so I finally have the money to get my 350.
the motor: its a 350 original tpi motor but the tpi system has been removed. I bought it and im going to rebuild the bottom end and go through it.
basicly I want the car to be my daily driver and have 300hp(ish)
what do you all think id have to do to achieve this from a 350 that I would like to keep TPI. (cam choices, roller rockers,etc.)

I was thinking about getting the crane 2032 grind cam and 1.6 roller rockers.

currently in the car is a 305 tpi so I have the tpi set up already and I plan on getting a new wireharness and 350 ecu.

 

Someday I want to buy an engine just to learn how to rebuild one.

Just need that thing called time. Post up your pics and progress.

Cool.

 

Yeah this will be my first engine build lol gonna learn alot that's for sure

 

Shouldn't need a new harness or ECM, unless there's something wrong with your existing ones. All of that is the same between 305 & 350.

You'll need larger injectors, a 350 knock sensor and maybe ESC module, and 350 chip. Might be worhtwhile to look into alternative "chip" solutions, such as learning to program your own, EBL, etc. Do a little research and figure out what fits your situation the best.

I'd suggest this cam here. http://www.summitracing.com/parts/cca-08-501-8 Should work with mostly stock programming and is of course highly friendly to the unique cam profile requirements of TPI.

 

Yeah currently there's nothing "wrong" with my harness but there's quite a few wires that have been cut/tapped into over the years so I was considering buying a new one

 

pic of the new motor more to come

 

Why don't you just buy a cam to give you the same amount of lift with 1.5 rockers?

 

Times II!!.

 

okay so some updates...I got the short block rebuilt. stock bottom end but freashend up. now the fun stuff...heads and cam. ive decided I wanna do vortec heads and this intake to go with https://sdparts.com/details/scoggin-...-center/sd3816 but I cant decide on a cam. someone mentioned this one to me but its expensive for the whole kit http://www.summitracing.com/parts/cca-k08-501-8 any other options that are more affordable?

 

All that intake does is allow you to use Vortec heads ; to make more poweron a TPI you still need the big tube runners as well
http://www.summitracing.com/parts/sle-20004
for a extra $330 so you are $700+ in

Can make better power for $100 less outlay with a Vortec version of the HSR ( and matching cam )

http://www.summitracing.com/parts/HLY-534-186/

 

You don't need that whole "kit", if your block still has the lifters in it. (can't tell for sure in the fuzzy cell-phone pic but based on what else is still there, they probably are)

About the WORST POSSIBLE WAY to pick a cam, maybe even WORSE than going for "the sound", is by the low bid. Just think about GASOLINE... if you pick a cam that makes the engine less efficient, then you will pay extra EVERY SINGLE TIME you stick a gas pump nozzle in it. Most likely in fact, you will pay SEVERAL TIMES the difference in the cam cost, EVERY YEAR.

Buy the right cam.

Vortec heads with TPI is a mistake. Vetteoz's HSR suggestion is MUCH better. Apart from the pure economics, the properties of Vortec heads (high-RPM capacity and flow) are defeated by TPI; specifically, the "T" ("tuned") aspect of it. TPI's long runners control the engine's RPM range, NOT the heads or cam. It is designed to produce specific effects in the intake tract at specific RPMs, PERIOD. Nothing else you can do to that system will change that, as long as those runners are there. But by the time you buy that $base$ and $$$aftermarket runners$$$ to fix that, you're already over the cost of the HSR.

 

so you think I should do the weiand stealth ram and stock l98 heads with a matching cam?

 

No
use the HSR with the Vortec heads

 

Ahh I see. I plan on upgrading to a hsr at some point but idk when ill have the money. Even if I use the hsr won't I still need that base to use it with the vortec heads?

 

No.

The HSR is its own "base". Doesn't need any of that part of the TPI.

If you don't have money for the HSR, you don't have money for the base and all that other crap either. Wait until you do. Don't put the Stone Age long-runner mistake on top of Vortec heads.

 

Okay I see now, sorry I didn't really have time to look at the details on that hsr in the link I was thinking it was just the plenum n short runners but now that I see it's for the vortec heads ill probly end up doing that. It's cheaper and works alot better. Will my stock throttle body be good enough to feed all this you think?

 

Probably.

If not, eeeeezy enough to change it out later on.

 

true...well looks like a set of vortec heads and the hsr are on the way to my house as of now

 

so a set of "906" vortec heads and a the hsr will be here this week.
what about a cam? I was thinking a lt4 hotcam? thoughts/opinions welcome!

 

Kinda weenie, but at least it's cheeeeep

 

Any other suggestions more then welcome lol

 

so I picked up the shortblock last week. little did I know it would have all new hypereutectic pistons and new rods and be bored .040. also got the vortec heads in the mail a few days ago and the hsr. don't have any pics of the heads yet but ill take some n post asap. check out what I got so far.

 

 

I disagree. The beauty of vortec heads isn't in the high rpm capability, but in the outstanding midrange torque that they produce, which is exactly why they made such a good truck head. With the proper cam, vortec heads can produce great power within the working RPM range of TPI, and can make a great street motor. That said, I don't really think that it's a cost effective option because by the time you buy the heads and the intake base, you could have bought a better set of normal SBC heads and ported the stock base to outflow the Vortec base.

 

Please, don't paint the motor orange like that poor bellhousing...

 

Lol nope that bell housing is off of a 70 chevelle 396 don't worry...it's raw with clear coat now...the way it's supposed to be idk what color to do my motor yet...I was thinking about the old school pontiac blue

 

little update, pretty much decided on this cam lifters n timing chain set http://www.jegs.com/i/Comp+Cams/249/SK08-466-8/10002/-1
gonna order the HSR fuel rails with adjustable FPR aswell. as far as injectors im not sure on, ive been told 24lbs will be good but also told at least 28? some help on that would be nice lol.
these rocker arms http://www.summitracing.com/parts/sc...make/chevrolet
ANY other suggjestions or advice are welcome

 

That cam/ lifter kit says for use with factory roller application, but the picture shows retrofit rollers... which do you need?

 

factory roller, I belive. the pics arnt always a pic of the exact part useually just a idea of what it is

 

Youre right but that picture is way far off from factory setup.

 

well is the description at least the rite one? lol for my motor at least
im going by what the description says
