Choosing a cam

[TYTILIDIE]

I have some things are going to be going on the trudck this summer and I know for sure Ill be needing a different cam.My question is, can I find some type of cam that will be good with my 20g and ok to upgrade to a much larger turbo in the future without having to swap cams again?

Re: Choosing a cam

Are you looking off the shelf or custom grind?

A really good cam is spec'd to the combo you have. There's some wiggle room, but you're probably better off taking an educated guess as to the turbo, heads, etc. that you plan on working towards. This won't be ideal for your 20g, but it won't hurt it, either.

Re: Choosing a cam

Well, I was thinking custom grind but the more I think about it, the more I feel like a custom would have to work perfect with everything and if I upgrade then I think I would lose the whole point of hte grind in the first place. What off the shelf would be good to run with :
PT60
3" DP
Meth
Vortecs(2.02, port and polished, crane gold 1.6's)
Stock W motor, 9.5:1 comp?
Cant think of anything else that would affect the cam chosen.
I have thought about doing all this and putting it all on the stock motor first then taking a year and building the bottom end and next year, in the spring, pull the motor and freshen the top end up and swap it all to the W motor. This would give me more to play with now and give me time to build a nice bottom end.

9.5 comp ratio sounds high, wouldnt staying 9:1 or lower be better. just my thought

Re: Choosing a cam

i like my 422 with the 9.5-1 compression, with a 63 turbo

Is a W motor a balance shaft block? Balance Shaft cams are differnt than Non BS cams.

For off the shelf I would go for a 415 (maybe a 412). Campbell Automotive's custom cam is a reversed lobe 415, Turbotime sell a 214 cam has equal lobes with a more agressive lift and a little more duration than a 415. I think both of the above custom cams have a little more lobe seperation than the 412/415 (which have 112).
