Supra is dead....

[Isphius]

Rebuild/Turbo conversion would be your cheapest and easiest. If you want the car back on the road....go that way. And supradaddy, i have a lot of experience with chevy motors/v8s...ive never seen any one of them with a cam/lifter problem. Except for my dads camaro, throttle spring fell off and it ran at 8500 rpms for about...25 secs. Thats how long it took us to open the hood and pull the spark plug wires out. Of course he ghetto rigged the ignotion with no key cause he couldnt find it, so we couldnt shut it off..But the motor had a blown head gasket, a spun bearing, and one bent push rod. Not bad for the abuse. Thats the only time ive ever seen a motor with a cam problem. Unless of course your trying to make it run in high rpms with low rpm spings/valves/lifters, then you have a problem.
