Cam help too many options Hey guys need some help on cam selection ,iron 5.7 ls1
basic run down on engine
862 heads port and polished inlet valve upgraded to 1.95 heads being shaved to 58cc waiting on flow numbers as heads currently being worked on.
forged -6 pistons think we worked compression around the 12.5 to 1
Forged hbeam rods
ls7 lifters
Merllings hi volume oil pump
Electric water pump
Trailblazer ss intake 50cc injectors
Holley sniper 92mm Tb
long tube headers full 3inch exhaust
The car is 2500 lb
4l80 e transmission will put stall in to suit cam choice
3.7 gears 15 inch tyres 255/60/15 drag radials
Car is weekend fun car some strip time as well.
I have had so many recommendations so fairly confused I was looking at a 226/232/112 600/600
if anyone has anything else to make this a better combo please let me know cheers

1. This needs to go in internal engine. 2. For all the money you're spending, it would be ideal to find some 243/799 castings and work those. I bet you're giving up 20/20 and significant area under the curve. 243 heads are cheap now. https://www.ebay.com/sch/i.html?_fro...+pair&_sacat=0 Cam is fine, install, tune properly, send it. So many good off the shelf cams now, unless you're REALLY spending money on a high dollar build, custom cam probably isn't worth it. 3. What kind of car is this at 2500lbs?
Or you could just call Cammotion, tell them your specs, and order the cam they recommend. https://ls1tech.com/forums/generatio...arathon-2.html

That Titan King on an LS1 will need a Helluva high stall converter, for sure. Its not gonna be an easy cam to live with on the street. The only way I'd go that rad is if the car is more strip than street. Your 12.5:1 compression will help it some. I had a 238/242, .638"/.646" lift on a 114° LSA, but this was on an LS7, so not apples to apples. It drove fine, good tuner+80 more cubes will do that. But the cam your looking at is considerably more rad than mine was. But if a strip car, should be great. IDK about HPDEs, though. Youll give up a lot of low end to lower midrange power with the Titan. My .02.....

It's definitely a big cam and I believe to big for what I'm going for definitely like you said for an ls1 , the 226/232/112 is true tested cam with my tuner he constantly gets between 420 to 440 hp to the wheels with cam heads and exhaust ,I was hoping going little bigger cam with car being so light with decent stall but drivability is also something to consider As its not a full track car.

Usually for a street/strip I suggest Cam Motion Titan 4 227/232 113+4*
But with your 12.5 comp I would suggest Titan 5 232/238 113*+4* will need at least 3k stall.
With 3.7 gears and 2500 lbs minimum & 3k stall Titan 5 is the sweet spot imo.
Also agree on the get some 243s.

Thanks for the cam suggestions mate appreciate it ,because the 243 are the best flowing out of the cathedral ones I can source them at one point for sure,for now I will use the 862 which have had a fair amount of work done on Them.I honestly would look at some after market ones a little later once its finished also so you think the heads in the current build will be the limiting factor then? I do some people's say just because the 243 flow better some say the 862 actually make more power ?

From what you've told us, that cam sounds way to large for your application. I'm rather shocked they would recommend this cam for your setup. It's more for a stroker engine.

So you think at the present time fast355 that just sticking with the 862 that I'm currently awaiting on will be fine ,I am.hopefull of getting close to the 300cfm mark but they will be fine to also.run the cam motion titan 4 of 5 with what I'm putting together ?

Jones cams Just had a reply from jones cams here is his recommendation
244/254@50
.375/.360 lobe lift
.637/.612 valve lift
114 lsa
Unsure If this is to big but I have read very good things from others on Mike jones and everything points to that he knows his stuff .We are just waiting on some flow numbers for the heads and it may change but he said my compression certainly helps.
