Crate motor vs. rebuilding DZ 302...?

Sounds like you put alot into the restoration. If the goal of restoring it was to show it then put the 302 back in it, if it is for driving alot, save the motor(it has to come out anyway) and use it later. There are some GREAT crate motors these days. If performance is what you want, the 302 will dissapoint IMO compared to a great crate motor.Good Luck

Every engine builder I've spoken to makes me aware...within minutes of starting the conversation...that it would be much more cost-effective to buy a crate motor and you're right,the choices are endless.

I am torn though because the beauty of these cars is winding them out.We all know there is no torque or power below 4-grand.But from 4-8K,hold on to your hat!
On the other hand,most of these crate motors are all in by 5500rpm but I guess it doesn't matter if you've got 500 lb. ft. of torque by 4-grand!

This car is built to drive not only on the street but occasionally at the track.And it will never will be sold!

John, When you restored the car didn't you redo the motor? I am hard pressed to believe that a good machine shop/engine builder can't get you running in a few weeks to a month. If the car is that nice, just rebuild. If you feel the need to go fast, Do what Darren did buy a 72 or whatever camaro that needs some TLC work with a BB for little money and go drag racing! No matching anything. I would keep the 02 in your car. JMO Sam

Sam,

Bought the car used of course and the motor ran fine.Just checked the compression and everything was in specs.No leaks and didn't use any oil.Just added roller rockers (Comp Cams chrome-moly 1.5 ratio)and a Proform mechanical secondary 750 cfm race carb and only ran it for about 15 minutes in this configuration.About 6200rpm,it decided it didn't want to run anymore and exploded.I have revved this motor well in excess of 7-grand without any problems.

Shouldn't have happen at 6200,I'll tell you that.

I agree it should not of blown. Maybe a bad cam from the factory? Might have a warranty issue there?

If that is the original motor, take it out if your driving it!!! You will blow it up again eventually doing 6-7 grand on the tac alot. You got a lead foot man, which is cool, but honestly it will blow up again from the sounds it. Not worth the risk IMO, because if hot rodding the car is what ya like (me too), then get a better/faster motor and drive it like you stole it.

A crate motor is starting to make more sense everyday,let me tell you.And since that $$$ is burning a hole in my pocket,picking up the phone and charging it to your card is TOO easy to do...

[Stuart Adams]

Good idea.

[musclecarjohn]

That's how I'm leaning...
