Hello, I've got a 500 cad that I'm putting into my Chevy pickup. Can anyone tell me what the Intake manifold is, a dual plane standard flow, dual plane high flow, etc.?
Are the exhaust manifolds standard exhaust, High Performance, etc.?
Also, what is a multiport fuel injection for a 1976 500 coupe d' ville worth?
I appreciate all the help and want to thank you ahead of time.
Thank You

Aftermarket 4bl intake will be a little hard to find. Factory 4bl intake is dual plane. EFI value is hard to say due to limited demand and how much of it you have. To someone needing parts to keep their big block EFI running a lot, to most others little. However intake with throttle body could be used with modern aftermarket EFI kit

slowroll,
Thanks for your help. I have the whole car with the EFI. It will run for a few seconds if I pour gas down the throtle body, but won't start on its own. Don't know much about EFI's. I wouldn't mind having EFI on my 500, but I'm putting in a different cam for torque, and maybe High Flow exhaust, etc. I was told that the original EFI wouldn't give me any better performance or fuel mileage than the stock carburator. They said that if I do any changing, cam, etc. that the computer on the original EFI would have to be reprogramed and it's hard to find anyone that can program the old style computers. Now you have me interested in the modern aftermarket EFI kit. What is that? Is it reliable? Do you think that it would give me enough torque gain over a carbutator to be worth the cost? Maybe I should hang on to my EFI for awhile. I'm building a 1986 Chevy 1-ton crew cab dually for pulling a 16,000 lb. 5th wheel travel trailer. I'm not real big on the 454 so I pulled out.
Thank you again for all the help.
