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)

quicker and to a higher amount. The LS1 cars will nose over at 5200rpm with stock valve springs in there.

Did you mean the LT1 valvesprings? I am pretty sure my LS1 doesn't float the valves at 5200, although it might, just not a noticible amount?

I know you have very intricate knowledge of ICE. Would changing to some new stiffer pushrods and LS6 springs be a good idea for my DD w/ 127K mi on it?

I am kinda worried about the valve springs getting tired and I mechanically over-revved my car once, but never checked to see if the pushrods were all still straight(never a ticking sound, happened 35K mi ago)....
