There should be a "DZ" on the engine ID pad.

My buddy has a DZ in a stock Z28 69 camaro. It is all top end, good rpm's, torque is not is finest attribute for sure... has to spin the tires to get a decent launch, but it is all stock w/ the solid cam & 373's. Neat motor, but needs low-end assistance (his car is 4spd). It is a dog until about 4500RPM then it gets it.

its in around a 2000 lb car with me in it but i was told it had a eagle forged crank and a .5 something lift flat tappet but it does have roller rockers and a rpm air gap

Whatever you do don't swap it for a 302sbf!!
That would ruin the property value of your house and you neighbors too!!!!
Heard of 'em but never messed with one.

never would i swith out anything for a ford motor its always a chevy

the short stroke works well at high rpms. You must have a good set of heads, cam and carb to make something light go fast with a 302. Your .500 cam is way to small. Drag racing these 302's you want to turn them atleast 7500
