Pat G just speced my cam for me for my 408 as a 235/242 .638/.613 Just wondering how agressive this cam is and what would be a compared cam on an LS1 such as a Torquer v3, MS3, MS4 etc.

Its not very aggresive, it would be like ummm maybe a 228r? 228/228 .588/588 114lsa

Are you wondering about the sound of it, like the chop? Provide us the LSA of the came and we can figure the overlap. It will give you an idea of the "chop".

I have an MS4 in my 383 which is a 239/242 .649/.609 on a 111 or 112. It still really aggressive with the increased cubic inches. Circle D still speced out a 4000 RPM stall for it though.

sounds like a nice cam depending what you wanted it for,, whats the LSA,, id be happy with that cam

its a 112+3 LSA. found 2 youtube videos on it and it sound pretty lopey. just wondering what the power potential is on it....

and if it is equivelant of a 228R thats fine with me, i had that in my car before this build and loved it for my DD. and i didnt have to worry about changing out my valvesprings all the time

Even on a 408 thats still a big stick, not a donkey D, but still really healthy. It really depends on the lobes used, what your valve spring life is going to be like though. Those same lift and druation numbers on lobes with really agressive ramp rates could be killer, or with mild lazy lobes could last quite a while. The maximum acceleration and jerk rates of the valve is the key factor in determining valve spring life.

youre gonna be changing valve springs fairly often (about every 25-30k miles). Dont get me wrong, the cam is by no means small, but its not no TRex type deal.

I belive they are EHI intake lobes and LXL exhaust but ill have to double check

any other input?

14.5 degrees of overlap, should sound good. MS4 with an 112 LSA has 16.5 degrees of overlap for a comparison.

^^^ thats what i needed! thanks! how do you calculate the overlap.....

Blu99T/A

iTrader: (5)

(235+242)/4 (-112) *2 = 14.5

Let me know if you need anymore info.

This is correct.

Hope you're not using stock rockers...

Jimbo1367

why? lift or ramp rate?

thanks,

Lift.

Trunion upgrade will work fine correct?

Sales@Tick

iTrader: (3)

For sure! I always suggest the trunion upgrade if applicable to the combination.

What about the comp ultra golds.... i have a friend selling his and i can get them locally and for the same price as the trunion....

This cam is very simaler to the tsp tsunami. 235/240 .647/.608 111lsa. So it is not very aggressive for a 408
