Many electronic design organizations now recognize that problems arising during PCB fabrication can drastically impact product schedules, cause costly design re-spins, and require modifications to the design after release from engineering, compromising design integrity and intent. CAM350 gets PCB designs successfully through fabrication with ease - the first time. CAM350 is easy to learn and use, and its return on investment is instantaneous.
HOW MUCH IS CAM 350 MODS
Use your cam and make the head mods to make it work.and don't forget to check that piston to valve clearance.CAM350 streamlines the electronic product delivery process by verifying and optimizing a PCB design for fabrication. but you have to over look the duration.amazing how a small lift, big duration cam can hit a lick. If the head you have are the 96-98 (think thats the years) i wouldn't put anything else on thats gm stock.they work.and work well.i won't go into the other vortec head 355 at the shop.currently running crate motor stock s been in the 10.80 range with cleaned up vortecs and a dish piston short block and a 465 lift cam. was going 1.60's on small slicks thru the mufflers.the car without the msd & springs went 12.00's.this motor will get it done for cheap.now, on to my combo.383 flattop short block, 518/536 crane solid, and a pair of freshened up vortecs.had the bosses cut and the seats cut for 1.46 diameter springs.also went to screw in studs, to get away from the self aligning rockers.haven't got my intake yet, but leaning towards a airgap or something comperable. off the shelf new from gm, no machine work done, no porting, bolt on.vortec heads.1.5 roller rockers (self aligning) performer rpm intake.750 double pumper.msd ignition.10" convertor.3.73's in a 70 nova street car.went 11.80's this past fall.the heads have had a set of crane bee hive style springs.i raced it one weekend.

355 dish short block (thinking pepboys or autozone reman longblock) with a 488 lift summit cam. You can also use cheap Z28 springs on them, and standard intakes and valve covers. Stock 1.94" valves are usually dirt cheap, so all you end up being out is the cost for the machine work, unless you can regring the seats yourself. Stock they flow about 190-195cfm which is better than the swirl port heads.īest part is that they are usually dirt cheap or free.
HOW MUCH IS CAM 350 FULL
A full port job will get them into the 240's and requires chamber relieving. They will flow low 220's cfm at 28 inches with a good pocket port and filling the divot under the rocker studs with epoxy. They have decent sized valves stock (1.84/1.50) but I usually open them up for 1.94" intake valves, and pocket port them. These are perimeter bolt heads that have good sized runners (about 160cc's) and small combustion chambers to get compression up (53cc on the 601, and 58cc on the 416 is what is listed). Second choice would be casting number 416.

If you are making a super cheap drag car, I personally would try to find a set of early 80's 305HO heads - casting number 601. I would replace the heads with an older set to open up cheap intake manifold and valvetrain availability. If those heads have the vane cast into the intake port, they are swirl port heads and are not good for making power, or much else. I would use an older engine but have had problems finding one cheap. We just want something to run for now and will try to make it faster as time and money allows.
HOW MUCH IS CAM 350 UPGRADE
The plan is to upgrade the engine every year in class.

509 fit with the stock heads? I also have a set of roller rockers for an older 350, will they work? We are trying to keep it on the cheap, remember school teacher. This engine has 4 bolt mains and I think it is a 98 truck. The heads do have the swirl in the intake, but the combustion camber is not the little one I saw for the Vortex engine. 509 cam but read on the web that the Vortex engines can only take up to.

I know older small block stuff but am not up on the late model engines. The kids are building a drag car and we found a late model 350 to use. I am just a lonely poor old high school shop teacher.
