Yes but it will take race gas at a certain point.

 

what would need to be done to the 317s to raise the CR just a simple mill?

What would it take for the 4.8 heads to work? and why would you choose these over the 317s?

What do you think a safe CR would be if i plan on spraying at least 150?

And no meth or race gas.

 

I also very intrested in your reasoning for considering the 4,8 heads

 

you can run 11.1 cr and spray and not use race fuel. its been done safely. just dont get greedy and want to much of a shot.

 

well I think i came to a decision.

Im going to just use the 317s as is. My reason being is becuase i am on a budget to use the 862s would bump my CR to a point where i wouldnt feel comfortable using spray and the cost of porting them is just that another cost. if i milled dwne the 317s sure i could raise the CR a little and spray it but im not sure how much of the gas i want to use and even though milling would be not much $$ it still would be more.

So with the stock 317s i could spray and still be realativly safe.

Also i figured im going from a cammed 4.8 to a cammed,sprayed,6.0 and my goal of 12s should be attainable and plus with stock 317s i can just spray more if i wanted.

 

Hey Josh,

Good choice staying with the 317s, your truck should move very well with the LQ9.

Take care!

 

Whats up Goerge,


To be honest i was happy with the 4.8 but the crank bearing decided to start squeeling like a pig. We didnt even get a chance to spray it. (not sure if you seen the N2O setup).

So since the 4.8 doesnt want to play anymore I found me an LQ9 when all is said and done i should have a good moving truck (shooting for 12s) with the 212/218 cam and all the other boltons it should make some nice numbers.

 

I'm really interested to see how the 212/218 does in the LQ9. I was considering that cam myself.

 

The truck will be finished next week sometime. I will have some graphs to post up most likely next weekend.

Ive heard both sides saying its too small of a cam and others saying its going to make some good #s. I was willing to crak open my wallet for a new cam but i was kinda curious(sp) to see for myself.

 

I too am curious. Did you have the heads milled at all? I have an LQ4 and would like the idea of seeing what a set of milled LQ4s are good for.
