So that brings me back to my actual question: can a LT1 Fbody be Nationally Competitive in ESP?

Let’s face it even with every ESP legal motor mod a LT1 is only going to do maybe 275RWHP. LS1 cars are doing 290-320 RWHP STOCK and with the full array of ESP legal motor mods can put down probably 350RWHP. I’ve heard of a few ESP cars that claim 400RWHP ESP legal, but frankly I don’t buy that (I’ve been around the LS1 community a long time and outside of this particular car/driver’s claim I’ve never seen a bolt-on LS1 make those kind of numbers).

On top of that a LT1 car is probably an extra 100lbs nose-heavy.

So, what do you all think: Can a LT1 still be Nationally Competitive in ESP, obviously excluding the driver issue? (IMG:http://www.frrax.com/rrforum/style_emoticons/default/wink.gif)

So this would be fully legal, correct: http://www.sdparts.com/product/12534776/19...vroletYLT4.aspx

Also, would a LS1 (and LS1-era T56) swap be legal in a '97?

Well, here's a problem that I see...

Notes: Does not include Inlet Manifold, Exhaust Manifold, Starter,
Flywheel, Water Pump, Ignition or Attaching Parts

GM no longer has the intake in production. Good luck finding one.

I believe so but why would you want an LS1 vintage trans?

I already have the manifold lined up, besides aren't intake manifolds unrestricted?

Sorry if my wording was confusing. I meant to swap in a LS1 motor + the appropriate trans for the LS1 (since as far as I've seen there is no legal way to run '93 gearing behind a LS1 due to the different input shafts).

Yes, but I'm not sure how that would play into an engine swap. I *think* since the rulebook reads that any swap must be done as a unit, you would be required to use the LT4 manifold. Besides, is there an aftermarket intake that will fit the LT4? The new Edelbrock might. I don't know.

I don't know if a modified LT1 intake would work since there are some restrictions on porting as well.
