I DO have 15 cubic inches on you (555 cid) but I think about a full point less compression (I'm at 8.6:1)
I believe we have the same heads.... AFR 325 cnc..
My cam is a bit smaller .644 in .629 ex. Lift. Duration 239 in 246 ex @ .050 as it's spec'd for a blower
and we made about the same power N/A.... I dyno'd mine wet with Eddie Marine exhaust...


Maybe it's because I essentially built my engine in my living room, and as ya'll say, the cam was designed at a kitchen table.. LOL


P.S. Congrats to the O/P on an awesome build :party-smiley-020:

Not all Butt Hurt bobby thou, Jones came up with some tiny cam for me too. It would have worked great in a ski boat I`m sure, I`ll stick with my 651.





Trash day is wednesday if anyone is driving by...:daz:

How many hours have you logged on it since the dyno?

. Every detail was logged... Plain and simple he didn't do a good job on my builds...

Not saying you're hiding anything.. OR that it's necessarily your fault..
Was just thinking possibly something mechanical going on could be causing it to not pull on the top end...

Maybe his aim was just better when he spec'd mine.. (wait, wrong cam guy :) )

Typical 540, afr 325 heads , almost same cam he specs within a couple degrees on most similar builds

So, where are the other 700hp 540 packages he has done? It be nice to see what you are missing.

I agree also on the exhuast. It's still a cruiser, so lots of idle time
