Just had broken rod not to mention a broken Block
now I'm building a new forged 347"
My question was in 347 on D1SC set up running 12 PSI on pump gas, also will my stock heads can handle that much boost?
will it go over 600 rwhp ?
Setup is:
forged 347 Compression will be 9.5
stock ported heads
226/228 .585/.588 on 113+3 LSA
Custom Fuel system
Stage III spec clutch and Fidenza flywheel
Stock rearend

here are some pics of my old engine



just look what happend to my rod

140+RWHP is a good estimate depending on supporting mods

that stock rearend isnt gonna hold up for long

12psi should get 600rwhp I have friend got 465rwhp with 3.9psi with STOCK Heads unported too.

I may suggest changing the cam too.



Depends on how he drives the car.

i think so.. Be sure to get a good blower can like the SC2 from speed inc or EPP also sells some good ones as well. I made over 600rwhp on 14psi on stock 6.0L heads with 9.5ish compression on my old 347ci combo..
