Buy what YOU like. Crankwalk is slightly overated. DSMTuners did a
POLL and it was surprising how low the CW numbers really were. Each car has it's advantages/disadvantages. There are parts on the 1g which are better (intake manifold, throttle body, head, rods, etc.) and there are parts on the 2g which are better (pistons, MAF, exhaust manifold, O2 housing, etc.)
You can make over 400hp reliably if tuned correctly, I made 390-400whp on mine and it stayed together (until I took it apart
). That would calculate out to about 460hp at the crank on a stock short block. My 7-bolt didn't crankwalk either (only had 59k when I pulled it, but the crank is still well within spec) and I had a CM 2500lb pressure plate on it.
As far as the oil squirter being a problem if they clogged up, it's actually the other way around. A clogged oil squirter would raise the oil pressure at the main bearing. A squirter that is stuck open would lower the oil pressure at the main bearing. Even so, no one has proven it's the cause. The 4g63 oil system is very good, so I doubt an open squirter could flow enough to kill the oil pressure.
