usually you like to have a turbo cam be either split even, or favoring the exhaust a couple points.

I was thinking the same thing

Mine is a reverse split, speced by Virginia Speed. Looks like a good cam for a 408+ ci engine. I think it is too big for a 5.3L.

what about a nice 370

That would be a better choice for it, maybe the smallest ci I would put it in. Mine is in the 230 range with a reverse split.

Shawn @ VA Speed

that would depend on the application.

Shawn @ VA Speed

that cam is way to big for that application-you need something in the 22x range.

Listen to Shawn, he knows his sheat.

I would go with a 224/230 and something in the .570-.590 lift on a combo like that. Like a 112 LSA.

You need to call shawn and get one of his reverse splits. He spec's the cams for all of our big motors(Veee8, Fireball, myself, and a bunch of other guys).

Having tried a cam like that in an older motor, you may be surprised at the gains that can be had on your combo if thats the type of cam your running.

Would you ever recommend a cam that favors intake on an FI application? Im not trying to challenge you or anything either, Im just curious.

The numbers I provided are based on stock 317 heads and a biggish exhaust housing on the turbo for the cubes. My cam has no split but my heads flow alot better exh, I have more cubes and pretty much the same size exh housing. I have been thinking about trying a reverse split for mine as I think I am seeing high back pressure. Then I think that maybe I'll just buy another PT88. JK.Right know, I'm just waiting to get my AEM computer and maybe some bigger injectors to try my hand at some E85. Less heat should mean less pressure, right?

Phil99vette

If its a biggish exhaust housing, why spec a cam that will loose cranking compression and be hard to spool?

ya i think its alittle big myself and as for the rev slip usually with less flowing exhaust when you get to bigger flowing less restrictive flowing exhaust you can do more of a dual pattern i had good sucess with lloyd elliot (nighttrain66@msn.com) and comp cams myself on a great cam cammotion seemed to set me up with a huge cam but messed up duration i would have been bleeding soo much boost out the exhaust so keep in mind email him the price is great fast and tech support unbelievable he helped me for weeks everyday i had questions and so on for free before i purchased

Would this cam make no power on a 5.3

98Z28CobraKiller

What I mentioned will still have plenty of cranking compression and overlap. The split toward the exhaust is to increase exh pressure vs the heavy flow bias to the intake side on the stock heads.

Would this cam make any power on a 5.3

i think its too big and would be out of your power band not worth it spend the money where you can efficiently make good power to redline
