First of all, I'd like to thank all those that read this post. I know there are many members who seem to ask the same question. I appreciate those that take the time out of their schedule to answer some of these questions.

I purchased a mustang in boxes. I bought a used 5.0ho as a temporary motor. I should have the car rolling by Christmas. After christmas I would like to start a performance build with the parts that came with the car. I understand that certain combinations seem to work well together as a system. I bought a book to try and answer most of these questions on my own. However, the answers I am looking for seem only available to those with experiance.

The project motor was assembled and running. It was dissassembled and left apart too long. There was rust on the rings and in the cylinders.

What I have:
302 roller block that will more than likely need boring
Holley heads, 2.02 intakes, 57 cc chambers- that have been ported- I had these rebuilt by a reputable speed shop in Phoenix AZ. Their comment was it was excellent port work with material removed in only the right places.
Isky 265/275 cam- here is a link

INTAKE TIMING DURATION: 265 deg.
OPEN: 20.5 BEFORE TDC
CLOSE: 64.5 AFTER BDC
CAM LIFT: .313"
VALVE LIFT: .50"
VALVE LASH: . HOT
. COLD
EXHAUST TIMING DURATION: 275 deg.
OPEN: 69.5 BEFORE BDC
CLOSE: 25.5 AFTER TDC
CAM LIFT: .325"
VALVE LIFT: .520"
VALVE LASH: . HOT
. COLD


LOBE CENTER: 112 deg. OVERLAP: 46 deg. CAM ADVANCE: 0 deg.
THE ABOVE TIMING IS CHECKED AT .020 (OPEN) LIFTER RISE
.020 (CLOSE)

The following timing is taken at .050" lifter rise and gives a more accurate determination of camshaft position.
INTAKE DURATION: 218 deg.
OPEN: -3 BEFORE TDC
CLOSE: 41 AFTER BDC
EXHAUST DURATION: 228 deg.
OPEN: 46 BEFORE BDC
CLOSE: 2 AFTER TDC

I have the stock rods with ARP bolts.
Stock forged pistons with some vertical lines but not much.
A windage tray
1.7 ratio trick flow rocker arms
comp cams connecting rods
Edelbrock RPM Air Gap intake
Holley mechanical secondary 650?? Not sure of size, the air horn was machined off
50 ounce balancer

I am prepared to rebuild the bottom end. I am not necessarily interested in a stroker unless this combination deserves it. This car is not a daily driver. When I drive it, it will be driven like I borrowed it from my brother in law. I may even take it to the curvy track. I am not necessarily a drag guy. Sacrificing low and mid to get an extra XXhp isn't my cup of tea. The car has a 5 speed and 3.89 gears. It's a 66 coupe. If I had to set a goal I would say 400hp at the crank.

I am looking for advice on compression ratio and a displacement recommendation.

Do I need to place roller lifters back in the same bore? I did not label them. If so, can I buy new roller lifters for a used cam?
Some more technical questions if you don't mind. On the powerblock tv program, one of the shows installed a copper line in the lifter valley to get more oil pressure to the rear main cap. Why doesn't my 'build a stroker small block ford' show mods like this? I read another article where Marvin of MCE installed the pistons backwards on a build for one of the magazines. I can't find it but the books I have read made no mention of the mod either.

Is there a book that is more than the basic how to assemble a performance engine?

Thanks for your help. I return the favor to others when I can.
