Carb to TPI Problems

[madness410]

So at the swap meet i bought a TPI set up for my camaro and would like to switch the carb out for the TPI. The only problem is my cars engine has nothing in it that is stock, the main problem that stands in my way is apparently the knock sensor, the kind of cam thats in there right now I was told would not work with the TPI set up. I was told if I want the TPI the valvetrain is going to have to get rebuilt, new lifters, cams, valve springs, heads, and possibly rockers....so basically everything, because of the knock sensor.

Does anybody out there know of a way to bypass the knock sensor...the last thing i want to do is switch the cam in that engine...

any advice or help is greatly appreciated..thanks guys

You obviously didnt understand our conversation on the phone.... I told you I can disable the knock sensor but there will be no protection against detonation. Therefore, we will have to back the timing down earlier and your mileage and driveability will suffer. If you are running a noisy mechanical flat tappet cam you are probably sacrificing power anyway. Technology has come a long way since 1969, take advantage of it. Also, the motor oils produced today do not have the same properties as they did when flat tappet cams were the norm, this has reaked havoc with cars still running that type of valvetrain so you would be eliminating that problem before it starts. You are obvoiusly trying to add driveability and mileage by converting to F.I. if you take that benefit out of the equation, all you are doing is giving up hp and adding aggrivation and extra cost to your project.

The oil thing is a big deal. Zinc has been removed from today's oils so they don't work properly with a flat tappet cam. The only ones that I know of that still have it are Castrol Syntec (for classics) and Rotella T. Or you can add a can of break in lube at every oil change.

Edit- Josh that was not directed at you, I was just quoting your post.

hey sorry josh..this was a simple case of misunderstanding. the person you talked to on the phone was my mechanic...who practically built the car. he didnt relay all the information to me but simply told me if i wanted the tpi on i would have to alter most of the valvetrain, and didnt tell me that drivablity and mileage would suffer if the knock sensor was disabled.
