My 400 block is bored +.020 and will use stock crank and rods for a final of a 6.6L 405.

Do not use the stock rods for a 400 sb.

Too late. I had them rebuilt and awaiting new pistons and no more budget room for new rods. The engine won't ever see screaming high RPMs.

Good analogy, for enough money they can be made to do whatever you want.

That's unfortunate. The stock 400 rods are limited in strenght-even less that the stock 5.7 rod. The rods were never designed for over 4,500 rpm. They are too short to make any good torque over 4,500 rpm.

Yeah I found out all about that after I had the work done. The only thing left is I'm waiting for the pistons. Had I not already had ARP studs installed and everything rebuilt I would consider upgrading the rods.

Scat Rods $285.OO. 7/16 cap screw bolts---good to 700 hp. Pretty damn things, too pretty to put in an engine. Got them in my 400 -- I used the 6".

One of the things about this rod is it is for stroker engines-- will clear cam with no work--perfect fit.

Don't think that motor will make too much power for the stock rods. If you stay away from boost and nitrous it should be fine. I wouldn't run anything but forged parts in any performance motor because I'm paranoid, but realistically I don't think you'll run into problems.

Glenn, H or I? I have the Forged Scat 6" H rods in my humble lil mouse.

I've got the "I" Rods. This 400 is a test motor for rod lenght and Hyper pistons. Just a cheap 475 hp+ motor ( according to the computer it is 536 hp ). The next motor is going to be the "trick" setup. Funny thing is; I've got this 454 short block sitting in my shop--thinking 496.

BTW all SBC and BBC stock rods are forged.

I have an Eagle cast crank with 2 bolt mains in the 454 in the Chevelle and it has 2 years of racing on the engine without any issues.

200cc Vortec heads and a 230/238 cam will need at least a 100shot of juice to reach 536 flywheel hp, sorry. BTW, desktop dyno said that my motor NA should have been in the 600s, it was actually in the low 400s after tuning... NA. Desktop dyno is a tricky bitch to get accurate numbers from, I even input the head flow data across the lift points.
