Flow numbers aren't everything... Heck, look at all of the SBF, EFI intake manifolds that are available. Some are crap, others flow. I was in an unsure position so I just sold it. A FAST intake however, should definetly help you with those 6500+ shift points.

What kind of exhaust are you running on the truck?
Is the FM11 on a 114*LSA+4*?

 

you're more keen on this than I
yes its on a 114


Im running a TD setup 2.5" over the trans crossmember into a x pipe and 14" magnaflows

as far as intakes
have you looked into the harrop(sp) setup?

 

Kano, What is your best with the other motor? Let the 6L turn up, mine is up there with the stock bolts. 408 is next for me. I will PM you later.

 

13.8 is the best I got from the 5.3...shoulda been more I think

I got a few tricks still left in the tune that 02sierraz71 showed me today

ill probably start off at 6500 when I get to the track and see what happens from there

look forward to your PM

 

WE NEED VIDEO!!!!!!!! killing "fast" cars on the street is soo much fun. no one around here will race me any more.

a great tool for figuring out your shift points is a gtech. you just look at the g's before and after the shifts. it should be about the same. if the g's pick up then you shifted too late and if they fall then you shifted too soon. with my 6.0 and a 234/232 cam running na my best shift points were around 6800.

 

Could have built the 5.3,what is the matter ,you dont like a challenge?

 

tell me about it
on the street there really not expecting it
but finding cars around here are few and far between

from sotp it feels like there way too low
no g tech but that is good info

 

Is the G-tech reasonablly accurate? With no track and no dyno available I"ve been thinkin I might do well with this $200 investment. Is it a decent bang for the buck? Thanks, Jim

 

I just did a double take on the screen name
good one

 

what tranny are you running on your set up?
