Hey there camaro guys,
My lt1 355 is in the works at the machine shop. I want to know if anyone has any suggestions to get all the hp possible from my build. Im really wanting to pass that 400rwh. Any suggestions will be appreciated. I will list everything i have bought so far.
Car 1997 SS camaro
Lt1 355
Wiseco pistons - 7cc 413g
6" scat rods 4340 605g
​​​​​Stock 3.480 crank
4 bolt mains
Melling 10554 oil pump
LE2 cylinder heads
Comp cams 230/240 5**/5** lift °110(similar to cc306)54cc
Intake ported by LE
58mm tb
Csi electric water pump
Cloyes 3145 timing set
1.6 comp cams ultra pro roller rockers
Lunati high rpm lifters
OBX ss 1 3/4 long tubes 3.5 collectors
3" SS ORY

Compression on my engine should land around 11.4-
With .039 head gaskets. Could also go with a 0.026 if i needed but engine builder said to go with the 0.039. He said them few points would amount to any hp gain.

​​​​​​Now, i still haven't bought the injectors because im undecided about what brand to go with. Accel 30lb or Racetronix 32lb for the same price?
​​
​​​​​​I done contacted pcmforless or something like that and will be sending my ecm to load a tune.
What else can i do to make sure i pass this 400rwh mark. I dont want to end with 380-390 but if i do i want to known i did everything i could to pass this mark with a 355 lt1. Stroker was out of the questions. Im building this car in one swoop effort and cant wait around and save another six months to have it running.
A4 Tranny will be stock with Yank 3600ss for now till after i break in the engine really slow. Car will only be driven 60-100 miles a week.
Hope there is still lt1 owners out there that can pitch in with their knowledge but most of all their own personal experiences with an lt1 355ci

Thanks in advance

 

looks like you should be there. use solomon for the tune. LT1 PCM Tuning - Welcome!

 

Thanks, im hopping. I see you had similar setup. What numbers did you put down with your setup?

 

have not had the opertunity to get on a dyno. im close if not there. im happy, may try some nos for fun, like a 50 shot.

 

This forum isn't of much help. I realize the lt1 build has been gone through extensively but i wanted to hear from the guys with the similar 355 build. Gona go somewhere else now.

 

yep the forum is slow now days and lt1's are not at the top of the list for very many. 30 lb injectors will work fine. be a good idea to have them flow matched. even new they can vary quite a bit. if you have it dyno'd come back an post your results.
