3400 build Plans Finally Complete

[sprucegagt]

you would end up with a 11.56.1CR using the camaro pistons and the 3500 heads

I thought it was the DOHC pistons w/ 3500 heads that got you 11.5:1.

[Superdave]

What can i do just using stock pistons and acheive very close to 10:1?

Have .020" shaved off the tops of the pistons and run the thinner .040" RWD gaskets...

[19Cutlass94]

you could mill the heads.

[SappySE107]

Camaro pistons or 3.4 DOHC pistons. I don't know what the camaro will give you exactly but its less than the DOHC.

[Badassoldspower]

How can I acheive a higher than 10:1 ratio on my 3400 with 3500 upper end?

[SappySE107]

I had over .200" clearance with the 1331 grind. I would guess there will be enough room but I can't say for sure.

Drop right in

Nice I think im getting rid of my forged stock copies then. Sorry to whore up and steal the thread here, but will there be any clearance issues with my cam (1615)

John, it sounds like we are building a pretty similar engine, minus the cam and top end (unless you are going 3500) Good luck with it either way.

Ben, do the 3.4 DOHC pistons have the correct wrist pin size for a 3400 rod?

[SappySE107]

Colin dynoed 222whp. The 3400 is Eric's and I have no video yet. Im dying to see it as well.

3.4 DOHC pistons (not forged). 3500 heads, ported, with ported manifolds and 65mm tb. Lots of other things were done to the engine, including a full balance job. Its running on pump gas (premium). He is running the stage 4 cam. Low end isn't where he wanted it but he is using the stock 4T45-E and 3.05 (or something around that) FDR and stock torque converter. Compared to the power increase after 3000 though, im sure the bottom end isn't all there. With a transmission upgrade, that won't be any problem at all

[3400-95-Modified]

Why would you buy MMS stuff when Ben has so many more cam options that can put out well over 220 crank hp.... or please tell me you mean 220 whp...

I did 13.8's with 206hp 238tq IIRC.... I'd have to look at my dyno sheets again

[john_V63400]

Oh yeah does any one know the cyl. tolerance as to how much compression it will hold up too

[john_V63400]

Wow really, do you have video?

Was the cam stock?
How about the heads?
What pistons did you run?
Were they flat top,dome, or dished to achive that compression
And how was daily drivability on 91 pump gas, because I want that compression but afraid I wont be able to drive on 91
