I ordered a vigilante 3400 converter a few days ago. I see alot of guys running these in the LT1 cars, and dont think i have ever heard anything bad about them. I was just wondering what kind of times some of you are running with similar combinations. I have a 355 forged bottom half 11.5:1 with a AI cam 228/235 on 108 with .613 lift and cnc stock heads. Car is just like it came from the factory as far as weight and suspension goes. I have 4.10s in the rear. I was just kinda curious of what to expect. I would like to see atleast something in the 11s.

 

Guess nobody has a combination similar to mine.

 

So you've got heads/cam/forged bottom end, 4.10s, and an all-stock suspension? 11s are possible sure, but you're losing alot of potential by keeping the suspension stock.

 

Yea im sure there is some ET left on the table with the stock suspension, but i have already got to much money in the car as it is. I really just want a stout street machine. I definitely think it has the power for some 11s, it made 494 HP and 455 lb-ft of torque with a 750 holley and a out of the box Vic Jr, but i dont know what it will do with the fuel injection components. As you stated, I am lacking some suspension, i was just kind of curious if anyone had a similar combination with a relatively stock suspension and what kind of times they were running.
