13 sec. 360 for $3,000?

I did this in the seventies. I bought a low mileage 360 (6000 miles) but it had a split bore. I think I paid about $300 for it. I was given a set of second hand 340 pistons so I sleeved that bore then sent it 040 over and fitted the 340 pistons! My dad being a pre war motorbike racer and tuner forbid me to use a reground cam as he said it destroys the valve gear geometry and said I could only use a billet cam from the states but in those days it took a long time to get any thing. So the standard 360 cam it was but with the high compression of the 340 pistons. I was an eighteen year old apprentice so money was tight so I did a bit of clean up of the ports on my 360 heads and made my own headers with an oxy torch and stick welder and dual exhausts. Car was about 3300 lbs with 4 speed manual and 323 diff and ran mid 13 sec qtrs @ 102 mph straight away. I think It never cost more than about $500 to build that motor back in the day and was considered fast for a street car of the day and idled like a stocker.
