my 88 4-v 360 headed 318 had a double roller chain,roller block/slider cam,windage tray,oil cooler,tranz cooler,ps cooler

the oil cooler return line use a hollow fuel pump bolt to dump oil back to pan and sprayed the roller chain

for longevity I would think

I just swaped in a lunati roller cam and stock valvetrain gear

never had the heads of it yet and is still a little screamer

is getting a little tired though

well over 200,000 on it now
