NICE 520 Street Dyno

[Chad Speier]

249/257 HYD cam 520 cid street Mopar with a set of CNC Edelbrock RPM heads, (v.2.60/EDRPM). Guy is HAPPY! Nice 1000 rpm of 600 street driven horsepower!

That is going to be a riot to drive.

What the LSA on that cam? How's it idle?

Hey Chad, nice to see Ya here. Do you have any eye candy to post?

SURE! What would you like?

Cam card

That must idle great. It also explains the broad power curve. I really like that cam.

I'm surprised they added duration but not lift that exhaust. Not that it probably matters much but it's uncommon to not see both.

Oh, IDK, how about a general engine shot with a small general list of parts that went into it? Like the carb and it's specs, intake used, compression ratio, etc.
B or RB engine?

 

[Chad Speier]

I will see if I can get that info. Most of my end results is just dyno sheets and phone calls. I do have head data though!

Also looking at PipeMax, it was getting all of the head.

That should be a beast

Chad,

Cool build.

Hope you get your money from those worthless scumbags in Detroit!
