So I have been tossing around the idea of swapping to l92 top end because the 6.0 is not really cutting it power wise like I thought it would. My biggest question is how will my current cam work with them and what is the best intake to run with them? Also they will more then likely be milled a little to bump up cr since from what I have gathered they like cr and smaller cams for the most part.

 

The heads will like that cam. Run it

if you dont feel like following the link the jist is- L92 truck intake, LS3 car intake, or a Vic Jr.

Actually, I'm pretty sure that FAST makes a 102mm rect port maifold now as well.
F.A.S.T. LSXR™ 102mm Intake Manifolds from Thunder Racing
Yes. They do.

Idk if there's a reason the 102 FAST is left out of manifold threads I've read (other than the stupid expensive price tag).

I do believe that the L92 truck intake will probably be your best bet. cheaper than aftermarket and If i remember correctly it was more efficient where it matter than the LS3 intake. (I think the L92 and LS3 shined down lower and up top, respectively) Then again I could be totally wrong.
Hope that helps

 

I would like to find an l92 ported intake but the stopped porting them from what I was told. Any one know how the vic jr does with these heads as far as rpm?

 

I run a Vic Jr with a FAST 4150 throttle body and I wouldnt run it any other way. What do you want to know about RPM? I can tow a 23' deck boat up hills with out downshifting into overdrive.. Turns 7200 rpm... Plus if you ever go the nitrous route you can get alot better 4150 nitrous plates to run...

 

And I heard your Vic Jr is awesome looking too!

 

Pics? Lol

 

Dirt track is your intake ported and how much of a stall are you running? As far as that throttle body I would love to run one but dbw is killing my choices.

 

I had a similar cam as your comps cam lsr219/227 .607/.614 on lsa 113 I had my l92 milled a total 45ths. I had ly6 6.0 all I can say it was a killer setup with my 3000 circle d tq you will have alot of fun with that go for it

 

I have ls3 intake if your looking for one but for the most bang for buck will be a truck intake
