[Marty68]

Hello truck lovers.
i have not posted for quite a while. i own a 51 gmc. i got it with a 66 283/ stock suspension trans rear end. over the few years i have owned it i had suspension replaced with M2/coil reat. tremec 5 speed.
a couple months ago the 283 deleloped chronic loss of compression. i swapped it with a mild build 350.
the intake manifold is taller than the stock 283. i am having dificulty getting the solid numerous bend rod to work correctly. it at rest hith the firewall and full gas pedal depress the rod hits the head.

my question is what have you guys used? i have accuried an 87" s10 throttle cable and pedal. but mounting it may be more dificult than desired.
