Hi , Now and this week we'll start to build my LSX 454 motor in our workshop , It will go inside 2001 Trans Am , The car has full BMR suspension , RPM T56 transmission , Dana S60 rear end 3.54 ratio , Wolfe 6 point chrome moly cage
So the engine details is

* LSX 454 short block CR 13:800
* All Pro LS7 intake runner 280cc Chamber 58cc , Intake valve 2.200 , Exhaust 1.600 , Springs 900lift
*Mast LS7 EFI 4500 intake with accufab 4500 throttle
*Solid roller 27x\28x 8xx\8xx 114

Fuel details

* 60lbs injectors , Fast fuel rails
* Aermotive 340 fuel pump in tank

The car will runs C16 N/A and C16 with the spray through stand alone fuel system , Will install Wilson 4500 2 stage plate system

How much you guess it will pulls N/A at the wheels ?

I'll use this car for street race and it's for racing only from a dig or rolling

What you guys reccomend , if anything is missing please let me know i apprecaite your help

 

Add a dry sump with some good scavenge stages or a vac. pump and let her eat. On motor 720-730rwhp SAE at least is what I would expect if that my was setup.

 

How much the vacuam pump setup cost? and where can i get it from ?

 

GZ Motorsports, around $1000.

 

You'll make some good power with what you have BUT......
Since you're spraying this engine I would've gone with the larger intake runner that All Pro makes.

 

Why are you using the mast intake over the All Pro intake?

 

is not the top HP producer N-A, IMO, and i would keep stroke to 4.00", however who cares that your rings are 0.08 wider, if you want it for comp.
Where you place the shifting points in the design of your cam will dictate your power making ability N-A. For NOS you'll need a 115 lsa or so, again somewhat detracting from your N-A meet range, but hey, 250 shot will have the answer. I will definitely have Patrick G design the cam for the one shot to the top solution, unless you want to try 3 or 4 different cams in quest for the good one. Camhelp@gerragroup.com for $25 bucks is the best deal in high performance today, he will else direct you on the correct parts for the job, so is best to contact him before you start expending, so you just buy it all, ones, i know i gave you info you did not request, but hey, the wise will appreciate it, yeah I'll take a shot, i say meet 740/750whp N-A is in the window. I think for a good shot, compression in 12.00 to 1 is optimal, and still, before you start the new motor have the strongest starter you can get your hands on, cause your stock one will not do, as will take a lil longer to start [in the case of ECM tuning] causing extra fuel injected at start trowing off, the work of your tuner, in every attempt, good luck with your build, take your time do it rite, do it ones....

 

I already purchased the heads , But do you think with my setup and kooks 2 inch headers and nitrous 300HP will runs good ? Or it's important to replace the heads to bigger intake runners ?

Because i seen alot of gains for the Mast 2 piece LS7 intake by Carry , And i think it's the best way to go ?

Yeah you're all right , And thanks for your input , This cam spec'd from Cammotion for those heads and they flows +410CFM @ 800-850lift , I'll email Patrick for a cam and see what he'll spec me a cam , The maximum shot i'll spray is 400HP, Thanks much

 

That intake will work fine

 

Forget to say how about the WS6 hood clearance with this intake and accufab 4500 throttle ? , Or need raised WS6 hood ?

 

You're going to need a higher hood.

 

Do i need to upgrade the brake cyilnder to BMR conversion brake cylinder ? http://www.summitracing.com/parts/BMR-MBK001/
