the only crank casting number i got(my book is 68' up only)is a 2690 casting for a 68-75 350 steel crank....check that number....the block is probably a 327,if all els fails just measure the pin height on the pistons or side by side compare them to a known 350 piston.

Your bore will be 4.060" Yes you should be able to get good torque from it, depending on cam selection. Your best bet is call Competition Cams, tell them what you got what your doing with it and they will recommend the best cam for you.

the 2680 casting is a small journal 327

as for a cam do you have any restrictions?
roller, lift,or vacuum???

i ran a 327 this year and kicked some ****
i ran a roller setup and was very happy with it but i had a vacuum rule to restrict my motor

drive hard or drive home
