here is my cam for my 5.7

MTI X-1 230/227 .591 / .571 / 112

so what do you guys think? i got a good deal on it so i figured i would try it out also will stock length pushrods work with this?

That isn't going to be a very friendly forced induction cam. You might need a longer pushrod if your heads aren't milled any. It really depends on the on how much smaller the base circle of the cam is. It is going to be smaller than stock in order to get that much lift.

 

<img border="0" alt="[bang head]" title="" src="graemlins/gr_banghead.gif" /> I think that is going to "leak" boost. The valve overlap (the 112 lsa) is too much for FI. Something on a 114-116 is a good lsa for forced induction I have heard. With the 112, the intake and exhaust valves will be open too long at the same time. The time that both the valves is open is know as "scavenging". The scavenging effect is good for NA cars because having the exhaust valve open while the intake valve is open creates a suction from the exiting exhaust to pull in more intake air. But since you have boost the more valve overlap you have, the more boost will escape. i.e. you don't need scavenging if the intake air is being forced into the cylinder instead of being sucked into the cylinder.
The reverse split cam is not the best for FI either. Gas expands after combustion, and FI creates alot more axhaust than NA. I know there has been great discussion about reverse split cams in the Internal Engine section. You might check that out to understand more than what I would be able to say about it.

 

i intend on getting a custom grind for my forced induction motor so thats why i got this big one i wasn't really worried about it for turbos since that will be awhile anyways but will this cam like nitrous? i thought about that and it might be something to get me a little extra power until i get my turbos and everything
