Well, he already has his block and heads, and if I was that far into a build I wouldn't care what anyone said I would at least get it put together and see how far it could be pushed and run.
I love seeing people doing it their way and getting it done right, and having a solid combo hold together for a couple good seasons of racing. I do look foward to seeing how fast they can get this thing to go.
I just hope it doesn't end shortly because of instability in the bottom end.
Godspeed guys.

Just for the record, when Kurt Urban built the 352" LS motor that eventually went on to set the record he had way more than pinned mains in the 352" iron block. He used a Billet main support system that mechanically locked the mains in place with the block. Bottom line is its your build and you will do what you feel is best for your engine program. The recommendations are not coming from those with no data to backup their claim. Best of luck with your build.

Maybe I am confused but the motor in casper made 1600hp or so and the OP said the goal was 1500+hp. The car went 6.88 @ 200 in a lightweight top street/pro stock style car. The et comparison is apples and oranges due to the difference in chassis and tire selection. How many people have built a stock style iron block(no pinned mains or cement) and made 1500hp+ with zero relibility issues? Or is 1500hp+ not really the goal?

1900hp according to what i've been told, with twin 80mm, they were able to get more rpm with smaller turbos.
Originally had twin 88mm wouldn't go above 7500rpm, made 1600hp.
by calculator I often use, i'm seeing 1911.8 hp
(2700lbs, 205mph)
I know a iron LS 402 in Australia, dynoed 1380rwhp, Iron block, dart heads, 106mm turbo 35psi. I recall him mentioning bending a set of steel rods.

Casper was 2900# and ran 6.86@205
Main caps were steel, pinned and had custom girdle tying in the lower case at oil pan rail.
Engine made 1697hp@7500 with 88mm turbo's, but they surged at 7500rpm 30psi.
80mm turbo's allowed 9100rpm at 32psi, we figured it was over 1900hp but never ran that configuration on the dyno.
Lightweight Oliver rods were used (literally used), and weighed 610 grams.
3.5 Callies Magnum XL without CCW.
All bearings looked great when I took it apart, main caps showed minor movement.

This isn't lookin' like much of a build thread here anymore! Lets let the man get back on track and start a topic elsewhere to debate about at what point you should consider pinning the mains. It's great info and deserves a thread as much as this guy does his own build thread.
Good luck to you OP and can't wait to see the finished product!!!
