Nitrous 346 build up
Nitrous 346 build up ok guys, b4 we get into the "do a search" ill go ahead and clear the air by saying i have, i've found bits and pieces of what im looking to do, but nothing that is definitive to me..so im looking to my f-body brothers help..what im looking to do is build a street only nitrous 346, i've got the block already, and going to forge the internals, im raising the compression to 11:1 ..that much i have decided, now what im having trouble with deciding is Head and cam set up..looking at TFS or AFR not sure what size 205's or 215's, and as far as cam im thinking G5X-3 or the MS3, going to run a 200 shot, just looking for input on what your thoughts are, and why you would think so..thanks guys...and my apologies for making the thread kinda lengthy

Thanks brother, 225's huh? interesting, i thought the 205's or 215's would've been better, but im up for anything...do you remember the specs on that nitrous cam..and did you have to fly cut the pistons, and one other thing did you mill those afr's

specs are custom grind threw East Side Performance>>>>>>>
youd have to call talk to sean, tell him you want the same N2O cam Noyzee used in his 346. IT WORKS!!!
as for pistions, i used dimond, but i dont think youd have to fly cut.
and no, i did not mill the heads
thanks again bro, its def something im going to look into, and i might just have to give sean a call..just one more question for ya, and ill leave it be, i've been reading and hearing alot about the TFS heads, just wanted to see what your thoughts were on that..if you want to PM with your opinion thatd be cool..thanks again

Untouchable, sorry but, a "street" only 200shot nitrous car, and then 205cc heads and the MS3/G5X-3 cams just dont seem to flow together. Why? Well, the 205's are great heads for more of a lower rpm NA or mildly & not-so-often juiced build. 225's will be the flow for the bigger shots and better kills, of course your weight, cam, etc do play into it. Also, the cams, I would look for a custom nitrous grind over the ones you picked. Do they run good numbers for NA cars...yes, but not enough results out there for me to agree using one of them on a nitrous built "street" engine. e.g. I had an Ed Curtis ground 231/242 .637/.622 @ 114*LSA cam, ground to maximize 300 in the hole, and be street friendly, and it did just that, although I only took it to 210shot sizing. Idle was much smoother than either cam you mention which added to the "wanna race bitch!" attitude and many were very surprised to heat those spec's after witnessing it cruising the strip and daily driven to work.
Depending on how often you plan to hit the bottle, I would make sure the rings are gapped on the loose side to avoid scoring the cylinders whilst on the sauce.
My experience, the ETP heads have many advantages over the others, mainly the 11* valve angle, allowing larger cams, more duration without having to flycut. Also, of note, my buddy talked to a few builders and was told the TFS heads will be right up in the league of the AFR/ETP/Dart etc... If I were to go back to a fully built setup, I will be buying TFS or Dart heads and another EDC custom cam. GL

Brett Foote Cat3 you make an excellent point my friend, and i was thinking of those cams b/c of what i've seen done on N/A power..the bottle would be there, but i wouldnt be hitting it as much as it would seem..so basically im going for a beast on the motor, with having a little bit of insurance with the nitrous..and yes i will be running forged pistons...This setup that i was thinking about with the g5x3 and ms3 was a base, just to see where i should take it based on opinions from guys like yourselves, im a tubo man as you see in my sig, so im tryin to gain the knowledge and do it right the first time without the headache of loss of time and money..and from everything i've read and reading, and what you all are saying, im sure i can get into the realm of what i've got planned..thanks again guys, and feel free to keep the ideas coming
A little off topic, but who did you have sleeve your ls6 block? A buddy had some liner slippage problems from another site vendor, so was wondering as i may go this route. I want to keep the ls6 block and heads. any insight would be great.
