t2 here in my dd, but its a m6 with 4.30's..............i say its do-able

 

Pred, When computing for DCR on the torquer, what IVC numbers are you using? I have been using the IVC at .006 number on the cam card, which is 71* on my cam with 2 degrees advance. Should I be going off the .050 IVC number and adding 15 before computing?

Also, I have the T2 cam in my daily driver, but I drive mostly highway, and i have heads. The added compression makes the t2 drive better than my f-13 was with stock heads. I probably wouldnt have gone so big on the cam if I drove mostly city miles. Since Im 80% highway, i think its perfect. It does take a little extra car driving in traffic though.

 

how do you suggest i do that

 

Heads. Even if you dont port them, youd have to pull them to mill and use a thinner gasket.

 

how much? im already at 10.9SCR

 

Im sorry, I got you confused with the original poster who i believe said they were using stock heads. Predator-Z will be more informed about the 6.0 (not that its the limit of his more-informatationalnessositude).

 

There is a spreadsheet that calculates (got it of J-Rod) saves time.

You need the advertised duration numbers at .006 which are 281 and 283 respectively.

 

see this might be a problem with your pistons,

For some reason I got you at 10.97>11.01 SCR depending on your piston deck height (but no accounting for gasket bore area.)

To optimise further 11.5 SCR and 8.56 DCR with 61 cc
and 11.67 SCR with 8.67 DCR with 60 cc

Keep in mind those figures are a close ballpark not exactly accurate due to the variation in parameters. So it is always good to take the least figure to avoid going over.

 

so you think ill have P/V issues right now?

 

Not right now, but if you mill or reduce gaskets (the trick is how much can you go without PTV issue)
Are you stock valved? (I mean your motor LOL)

 

yea stock 317 valves carried over to the 243 castings

 

This is what I would do:

I would measure PTV with a dial and get true values.
Then using a thinner gasket, I would raise the SCR/DCR as much possible without causing any PTV issues.
By doing this you're killing 3 birds (SCR/DCR and Quench)
Makes sense?

 

yep, only issue i have a set of new gaskets in my pile of parts.

 

Just for info, my TR224/114 pulled 431hp/410TQ last weekend with my 5.3 stg.2 Absolute Speed Heads.
