So, I just bought a 543...

I’ve been looking pretty hard for a big block stroker short block and happened to stumble upon a complete 543” stroker with not much time on it. I felt it was a pretty good deal and I jumped on it. There is one aspect of the engine I don’t like, and that’s the choice of heads this person used. He had a set of Edelbrock E-Street heads on it. Even with those, I felt his asking price was more than fair. After doing some digging and a call to Edelbrock, I found the casting for those heads and the RPM heads are the same and it’s just the hardware that’s different between them. After searching countless threads, it seems this engine almost should even run with those heads. Yes, I’m being a little sarcastic. I have a set of RPM heads on my 440 that I was thinking of swapping over, but the threads on here seem to say it’s a waste of time.

Here is the build. Please give me your thoughts good, bad, and/or harsh.

-The rotating assembly is from 440source.
-The cam is a solid roller from Hughes. Lift is .632 and duration is 256°.
-Cylinder heads are Edelbrock E-Street, untouched from the box. They do have dual springs installed. The rockers are 1.6 Hughes
-The intake is a 4500 series Mopar M1
The guy I got it from ran it on alcohol.

My thought, as I mentioned above, was to toss my RPM heads on it along with my RPM intake and a carb and call it a day. Bad idea? I’d like to get a set of Trick Flow 270 heads and an Indy intake, but as we all know, the heads are a couple of months out. I talked to them today and they said it’s the valves they are waiting on. I’m not looking for a world beater.

Anything I left out? Questions? Concerns? Complaints?
