high compression 3400 build

[cammed3x00]

so,for those who dont know this isnt my first rodeo. my mods list includes:
old 1393(stage 2) cam
3500 heads
comp 986's
ls lifter springs
s&s
cai
65mm tb
2.5 custom header back
comp ported manifolds
tune
28 lb injectors
tce afpr

to add to the madness ive ordered:
dohc pistons
head studs
stock conrods
cometic 3400 head gaskets, compressed thickness of .075 to yield 11.6:1. more parts are to be ordered.
probably p series rod bearing
pre 00 timing set.
new crank cuz the snout on mine is stripped
maybe arp rod bolts
maybe arp main studs

i need advice on the last two.

I'm not bothering with main studs.....my static compression won't be as high as yours, but I've got a decently larger cam. Even still, I think main studs are overkill unless spinning to 8K RPM or above.
The rod bolts are worthwhile though.

[cammed3x00]

ben said the same thing. its really cheap insurance. and the powerband of the cam peaks at 6500 and i dont even rev that high so i think ill pass on the main studs

good luck with the build, cant wait to see it.

double roller set?

On his old 1393 grind? Not necessary, although cryo-treating the 94-99 timing set would be worthwhile.
I will be using (and have) the TCE DR timing set.

yea no go on the dr set but funny you mention cryo treating the pre 00 chain, i was actually thinking about that. dont know how much that would cost

I've used http://www.300below.com/ before. Their prices for doing brake rotors was reasonable and turn-around was quick. You can probably find a more local place if you look around.

thanks matt. on a side note, i may be moving back up there soon.

some parts came in

What is the advantage to using DOHC pistons over Diamond Forged SOHC version?

[cammed3x00]

price really. im not increasing combustion chamber pressures enough to worry about popping a piston so the extra strength isnt needed. and with a specific combo of parts, desired compression can be achieved. i got these for 130 shipped with wrist pins.

What CR are you looking at? How are you going to get there? DOHC pistion will work in a SOHC 3400 V6?

Ken, old buddy.......the 3400 is an OHV (overhead valve) motor, not a SOHC (single over-head cam) motor.
And he's looking ~11.6:1 with the DOHC pistons, 3500 heads and .075" head gaskets.

I never knew the 3.4 dohc pistons were the same diameter as the 3400s I am intrigued. I wonder how tight the quench will be with those pistons and hg. Also any serious head work/bowl work?

Also I would reccomend deburring those valve reliefs it can help prevent predet.

Yeah I knew that. I was just blinded by the excitment of another option for an engine build.
And of course

Double posting now lol you are excited!
