Default 59cc chamber head.. would you still boost?

this is just for general knowledge...


my tfs 215 heads are milled from 64cc to 59cc. 346 ls6
I plan to do bottom end later on and could go with low compression pistons...
would you guys boost a 59cc size head? is it stupid? should I just pull the heads off and sell and do 64cc? how much of a loss we talking here..

thanks

I run 60cc heads on my 366 motor and have boosted pretty hard...

Those heads will give you about a 11.2:1 compression ratio which is far from ideal, but you can run some boost. 4 to 5 without methanol or 6 to 7 with.

yea def not stock pistons!
I would build bottom end and get low comp pistons and everything else.


just wondering if 59cc head is to small where I would loose efficiency of the motor and gains..

The only issue would be is that they would have a thinner deck because of the milling and might led to the heads lifting more if you push a fair amount of boost.

just to put into perspective, I run a -22cc piston with my 60cc heads.

since your FLYING!! you want to give me some help..
will my heads lift if I push past 14-16lbs?

besides pistons.. I would get -22cc or whatever was needed to get compresion to where I want it.
what kind of compression are you running?

I'm right around 9:1

heads lifting is all subjective, seems every combo is different... I run the ETP heads that have some of the thickest decks available on the market. I also run off the shelf ARP headstuds (not the L19 ones) and GM 5-layer gaskets

I have pushed 24 psi with no water pushing with over 20* of timing of course this was on C16 fuel and with a pretty sizable hydraulic camshaft (240+ intake duration).

For most combos, I think 20psi is a good upper bound before things start lifting if you are using good fuel and aftermarket heads...

sounds good to me. I am going to ask trickflow on how they feel.
I will def do ARP head studs when I do the bottom end, everything.

my cam is almost 240 on the intake but its a 238/244
I think it will be fine for boost lol.. n/a it made huge power.

My car has 59cc heads on it right now with stock bottom end and I am planning on running 6 psi for a little while. I am tuning it on E85 so I'm not to worried but there is no way I would feel comfortable with that high of compression on 93 octane! When I build the motor I will use a -25 Wiseco to drop it on down. I am around a LOT of BIG HP imports all with turbos at my brothers shop and from what he is telling me the smaller chamber heads with a big dish piston always make a little more than the other route! I guess Fireball proves this is a great combo on LSX platforms as well!

I've read your build up thread but can you go into more detail on the specs of the motor?

I'm assuming your using a 6 bolt block or some type?

rods?

crank?

thanks...

I had TFS 215's milled to 59cc in my 10.8/10.9 NA Camaro. I'd say you should look into what your eventual combo would be and see if you should run pistons with more dish or look at getting into a different set of heads. I was making about 500 crank with those heads and a stock cube 11:1 setup.

yea thats just about what I am making..

I was just pondering the idea of boost with these heads for general knowledge.

I have to decide if I want to keep the high compression, build the bottom and keep my nitrous. Pretty nice setup.. OR build bottom end with low comp pistons and go boost. (alot more money but more power all the time is nice )

also dont forget to factor in everything else. like stroke and bore...thats going to effect the compression as well.

Coming back to my earlier post in this thread I will update that I just got my turbo (tc76) camaro tuned with 59cc heads and stock bottom end on just under 7 psi it made 590 on a mustang dyno!
