I finally finished my 588 (4.500X4.625) with the PSO Heads. It has a Custom 55mm camshaft 285/300 at .050 with .954 lift and 15 to 1 compression. I used an old Mega block I have had for a while. I used the new Quick Fuel QFX 1050 carbs. John Marcella built the tunnel ram manifold. The Heads are the first ones I did a long time ago and are a little different than the improved ones we have now. I used a Peterson 5 stage dry oiling system with a Charlie’s pan. The oil pressure was too high for the RPM of the engine and we started moving the cam with positive results. The first pull from 6-7 thousand RPM it made 1099 HP. The Dyno starter failed and ended our day early; it was still making more power on every pull. I know there’s still 20HP there.

Pick up 20 and you'll be right around 1200. Awesome power for a straight head. I wonder what it would do with one of your new castings in a full max N/A effort??? Are you going to fix the dyno and run it again up to 8500 or so??? And is the A/F lean or is it just me???

You wouldnt call this a max effort N/A effort?
Good numbers, nice going Pete..

I've seen engines with 17+ compression, well over an inch lift and ring stacks from hell, insanely light cranks and bob weights, among other "tricks". I don't know whats in this engine other than whats listed and whats listed in not on kill. Plus he said the newer PSO head is a better deal....so no, I wouldn't call this max effort.
Killer, but not an "on the edge" deal.
Would youc call it a max build???

I would say its a good effort. I would imagine the engine has a good nice ring pack, and the parts are pretty light, titanium valves, aluminum rods etc, sheet metal custom intake...
I would say yes..pretty good effort imo.
Sure diff heads, diff cam, diff pistons might more power..but it would be the same engine then either. 
Sure it would be easy to spend another $10-$15K on the same engine..for what 5-10% increase in power maybe?

I agree...
Its just that I have a chevy/ford complex. 
Those cats don't start talking about a serious effort until every last part is messaged to within an inch of its life and nothing goes in unless its state of the art and on the edge of destruction.
This engine makes real steam in a reasonable RPM range and should be fairly reliable. A nice overall package and mighty fine looking.

that manifold was built really by et performance when john worked there wasnt it? i remember talking to pete about it and how much work it was,, a buddy of mine worked at et and told me they had well over 60 hours in it,, had 40 hours in machining the runners,, you might not beable to see it from the pics but each "pair" of runners is made out of billet,, ie, runners 1,1nd 3 are one piece transitioning and ovalish port opening into a round opening in the plenum. very nice work to say the least,, i doubt john would do that today since he has no cnc machine though cary could machine them up but id have to say that would be a 5k manifold,, im sure john would just use a folded runner like all his other stuff. nice job on the power pete,, generally you are limited to about 2.4hp per cfm of airflow with a motor like yours,, to make 1200 hp you would need 500cfm,, so you maxed out those heads im sure. 1200hp in that car 2300-2400lbs?? shouldnt that be a 7.20 or so? good job

A friend of mine recently bought a set, to see the work that he puts into the heads and intake in person, is to really appreciate.
