Jason, thanks for the information. Since it's kind of on topic, mind answering a few questions?

I've got a stock LM4 in my 944 right now. Outside of long tube headers and LS1 intake/fuel rail/injectors, the engine is bone stock. With tuning, I am looking at around 290-300rwhp. I have a 224/224 .581/.581 LSA114 waiting to be installed. Do you think 400bhp is possible with such a swap? Is this an ideal cam, or do you think I can go a bit more aggressive? Also, I was thinking of pulling the 862 heads and milling them down and doing a light port and polish. Think I could get close to 11:1 CR? How much would I have to mill to achieve such CR? Thanks!

 

[QUOTE=Jason Haines @ LPE;17372667]The 2002-2004 LS6 camshaft has even more lift and really should be used with lighter valves, at least if you plan to go to higher RPM (past roughly 5600-6000 rpm).

Interestingly, the article did say that out of all the factory cams, they got into valve float problems with the ls2 cam. It wouldnt pull cleanly to 6500, so the pull was limited to 6200. I dont remember if this was with the stock 5.3 springs or not though.

 

69-chvl i looked for the car craft on my local walmart shelves and they did not have it .

could you kindly break down the boltons the engine head? ie intake headers, what front accessories etc.

thanks

 

It had the ugly truck intake. Headers. Beehive springs for all tests, but they didn't say which ones. Stock retainers.
Stock!

They also showed some Crane rockers that looked more like YT, didn't look like anything in the Crane catalog.

thanks for the info. where they using electric water pump? alternator?

also, did they mention how much timing was being used?

 

None of that was mentioned. I don't imagine they had a water pump or alt, it was on an engine dyno. Also, EFI was by Holley.

 

thanks for the info.

 

So...... How is this related to forced induction?

 

B/c FI people use these cams - its not that complicated really
