i realize i am over on ls1tech instead of pt.net but i knew more of you guys know about weight+power= ET's
i have a single cab silverado and here is the build
iron block 347
Diamond piston
Eagle Rods
10:1
228/222 115*
Bogarts
caltrac's 50/50 90/10
Built 60e
342's
60s twin walbro's
kb racing T6 s465 1.10 A/R
circle D 3200
i will be adding either a set of ETP'S or TFS 220's and Edelbrock Pro flo
my ultimate goal is 10.20's. will i need the heads and pro flo to meet my goal? what do you think is realistic without the heads/intake and with the heads/intake and boost level for both. im guessing raceweight is maybe 4400?

as far as 60' goes, i have been low 1.6's on a 5.3 with nitrous and that was before the caltracs and all 4 shocks. the turbo should spool nicely with the 347

i only know of one which is a 370 4x4 single cab and it has self ported 317's
but if it only take 700whp to run low 10's in a truck then its possibly cause i have seen PLENTY of 700+ 347-370 motors make that kind of power with a stock head.

I went 145 with ported 317's at 3500 raceweight, and Harlan I think went 166 with a set of ported 317's or 243's (I think)...
The thicker deck surface of some of the aftermarket heads out there will help with clamping.
I think you run low 10's with the right parts. I went 10.0@140 on 16 psi with my old tired 348cid and 8:1, but I was 3400 raceweight.

now another question i always had would be, if you run stock heads would it be best to put arp head bolts or head studs? the way i see it is if you put head stud's on some heads they are going to crack if you reach the boost level and be useless after, and if you just put head bolts they will just lift and you would need another gasket. can someone explain that one to me,

So it sounds like you and I are in the same boat pretty much. My car is about 4100lbs plus me (280lbs). I have a forged 370 with twin walbros and 60s. Stock 317 heads, CR is about 9:1. My best pass to date is a 10.45@134... getting back to the track as soon as the weather clears though to best that! Oh ya I'm on a 4l80e.
