These experiences is what I base my opinion on. He may have had a different outcome if he raced longer then just 1st in a longer distance race.

My Vette has heads and a small cam. I have raced several bolton and stock LS1s at the strip. I have NEVER had one pull on me near the end. If they get the hit, I start pulling on them up top. Modifications change the whole nature of the animal. Would you expect a 325 RWHP bolton LS1 to "start pulling up top in the 1/4" on a H/C 430 RWHP LT1?

I think that the main reason ls1s pull lt1s up top is because of there heads. They are lots better than lt1 heads. Once you change the heads and cam on an lt1 they become completely different.

did I say I did???? im sure changing heads and cam would change its nature, doing the same thing would change my car. Went to a dyno day once and saw a 383 LT1 put down 380 rwhp with a LT4 heads and unknown cam??? Insom in his 00 Z28 raced a LT4 SS w/ spray and custom cam in his 380rwhp car and beat it. Must just be alot of people around DFW who don't know what there doing to there LT1/LT4's????? I NEVER said they are slow/ POS or anything, I said they can be made fast and I was just relating my experiences with racing some around here and how this guy who raced one "may" fair better if he went for a longer distance.

I think the intake is a bottle neck as well. Someone know more on this?

The LT1 intake is not that restrictive. Its actually a very good intake for SBC and SBC2 motors.

As Jeff already said, the intake is not bad. The L98 is the motor that has the bottleneck intake.

The LT1 intake is a very good intake until you start pushing monster power (450+). Up until then it flows just fine. The LSx intakes are better, but that's just because technology goes on. A ported LT1 intake can handle more.

The stock LT1 heads are decent heads, but when ported they can flow 275 CFM. Lloyd Elliot's LE3 heads flow these numbers. With a P&P along with bigger valves and the goodies, they'll murder alot of out of the box aftermarket heads.

Stock vs. Stock the LS1 heads are alot better.

I've seen again and again a stall/gears/cai/exhaust LT1 pull on and wax LS1s. He's a local guy and I know for a fact those are his only mods. He runs 12.9.

Stock vs. Stock LT1s are weak vs an LS1. but you have to remember, the LT1 is pretty much the Gen 1 350 SBC. That's the motor that has been used for so, so many years and there are so many aftermarket parts available that it's rediculous.

I'm getting ready to drop $5K into my LT1, when it's done I hope to put down 400 RWHP with stock ported intake and stock casting ported heads. Then I'm going to add a nitrous shot, but that's later (before you call BS, keep in mind that I get wholesale on ALL parts (cept certain aftermarket hi-po ones), and have all tools and equipment to do this myself).

LT1s are monsters and totally and completely capable of stomping their little cousin, the LS1.
