Well...........I have a new project. A buddy of mine brought his car to me a few weeks ago, after hearing a loud bang from the engine. After pulling the 383 out, tearing it down, I found #3 rod had broken. Amazingly, the block hadn’t sustained any major damage. Besides the #3 intake valve slightly bent, no damage to the AFR 195s. Currently the block, heads and internals are at my machinist being prepped for a rebuild.

Current setup
95Z28
2 bolt block
Scat 9000 3.75
Scat 6” rods
Icon forged .040 over
Comp Cams XFI280
AFR 195 1039 (tel:195 1039) heads comp ported
Edelbrock LT4 red intake manifold
58mm TB
24x Torqhead swap
Pacesetter LTs 3” magnaflow exhaust
T56 3.73 out back

Last Dyno put down 414rwhp 397rwtq

After building the bottom end a little stronger, I’ll be making slight mods to up the power. I’ll keep you guys updated.

Finished some clean up porting on the Edelbrock manifold
Casting isn’t that great from the factory....in my opinion

Looking good! Planning on doing any other porting work? Head work?
I'm excited about these future mod plans.

All parts are back from the machine shop ready for assembly
Budget is tight so won’t be making dramatic upgrades

Any idea what caused the rod to break? Material failure?

Nice looking engine BTW.

Combination of things

-cheap rods not rated for the amount of power output
-uneven cylinder boring from previous machinist
-Detonation cuz small cam=high dynamic compression combined with aggressive timing running crap Cali 91 octane
-also the exhaust was built really bad...the Y necks down to 2 1/2” engine struggling to breath

Sounds fantastic! What ignition system are u running in it, and is that what was on it previously when it broke?
