Guess my numbers and times OK everyone so I had a 105000 miles on my stock bottom end and it finally went(like 2 months ago) I ordered up a fully forged 355 to replace it from Ap engineering...they took a long time to build cuz of the machine shop they were using so they are sending me a forged 383 
instead... My car was trapping in the 112-114 range NA with stock bottom end 224/230 112 lsa comp...Long tubes...home ported heads and intake etc...on the juice(100 shot) it was trapping 122-124 spraying it in second or third sometimes(traction issues)...So now that I have the new motor coming I will be upping the shot in the 150-200 range... So with that cam inside a 383 with a 150 shot what do u think she'll be at... rough estimates are fine Im just curious to see what you guys think...I will be getting some drag radials and this is a 6 speed car

Hope you have a 12 bolt or 9 in because I don't think you'll be able to make a pass in the 10 bolt.
11.90@117NA
10.70@128 On 200 Sqeeze
A 383 will make that cam feel stock! Get a bigger bumpstick in there

You have the same cam that I have in my 355 LT1. I'm also trapping in that range. I've hit 115 MPH, but it seems to have been a fluke as I could not back it up (went back to 112-113 on the next passes).
Agree with 94formula/TA, now that you have bigger displacement, the cam will start to feel small.
Going to SAR tonight and hoping to hit 11.9's with my new enhancements to my heads. Car ran a 12.21 last time out in totally horrible weather.
I'd guess that on that big of spray you would break into the high 10's, but that's a wild-*** guess without checking out your car.

yeah I am already looking at some new cam options...I'll probably go with a custom grind...with a widerduration and more lift...and a tighter lsa like 114.....my cam in there now only has about 7k on it too which sucks...I wish I would've known the motor was gonna let go..
