Tonight I went a bit deeper into my motor - pulled off the pan and vc's - and, as I learn more about the FE motor, I think I have finally found the problem as to why my car seemed kinda sluggish from idle to 5000-5500 rpm, and then goes like it's been shot out of a cannon until the msd cuts it off at 6000. Not that it wasn't fast, just that it wasn't fast.... - it was real fast for that last 500-750 rpm, but....it was over pretty quick

Here is my theory - comments appreciated - My heads are part # C4AE-6090F - I believe a 427 high riser head? This is on a 428 CJ motor with what appears to be aluminum Eagle rods and a zero balanced crank. My theory is the previous owner spec'd out a full blown racing motor.........at great expense to low end grunt.

As for the miss/stutter I was chasing- well, I think I was simply looking in the wrong area - a case of a virgin driver learning the car - as I re-read my own comments in the post, I think I see this now...fine tuning simply wasn't going to solve this one...

Comments? Am I now on the right track?

What kind of value do these heads with the matching high riser manifold have? Are they worthless or priceless, or somewhere in between? Can I swap 'em out for a regular set of heads?
