mated to the timing chain cover and maybe buy you a 2 piece cover so if you want to change cams later you wont have to pull your pan again. Be sure you know how to pull that distributor and line it back up on top dead center and pointing at the right cylinder. you will need a puller for the balancer and you might need a lifter puller if those old lifters are stubborn. Read up on these things real good and have your cam break in lube as it is a must. Be sure you know the difference of duration at .50 and advertised duration as advertised duration is usually total duration and that is valve lift off valve seat or open. Enjoy your motoring my friend.
