Default Which Aluminum Intake

I am forced to rebuild my 68 L79. I want use a aluminium intake. I also want to keep the oil fill tube on the intake. Any suggestions on what spreadbore intake to use. I do have a line on a Z28 intake but was curious if a modern one flows better.

If you want the oil fill on the intake, the Z/28 intake is the best one GM ever made.

Need to carefully verify the hood clearance whatever intake you choose.

What hood do you have? If its an L88 hood the Edelbrock RPM is the best flowing dual plane on the market and you can drill the pad for an oil fill tube. THe EPS has the oil fill option as well and it fits under the stock hood. It will flow somewhere around the Z28. I had and old rightup on intakes...I'll look for it

heres a story on the fill tube. I used a hole saw and tested the size on a piece of wood and used black RTV on the inside to seal it

If you are keeping the spreadbore carb (Q-Jet) the only options you have are the 2101 Performer or the 7104 Performer RPM O-Jet....bot have a boss for the oil fill tube that can be drilled out.
All the other intakes including the Z/28 intake are square bore. I do not recommend that you adapter the carb to the intake either....defeats the purpose of getting a better flowing intake.
