Re: hp question

if the V8's of that era were getting Low to Mid 200's, 125-ish would be my guess

Maybe you should start a pool...

Re: hp question

I'll say right at 100

What do we win if we're right?

Re: hp question

If I remember the factory rating was about 140 for the 250.Since there is a loss thru the driveline I would guess rear wheel HP would be about 90-100.That is on a new engine,with everything in mint condition.Since the truck is almost 40 years old and probably has some wear maybe 70-80 HP.The formula for HP is something about torquexrpm with some other factors also.As rpm goes up if torque stays the same then hp should go up.Let us know what you come up with,otherwise curiosity may kill this "KAT".
BTW I have a 6 also.
