Hey guys,
So this one is a shot in the dark. I found a 1976 Olds 455 motor for approx 350 bucks w/ 69000 original miles. Of course, this motor came carbeurated. Now, since the injection on the 4100 motor is throttle body, which is essentially injectors bolted in place of a carb, some things have come to mind.
1)Does the throttle body injector housing have the same bolt pattern as a carb used on a olds 455?
2)This one's doubtful, but I'll ask anyway. Would the intake manifold from the 4100 bolt to the 455? I think probably no since the 455 is a big block and the 4100's a small block.
3)If the throttle body injector housing does bolt to the 455, would the injectors that are in the sucker right now work? I'd assume I'd need bigger ones.
3a)If bigger injectors are needed, will the computer need to be upgraded to use them correctly?
4)I figure that the computer for the 4100 is linked to the distributor in some way, to control the air/fuel mixture. Basically, can someone explain to me what sensors/things that the computer uses to control the system. Do you think they could be adapted for use on the 455
I figure this is a shot in the dark, and it'd probably just be a smarter idea to save me some hassles and just convert the car to a carb setup. But I'd like to know. If this works, it'd probably save me alot of messing around with the electrical systems in the car
