ok so here is what I have already. a stock ls1 long block, 243 heads, lq4 intake. lucky me I got them for free... perks of the job... they both need rebuilding the 243 have no valves or springs and I think are .010 warped haven't go them checked yet. the block has a knock maybe bent rod. this motor will go into my 1998 chevy c1500 single cab long bed. looking to hit 400rwhp/400rwtq while trying to stay under $2000 budget. what would be a good cam to stick in this Frankenstein engine? im going to port and polish the heads my self as well. is there anything else I should do to get peak hp/tq? would a larger valve in the heads be beneficial? I will also be selling the 241 heads if anyone is interested make an offer.

If you want 400hp you will need a bigger cam and better intake. What transmission will the truck have?

Martin has some truck cams he just released. Look at the stage 2.

Stage 2 TowMAX camshaft
223/230 .610"/.609" 111+4 LSA

The Stage 2 camshaft was primarily designed with 5.3L & 6.0L displacement trucks and SUV’s in mind. Used in a 4.8L displacement truck or SUV it becomes a very aggressive camshaft suited for 4000+ stall speeds and 4.11+ gears. For 6.0L trucks and SUV’s that will need to tow and haul small to moderate loads this camshaft is ideal. This camshaft will offer large gains in torque and horsepower over the stock camshaft in non-towing applications that would prefer a milder camshaft. This camshaft is also well suited for an even milder 6.0 displacement street/strip truck or SUV as well as a mild LS1/LS6/LS2 powered car.

Designed for: 4.8L-6.0L trucks & SUV’s
Operating range: 1600-6600
Expected HP gains: 45-55rwhp
Stall converter: 2800-4000
Gearing: 3.23-4.11+
Nitrous friendly: Yes
Will pass smog: NO

Don't bother with larger valves, a novice shouldn't be reshaping the ports enough to utilize them and some very good 243s use stock valves.

On the intake a lot of people ASSume a truck intake is bad but it is very close performance wise to the LS6 solidly better than the LS1 intake.

yeah ive been reading a lot on the ls1 vs ls6 vs lq4 intake comparisons. I had one laying around so I thought I use it. the trans is a 4l60e

has anyone tryied this cam yet? what valve springs will I need to get? I heard over .600 lift ill need to replace valve springs every so often.

These cams were recently released so I don't think you will find results but the vendor is well trusted so no real gamble to be made trying one first.

Far as springs, with an aftermarket cam springs should be considered a maintenance item. The peak lift is just one element of cam design, how steep the lobe is plays into things. I would talk to the vendor about a recommendation and how often they want the springs inspected, once you are driving the truck you can check the springs periodically and see when they are wearing out if you aren't happy with a mileage interval or to help you figure out a mileage interval.

I remember Martin saying springs should be checked every 10,000 miles or once a year, whatever comes first.

That's good practice no matter what. Any aftermarket cam is going to stress valve springs more. Especially springs that have a lot more rate - they are more brittle by nature and have to be properly brought up to operating temp every time you drive the car.

With that said, the cam I posted can be had in milder lobe form to minimize the wear on the valvetrain. And don't think of cams as some magic thing. If you know the valve events, you will have a pretty good understanding of how it will perform and drive.

What make the 223/230 111 +4 CAM a Truck CAM? Martin just quoted that CAM form my 1951 Ford Car? Is it the fact that it is a 6.0L and the car weighs between 3500-4000lbs

You probably wanted something mild mannered and in general "truck" cams are mild mannered. He spec'd you the cam he thought was right for you and recently just happened to decide to begin marketing a line of cams at the truck crowd. No need to read anything more into it.
Your car isn't all that heavy but maybe you indicated you wanted to stick with modest gearing/stall and rpm limits. The description is vague because it covers 4.8-6.0l, in a 4.8l it would want 4.10s and probably 3500stall and to turn 6600rpm but for you in a 6.0l it would likely be real happy with 3.42s and I don't know for sure but probably 6100rpm limit would be OK where a low limit like that in a 4.8l might be before peak HP.

what about a 228/230 duration 571/573 lift 112 ls? found one cheap with springs and pushrods.
