Im going to check out a 1972 chevy c10 next week with a twin turboed 12 valve in it, it has a th400 and the stock 12 bolt in it.

Any perticular areas i should check out? and will the stock rear end and the th400 be able to hold up to that 12 valve?


Heres what the ad said about the truck....


72 chevy halfton 2wd with a twin turbo cummins ddp 150 horse injectors ,5k gov springs, headstuds , full cut delivery valves, shied cam , five inch exhaust adapted to a built chevy th400 trans truck is running and driving and very quick.



I read online that the stock rearends dont hold up very well to the twin turbo 12 valves, is this true??

also, he said its leaking a little oil, not very much, and its coming from the front of the motor, its most likely the oil pan?

I'm a 67-72 fanatic, the 12 bolts are pretty tough,
but a TTC could destroy anything, lol. I had Moser
build me a set of 500 HP axles to my door for just
under $300. (Direct from them) I would consider it.
