help me out here guys, i got a vortec 350, lt4 hot cam, with crane gold 1.6 RR;s comp. ratio is 9.5:1, which should i buy? the SDPC vortec TPI or HSR?

If your keeping the 2:73 get the TPI.

If u want to go as fast as humanly possible get the HSR.

Been there, done both.

I'm still very partial to TPI though as that torque kick is very hard to beat, t just cant pull up top.

Cant vote until I know more about your plkans and car.

later

will since neither are gonna pass visual unless you plumb the exhaust externally on the vortechs, go hsr, more power capability, less torque, but you can take it right off the 350 down the line and put it on your 406 torque maker!

HSR

can you shave the HSR and get more torque from it?

ok im going 2 list some things that i will have on my car, like i said before iv got a vortec 350, lt4 hot cam, with crane gold 1.6 RR;s comp. ratio is 9.5:1, with a 700r4, going to put 3.73 gears, and 1 5/8 headers, and some suspension mods. and im also partial to TPI, people bad mouth it so much, id like to run 12-13;s and say ya, its gotta tpi im pretty sure that i am going to put the sdpc tpi kit on because i could simply sell the base plate and what not and go for the hsr if im not satisfied, but please post your comments thanks.

I would say TPI since it would be more fun on the street. If your reaching for better 1/4 mile runs then get the HSR. Im running the Superram since it has a little of both worlds. A Superram vortec would be pretty sick.

What kind of numbers would i see from a vortec tpi with stock upper parts, and what would i get with hsr, judging by my parts.

what heads do you have?
personaly TPI all the way. i say we show the other guys what real torque is like
i plan to build one myself. probably 383 with AFR 195cc heads and big cam, i am shooting for 11s.

vortec heads. i might do some port matching and some other stuff but not really to much to the heads, im shooting for 12.s

not much with stock upper parts.
spdc says 40hp over stock w/stock cam.

ive seen guys get 260 hp and 370 tq with my combo

Check out the SDPC site. They have dynoed some different Vortec combos and have the results posted at the following link:

do i have to use the egr with the tpi base?
