I have a 1975 Cougar XR7 with a 351M and a C4 (it has the big bellhousing).

I am almost done rebuilding a 460 for this car. I was going to go with a C6, but after reading the excellent C4 monster thread, I am considering rebuilding a C4.
I read that the C4 can handle lots of horsepower, but my car is being built for towing. The 460 will put out 500+ ft-lbs at low revs pulling a total of 7000+ lbs, which is not quite the same as 500 hp at 5000 rpm in a 3500# car.

I have located a E2T code C5 that I can pick up for $200 Cdn.
Would it live?
