i just found out new info on this gm hot cam

this guy at advance auto parts told me that i can use that gm hot cam in my car without all the chip mods and head work and stuff...... it seems kinda silly to me that u have to do all that work just to get that cam to work..... he has put that cam in his 350 truck and 1996 caprice car and he told me that it literally supercharged his engine and his vechiles are basically stock.... i dont beleive that u need all those things for it to work. sure all of those things may "improve it like any mods that u do to a car" but it should work fine with the things i have in it.... i dont want to change alot of things.... i know companies make cams just for that purpose which is to give the car an off idle sound.......

Re: i just found out new info on this gm hot cam

companies do make cams for what you want, the lt4 hotcam isn't one of those. that guy at advance told you a bunch of crap. if you want to listen to him that's up to you, but i can tell you right now, your car won't run top notch if you just go and put that cam in there. you can listen to him or a bunch of us all telling you the same thing, it's your decision and your motor on the line.

Comp Cams and Crane are 2 of them and just to re-iterate what he said. That cam is actually designed for LT1 engines and yes it can be used in our engines but you will have to chg the springs and get a tune. Not to mention the intake will have to be chg'd.

call up comp cams and talk to them, they can tell you which cam you need for what you want to do. i don't know of an exact cam off the top of my head, but i do know they sell them.

fearthisgta is correct about the lt4 hotcam, it wasn't made for our engines, it was made for the lt1 motor. the lt1 motor has a mid range rpm designed intake that matches great with the lt4 cam. the caprice that guy said he put that cam in, is an lt1 car.

Re: i just found out new info on this gm hot cam

If you want a plug in and go cam, get an AFPR and a crane cams powermax 2032. You will gain about 10-15rwhp with a completely stock motor. So thats about 20-25hp at the flywheel give or take a few for driveline loss etc.

It is what I would consider a "direct replacement" for stock L98 cam. It will give you a little bit of a boost overall and you dont need to change the rest of the valve train or the transmission.

When you start looking at the LT4 hotcam for example, it will work in a "stock" L98 just your car will run like ass, probably throw codes and you will need to install heftier springs and to take advantage of the increased lift and ramp style, you'll need a better flowing head, bigger valves, and a better flowing intake. I am not kidding here either and neither is any of the other guys. TPI and LTX cams are designed to work at different RPMs and thus have different styles and durations.

The guy at autozone is more likely going by the buttdyno instead of actual numbers from a chassis dyno and the last year L98s were used was 1992 in the F-body. 1996 is an LTx style of intake/motor

The LT1s had more power than the L98s did to begin with anyhow...

Re: i just found out new info on this gm hot cam

Sure does sound different.

Its not "aggressive" but its got a noticeable rumble to it. Throw headers on it and you'll notice a real nice difference.

I was happy with the sound using the stock catback, nice low bass rumble to it at idle and when you floor it everyone knows you have a V8.

Crane cams powermax 2032 appx cost up here in canada was $293 from my local store, performance improvements.

Im sure carquest can get it in from keystone or what have you easy enough.

Re: i just found out new info on this gm hot cam

I really wouldn't be putting a cam in there if you do not want to change anything else. My car has almost everything but the cam becuase once you do the cam your getting into the thick of things. Not to mention with stock parts I don't think any cam you get will work right.

Re: i just found out new info on this gm hot cam

An adjustable fuel pressure regulator is required for the crane cams powermax 2032. Thats what an AFPR is. I used a holley AFPR for the TPI.

When you get into cam swaps you have to remove the distributor, upper and lower intakes, timing cover (which can be a real bit** to get back in without raising the engine some to lower the oil pan), push rods have to be removed, rockers have to be removed, lifters and lifter retainers, lifter "spider", timing chain and timing gear on the cam, whole front of the engine (serpentine brackets, water pump, power steering pump, smog pump, alternator, A/C compressor).

Cam swaps are not something you should expect to do in a couple hours, unless you've got the engine on a stand that is.

The cam will work in a stock engine, with no forseeable problems, just be sure that if you do try your hand at this, make sure you take dozens of pictures, tape/label EVERYTHING and make sure you get new gaskets, RTV and moly assembly lubrication.

I did it all by following the haynes manual page by page, picture after picture, and taping up everything when I did my cam/head swap.

Just remember though you wont see any major increase in buttdyno power until you swap the heads, exhaust and intake along with the camshaft. But to put it plainly it WILL work with a stock engine and an AFPR.

Hope this helps

Re: i just found out new info on this gm hot cam

Will the stock springs handle the lift of the 2032? I know Vortec heads won't handle that lift without new springs.

Re: i just found out new info on this gm hot cam

They should but IMO, I would get new ones. And if you are get the Crane H-11 tool steel springs, retainers, and locks. Those springs are good for .600 lift. The only thing is let the motor warm up before you start gettin in the gas and rompin on it. They tend to be brittle when cold.
