Engine: Hydraulic-cam 350 delivered 185 bhp and 280 ft./lb. torque. Cast-iron crank. 2-bolt mains. Cam timing: 280 degree intake, 288 exhaust, 58-degree overlap, 0.410 inch lift. Rochester 4-barrel carb. No mufflers but after the single catalytic converter the exhaust system split into two resonators and dual tail pipes. Identical to and unchanged from 1977.

Re: looking for specs. 78 z28 camshaft

didn't that motor- and pretty much every other small block of the era besides the 350's in Vettes- have the trusty old .390/.410 cam in it?
if so, it is a great cam for a daily driver that you wouldn't mind getting 25-30 mpg out of.

you don't plan sincerity.
you have to make it up on the spot.

wanna hear about 20 years ago when i was too smart to know any better?
