The only thing that works with cathedral is cathedral, same for rectangle port. Its the entire top end, not both.

 

The more I read I keep thinking about just having my 317's Cnc'd since they are close to the 243's am I crazy to think that a set of Cnc 317's/ls3 intake and injectors can get me in the 425 range? If they can I might just stick with that setup as the cost is minimal and it will keep my CR low for an eventual turbo setup down the road. After all this motor is in a 2600lb car

 

I think you could do it, call AI and a few others, see what they say

 

Just realized i cant run ls3 intake with 317's.. so the question is this. Spend the money on porting my free 317's and dropping 850 on a fast + some upgraded injectors for the ls1 fuel rail or I could also buy some 243's already done 15-1800 maybe more + ls3 intake and fuel sysyem.. im leaning towards the 317's what do you guys think?

 

Youve still got the ls3 **** backwards.

If its ls1/2/6 you cant use any of the ls3 stuff, except maybe the injectors and fuel rail

 

317/241/853/243/799 = LS1/2/6. The ls3 manifold cant be used with any of those

 

If you read my last post i clearly stated that I am aware of what works

 

Didnt seem like you did going by that

 

what electronics setup are you planning on using after the intake swap? the lq4 has a really nasty looking harness.

 

I'm just going to keep it the way it is.. The motor is in a 77 280z so everything is kind of tucked anyways. I went ahead and ordered a fast 92mm intake, ev1-6 adapters and 03/04 cobra Injectors. Waiting on a call back from AI and mast for head options.

 

very nice, im gonna go ahead and hurt your feeling some with mast though. if you arent looknig to spend a minimum of $2500 on just heads, then be ready to gasp lol. they are fantastic heads, just wicked expensive.

 

Lol yeah I heard they where SUPER expensive.. If I could get AI to call me back I could get this ball rolling.. On a side note does anyone know if these 39lb injectors will even run in the car without a new tune? It would be nice to cruise around on them untill my heads are done and a final tune is to be had.

 

Yea I think you will be ok for the time being. I could be wrong, butI dont see it being a problem

 

tainted who did your heads?

I think im going to start calling other companies that actually post phone numbers on their sites.. I hate waiting 3 days for someone to call me back so i can spend money in their shop it just doesnt make sense to me.

 

They are texas speeds PRC heads. They are a full aftermarket casting, they are not a factory head.

 

They look amazing

 

Toying with the idea of turbo now..

 

Whatev... His heads look like what Im in the process of shitting out right now.

Sausage egg cheese and biscuit gravy topped with a 16oz redbull if you are curious. It is not pretty.

 

thats what you get for eating mcdonalds, its all a bunch of processed chicken dicks, cow anuses, and god knows what else

 

Hardees biatch!! I'm high class!

Right up my line of work.

Wait.. What....
