There are much better cams out there

 

The 212/218 is a great cam

 

I told him the LS1 intake wouldn't increase flow much but it's the room he's worried about. The truck is body dropped and a truck manifold doesn't fit. He got the LS1 intake for $10 bucks on ebay and it fits. Anything is better than a 200k mile 4.3L all iron V6, so it'll do. Plus, true duals are never excessive. All one needs to do is determine where they want peak torque at, then start bending the correct pipe size with some form of a pressure equalizer between the two.

He can get one for under $200, that's why.

 

The hot cam was designed to be easy on valvetrain. It has low ramp rates and not excessive lobes to wear the springs bad.

 

That's one of the reasons I went ahead and did this cam because I don't want to worry about drivetrain wear any time soon, although heads are in the near future now. Another reasoning is if a GMPP engineer designed this cam for their LSx motors to be a street performance cam it's going to get its full potential for it's dimensions. I would rather have gone with a TR224 probably, but didn't want that much lift. In a nutshell, a lot of people are against this cam but it makes great power across the board. I'll have new dyno numbers on spring break once the new tranny is in.

If your buddy is building the motor to rev high why not get a bigger cam that will kill up top? Seems kind of pointless to get a sub-220 cam with a low LSA for a high revving motor. Since it's a sport truck I'd go wild with it.

 

what the

 

comp 216-220 is a good cam to go with on a low stall. i had it in my old chevy and it worked great,. that was with the factory verter stalled to 2400 and a good tune. and it was my belief that the ls6 springs werent any good with cams over the 550 lift. if you are going to go thru the trouble and maybe make a swap later i would go with the 918 springs and do it once.

 

what if you install the larger cam +4. wouldnt that bring the rpm range down?

 

why would people not like it. i ran a lt4 hot cam in my older truck and i loved it,for everyday driving. i would like to know what is better myself?

i agree^^^^
i myself was thinking of using the hot cam myself,people say its a good cam but there is better, which i agree.
but?
running a 212-218 how much lift is to much on a stock 5.3 no head work no springs.
or do i gotta do some springs and push rods with a cam as mentioned above?
my truck is a daily driver in dallas,tx and its a 97 swb 5.7
fixing to convert to the 5.3 but i wanna do a cam swap first while its out.
so i dont want to damn radical because i have to a bit of driving.
thats why i was thinking of using the hot cam myself.
so whats your thoughts.
thanks

I like my cam because it's exactly what I was shooting for. A lower lift cam with shorter LSA and good duration. I knew that I would be killing low end with this cam, but a torque converter was a definite plan for the future.

IIRC, Charlie's cam is low lift somewhere in the range of the hot cam's lift around .550'ish? You still should change the springs, and if you want peace of mind I would change the pushrods as well. They weren't "required" for the hot cam, but I run the motor to 6200 and don't want to even think about the stock pushrods failing.

If you daily drive the truck the smaller cam would probably be wise, but if you want to put in a higher stall the hot cam would most likely be quicker.
