Like I said is anyone running an LT1 cam in thier ThirdGen, 305 prefered but 350 are welcome. What kind of gains did you see. This is the one I have.
.418"/.430" - 191°/196° - 111°LSA, GM P/N 10243779.

I posted on the general tech, just checking if any tpi owners are running one.

87 Z28 305 TPI, Auto, 2.73, Gutted air boxes, K & N fillters, SLP Airfoil, Dyno Max 3" cat back, Accel 8.8 mm spirals, Accel cap and rotor, Accel coil, rapid fires, and 160 Stat.
Best 15.414 @ 87.47.

 

I do not have the specs of an LT1 in front of me, but I don't think that is an LT1 cam. An LT1 cam had more lift and slightly longer duration than an L98 cam (SD version).

That cam has the same lift as an L98 - SD TPI cam but less duration @ .050.

Also, I believe an LT1 cam had a wider LSA.

But in regards to your question, overall that cam (and even an LT1 cam) is quite mild. If I was going to go to the effort of swapping a cam, I would not put something like either of those. Unless, my original cam was worn out and I wanted a "stock replacement".

 

Two differences between the LT1 and standard designs might bite ya:

1.) LT1 has no distributor...therefore maybe no distributor gear on the cam.

2.) LT1 uses a way-longer timing gear dowel pin. You may be able to modify it to work, as in the LT4-HOT cam where you tap the pin in to the specified depth, but no idea if this is the case.

I responded to your post on the General tech board, but didn't give the specs on the LT1 cam that I'm running.It's .447/.459 lift,.205/.207 duration with a 117 deg LSA.

I'm running a stock LT1 cam in my 350 right now (temporary engine). Yes they have the distributor gear on them. Mine was already modified for the pin on the end when I got it.
