Getting motor this weekend.. (LONG)

[JMD Engineering]

questions after specs.

First - my motor consist's of the following:

RNHPerformance 347 block (stock block)
SCAT cast steel crank
SCAT forged 4340 steel I-beams
Probe SRS series dish pistons
FTI custom cam
SFI balancer
ARP everything/Professionally balanced

1.7 Scorpion rockers
Chromemoly pushrods
Trickflow trackheat heads/intake
Accufab 70mm TB
Pro-M 75mm MAF
Walbro 255lph pump
Adjust FP regu
30# inj.

MSD blaster coil
MSD Digital 6 box
MSD 9mm wires

FRPP shorties
O/R BBK xpipe
Slowmasters
3.73's

Ok - now my questions. with a good tune, what should I be putting down? would I be able to shoot 50/75 shot or nitrous safetly.. or am I pushed the limits of the block? any info would be awesome, as I am getting everything put together this weekend

a solid 347 setup should be close to 360 370 as a low guesstimate, stock blocks don't die until closer to 450 or 500,

all those internals in a stock block is such a waste of time. Even stroking a stock block is a waste of time. Your limiting factor is going to be RPM's, RPM's are a stock blocks worst enemy.

Thats a nice streetable set-up,I would say about 320-340hp or so at the wheels.

Actually for a stock block these internals will be great, yes they will hold more then a stock block but they are far from a waste. I would use forged internals when you step up to a DART block.

Jeremy, N2O will be no problem on the set-up, the cam specs are really nice a little different then what I have used in the past. See you Sunday I designed this set-up to be a nice powerful street car, that will make plenty of usable power
