Fastests built 346/347 ls1?
Maybe I can get close to that stock bottom end w/nitrous record if I can ever get my car to 60' with the stick. I'm going to hit it with 200 and try some ideas with the suspension tonight if the weather holds out.

Not as fast as Harlan but I went 8.92 @ 152 with a 347/procharger a couple years ago. Stock crank/block but better rods/pistons naturally. That was with an LS6 intake/stock TB also..
I was thinking about this and had to look something up. I did and ltlhomer ran harlan's old twin kit on his 347 for a while. At 3393 lbs on 28 inch et streets he ran 8.781 @ 161.

sorry, stock BOTTOM END. he has mildly ported ls6 heads and a vic jr with one of their poopy elbows, and a cam. s/d tune, no air filter/ lid. and the car is probably around 3000 lbs. the car runs hard. its actually in a convertable lt1 car. i think he's gonna bump the shot and go for the 5's, then build a 408. 

Def a well built car, take the damn elbow off and itd prolly go quicker. We should be right around that number on a 200 hit once we get the new converter in it.
