Anyone running an LT1 hotcam kit in an SBC? will it work with standard SBC heads (not vortec)?
They sell the kit including springs, roller rockers, retainers, etc., for about $500. The stock GM LT1 roller lifters are another $180 or so. It seems like a good deal, and the parts are proven reliable and durable.
I'm wondering if it would work with a standard SBC with Dart I.E. heads, and what setup might be required with the heads? Would the lt1 lifters even work in a standard sbc?

A friend of mine with a '95 camaro runs this setup in his lt1 and dyno'd 335/343 n/a, 413/508 on just a 75 shot :eek: . I've seen the dyno sheet, and also seen him walk off and leave me on the spray when I had my '02 Z28

The GM roller rockers are only made to fit GM roller equipped or roller rocker ready blocks. I think this is any 1-piece rear seal block or any block thats about '87 or newer. Everything else would work and the lifters would work with any newer block. Maybe get the Hot cam kit and aftermarket roller lifters.

The "HOT cam" is not a "LT1" cam; it was originally for the LT4. FWIW. Although, it goes right into a LT1. But that's not its "name", and it's not all one word. It's the "LT4 HOT cam". HOT stands for something I can't recall exactly, it's not talking about the temperature.

It only fits SBC, so that's the only motor people will be running it in. So yes, it works in a SBC; with any kind of heads you want.

The stock roller lifter will only fit in a 87-up block that has the roller lifter provisions. Most of them don't; truck blocks, for example, usually don't. And if the block won't accomodate the roller lifters, then it won't accommodate that cam, either; at least not without some other adaptations.

The rockers that come in the kit are self-aligning. They do not care what kind of block you run. They do however care that the heads not have any other method of guiding them. The heads MUST NOT either have guide plates, or the narrow slots that fit tight to the push rods; they MUST have large holes where the push rods go through, and no guide plates. Alternatively, you can run any other rockers you want, with any guide system you want, along with the cam. They don't have to be the ones in that kit. The cam won't care at all.

You can get lots of cams from any number of sources, that will run harder than the "buzzword" cam. I wouldn't be too tied down to that particular part. It's a decent cam and all that, for a real mild motor, as you point out by example; but it's REAL mild for a carbed application. It's optimized for computerized fuel injection with minimal computer programming mods, and consequently, leaves alot on the table when used with a carb.

The thing that makes the LT1 run good with it, is that the intake runners are only about 4" long, and the heads have a straighter shot through the intake port, than most "conventional" heads. Plus, GM spent a bunch of time tuning that cam to work with those heads and that intake; it doesn't necessarily translate that just because his car runs strong with it, that your (altogether different) car will do the same.

Thanks. that's the kinda info I was looking for.
Sounds like this probably would be a poor choice for me, at least it would give up alot of power, but that's why I'm researching it now before I spend any money. smile.gif I'm building a fairly tame motor, but I would like it to propel my '69 to some high 12's on street tires, which probably equates to minimum 350hp/375tq at the wheels.

My block is newer than '87, but it's a 2-piece rear main and I don't know if it has roller lifter provisions. How can I tell? I have a GM 'targetmaster' block (made in Me-hee-koe). If so, I might still go with the GM lifters regardless of the cam. They're cheaper than aftermarket, and they are reliable.

I know there are some people here who aren't fans of hydraulic rollers, but I settled on that because they're low maintenance, durable, and I can get the power I need without going solid. I think there's a good reason all the newer GM v8 motors use hydraulic rollers now.

If you have a target master engine, it's a two piece seal, non roller 350. It uses the same casting as an early 70's 010 block so there's no provision for a roller cam unless you use aftermarket lifters designed for non roller blocks. I have the HOT cam kit ($475 at my local dealer) and will be using it in my ZZ4, and the ZZ4 cam will go in my LT1. If I want to upgrade again later on, the LT4 cam will go to the LT1, ZZ4 cam to my 305, etc. and the rockers stay in the Velle. My Chevelle never goes to the track, so it's a nice choice for a driver IMO.
