Anyone run a Holley 670 street avenger on a Ebrock performer RPM? Also, is it possible to do a accurate compression check with the motor out of the car by rotating the crank with a breaker bar? I forgot to do it before yanking the motor. (using the starter)


Information overload!




I doubt you will get anywhere near enough rotation speed to get anything remotely accurate . I would do a leakdown test but even then a little heat in the engine before hand would have been nice.

Is the engine original or has it been rebuilt ?




When I put it up for the winter there was a tick from the motor, I thought I wiped a lobe. I yanked the motor and there is evidence of the motor having been apart. (newer gaskets etc.) So far I pulled intake and found no damage and it is really clean. I probably have a collasped lifter. I will be pulling the heads and pan soon so I will have more info soon.

Thanks John.

I've ran 4 different carburetors on the Edelbrock Performer RPM with the XE262H cam, headers, 2500 stall converter and 3.73 rear grears. The Eddy 750, Eddy 650, Holley 670 and the best one, the 3310 Holley 750. I never could get the Eddy 750 tuned the way it should have performed. To me the 650 and the 670 were too small, not enough punch off the line and not enough top end. The 3310 Holley 750 was and is perfect.





Sounds good, my choice is getting easier, thanks for taking the time to answer my Dumb ar$e questions.



Keep in mind that with that little XE262H cam the Holley 750 worked so will for me was because of the headers, 2500 converter stall and the 3.73 gears. If you're gonna run stock manifolds, converter and 3.23 gears, the 3310 Holley 750 may not work as well as the 650 or 670 carbs. But, the 750 Holley is forgiving and can be tuned for so many different engine combos!

I didn't care and still don't care about gas mileage, only performance. Just saying.

Your questions are not dumb. EVERY ONE has to learn.

Did you rule out an EXHAUST LEAK ??? This can sound similar to a lifter tick .

Look at the manifolds closely , they are usually warped. Were there gaskets between the manifolds and the heads? Also you can have a leak at the heat riser that will tick .

I was only briefly able to check it out. There were gaskets, however when I pulled the passenger side 3 of the bolts were loose. (not the ones going into the water jacket)

3 of what bolts ? ALL the the exhaust holes on stock iron heads go into the coolant jacket.
