Sounds good other then the intake/tb. It will hold you back for sure. A ported FAST 90 or 92 with a 90mm tb or 95mm like I am using with the intakes inlet opened up to match. When my tb's were swapped from 90 to 95 mm's I picked up 6.xx rwhp and 17.xx rwtq. The larger tb definately helped her breath.

Wow nice set up man I would have to agree. You will still make some nice power, but if you just bought all that get a ported fast intake w/ throttle body then you will see imo about 550 wrhp 500ibs.

could i use the orginal LS2 int+throttlb from a 2005 c6 vette, would that be better or?

Yes but the ls2 intake manifold flows worse than the ls-6-go figure. If you search(since I don't know where) they have a few places that port and seal the ls-2 manifold and it flows almost as well as a fast. you can get them for fairly cheap and I think there is a core charge.

ok so if i take a orginal ls2 int/thrlb and have somebody port it for me , am i then gaining maby 90mm, maby as good flow as fast.?

is it difficult to port this intakes,
how wide is the orfginal ls2 85mm?

ok
thanks
but, tell my, my injectors
i´m not sure what type they are,
it says on them on one side 621030 an the other D1163AA

if i google them i see often lucas something 38lb. and some 40# and sometimes i see 42lb.

but on my other setup, 346ci, tfs 215cc and cam 232/234. 595/598 112l it was often rich of fuel...

so do you know anything about these injectors.

is 38lb, ok on my 402.... whith that setup...

i run the fast 36lb injectors on my 402, i shouldve gotten the svo 42s. My duty cycle on motor gets as high as 87% above 6500rpm. I havent sprayed it yet to see what that does. Wet system

LGM said I would be marginally safe with my 30#svos. Marginally safe wasn't good enough for me so I got the 42#'rs. I think you will need the same.


N/a duty cycle of 87% is nothing, but if you run a big shot you'll likely go beyond 100%. Be careful on how big shot you put on your current fuel setup.

ok but if my injectors are just 38lb, are they not good enough, maby buy bigger injectors, when i buy fast 92mm, and new throttlb. maby next winter????


bu like i said if i google these part numbers 621030 D1163AA they are showing it from 38lb up to 42lb, nobody seemes to know for sure, so how will i know what i´m running, maby when i tune??
