? on Record RWHP on a stock bottom LT1 N/A, Hows 452!
That is what my car put down today at Dyno Tuned Performance in Chesapeake VA. The phone number is on the dyno sheet if anyone needs to verify the numbers. This is a N/A stock bottom end LT1 with worked over AFR LT4 195's by Eric Bradby (E.B. Porting) and a custom cam from Joe Overton (Lethal EFI Performance, who also happens to drive the world's fastest LT1....9.8's ALL Motor) so these guys KNOW there ****~! Together Joe and Eric form TinShed Racing 
Has anyone dyno'd higher on a stock bottom end running all motor because I haven't heard of it. I think Joe and Eric would like to know moreso than myself (course I wouldn't mind either
).
Two links are provided. One for the RWHP and Torque, the other for A/F.

I cannot thank Joe (CZ member), Eric and Quickshotkimber (CZ member and 399 RWHP from the same guys) enough for the help, especially Joe with helping me tune this car OVER the phone!
I OWE you Joe!
If you cannot read the links the numbers were 452.0 RWHP and 398 RWTQ!!!!!!!!!! DAAAAAAAAAAYUM! Virtually UNTUNED she put down 402 but the Borla was capped on the 1st dyno run on the 25th of June. Today the Borla was WIDE open! I will repeat this was ALL MOTOR!!!
EDIT: I KNEW I forgot to post something!................
Those numbers ARE corrected!!!!!!! Brett told me specifically to mention that and I forgot. He knew that would come up.
If ANYONE wants information you need to PM Quickshotkimber he's like their agent or somethin'.

Time to change the sig .
452 rwhp 398 rwtq
VERY nice numbers. I haven't seen higher from any stock bottom-end lt1's, but maybe someone else has. Congrats and now its time to hit up the track. Good luck!

Like you said DAYUM! hey I'm not too terribly far from there. Has either of those places got a website?
EB Porting and Lethal EFI Performance?
I would love to go up there and check them out some time.

I am no ET runner that's for sure but I am more than happy with the power the car is putting down!
I might try for an 11.999999 this fall.

That's ridiculous - kickass numbers man!
I'm curious how the ports have been shaped - there is more than just volume coming into play w/those heads. You guys are definitely breaking new ground.

looks like its the heads that make difference above other stock bottom end LT1's............thats what you get when you pay the extra price for AFT LT4's instead of porting the stock LT1 castings.
congrats on the setup

Looks pretty good
I've never heard of a Dyno Dynamics dynamometer though, who're they? Any idea how that compares to the dynojet 248c numbers we're used to? Didn't see any correction factor listed?
Looks nifty, dunno what you're running, but 450rw/525hp can be had with ~280cfm peak & a relatively aggressive HR. Hope it runs well

Props to you guys!
Now those are more like the numbers I would expect to see from a strong 350 ci LTx motor.
The curious question here is this..... how many who have had nothing but accolades for other efforts will chime in here with their respects?
We shall see but regardless, those are very nice numbers. I have taken on a project for a friend. It'll be a 355 with new components, so that will obviously be a slight edge, but we're looking for 450 rwhp with a hydraulic cam. But before I run my mouth.... let's just wait and see what she does. Needless to say, your project is inspiring.
I have a few question if you don't mind and they don't require specifics....
1) Did Eric port the intake?
2) Is the cam hydraulic and if so, I bet the lift is below .600?
3) Stock LT4 valve sizes or no?
4) Stock throttle body or no?
5) Any idea on idle vacuum and at what rpm?
That's it.
Thanks.
