Im wondering if this is possible (i know it would have to be different because of the firing order) or better yet how effective it might be on the less efficient LT1 heads?

The reason I ask is because i absolutely LOVE my buddies Torquer V3. The power curve is awesome (bottom, mid and top end) and the car sounds fantastic. The specs are 231/234 @111 LSA.

Ive never seen anyone ask a question like this so idk if this is a stupid question or not. Just thinking out loud before i go with a shelf cam

 

Since the LS1 has totally different breathing characteristics (heads being a big factor), I believe it would be presumptuous to think a cam with the same specs would have the same benefits in the LT1.

 

believe me i wouldnt be expecting the same benefits... frankly there arent many shelf cams that size for the LT1, so i was wondering if it would be a decent cam. The cc503 (224/230) is considered mild and a gm847 (232/242) is a wilder one. The V3s specs seem middle of the road, but admittedly would need more offset to work well on LT1 heads from what ive learned here. then again, there are LT1 cams that arent that way

 

SBC, BBC, FSB, etc... almost every engine common to racing has played with firing order changes and seen some benefits.

The 1-4 order swap for SBC can show some gains at very high hp & rpms. The LS1 order is similar, but adds an additonal order swap to smooth out the sound.

Swapping firing order, specificaly the 1-4 swap, requires an aftermarket PCM and distributor. The swapping of firing order, which are from opposite cylinder banks, will play havoc with the PCM's fuel trims (due to O2 feedback being grouped by cylinder bank).

there's more hp available out there for a lot cheaper than this. Unless you run open-loop all the time, you'll need a new PCM.

 

He's not talking about the firing order he's talking about the cam specs. And don't buy a cam for how it sounds, buy it for how it performs.

 

If you want LS1 h/c performance out of an LT1, be prepared to step up to the proverbial plate in both expense and work.

 

It's really not that hard to beat the majority of them simce most of them are dyno queens.

 

and lots that aren't.

 

Are you talking about taking the valve events of a LSx and putting them on a LTx core or are you talking about physically buying a LSx cam and installing it in a LTx motor? Using the valve events might be ok, but you won't get the same results as Shoebox has stated because of the heads and design of the motor. Physically I don't know enough about both motors to comment, but my guess would be no it won't work.

 

Im not, i would be buying for how it sounds AND more importantly how it performs. Ive driven his car and the power curve is perfect for me.

Again, I wouldnt be expecting the engine to react to the cam quite the same way an LS1 would. I know LT1 heads are inferior in terms of flow, so the top end would undoubtedly suffer in comparison. Im not expecting it to compare, im wondering if it could still be a good cam setup.

thats another topic but i totally agree.


I am talking about the first... valve events of an LSx cam on on an LTx cam. I know i couldnt use an LS1 cam because of the firing order.

 

simple solution ...... sell the LT1 and get an LS1, there is not much price difference these days with all things being equal. Art
