rebuild

this winter I'm gonna rebuild my tpi(130mi)and maybe replace the tranny....here is my set up/goal

1.13s flat tpi
-plan to remove a/c +all power robbing emmisions parts
-gut cat(I don't care about my enviroment)
-flow master exhaust
-hooker headers
-l98 alum heads or trick flow heads
-any other cheap bolt-ons
-3.73 gears
port and siemes the runners
shift kit
good tires

all in all improve air flow and exit

2. Forced induction
-Supercharger-$3k
or
-turbo kit (non intercooled)-$3500

also gonna see what suspension modds i can do

1.13s flat tpi

Easy goal.



-plan to remove a/c +all power robbing emmisions parts

Waste of time, only saving would be weight related, and not worth it...there really is no power robbing emission equipment...unless the 2-3 HP loss of spinning the airpump is an issue.


-gut cat(I don't care about my enviroment)

You should. HotRod responsibly, your kids will be happy you did in 25 years.


-flow master exhaust
-hooker headers
-l98 alum heads or trick flow heads

Trickflows will have much more potential than Al L98 heads.


-any other cheap bolt-ons

2. Forced induction
-Supercharger-$3k

You could easily build a super mild engine, almost to sock specs, add the SC and run 13 flat.


or
-turbo kit (non intercooled)-$3500

Turbos are cool too, but a bit more work to set up than an SC (IMO) and exust options are limited...plus, you can alsway disconnect the SC whenever you want, Turbo cuold be done too Iguess, if you have an electrical/electronically controlled wastegate???



3. some sort of tranny swap
-either t-5 5speed
or
-t-56 6 speed
-keep auto w 3.73s

T5 or T56 (if you have to swap) really is only for the fun of shifting and will do little, if any, to your ET's...and most definitely isn't necessary for your goal.

If I get the t-5 I goin with 3.73's
If I get the t-56 I'm goin with 4.10's

Gears are dependent upon engine RPM range where you make the best power...I/E if your motor work in the upper RPM range, then you want a lower (higher numerically gear) if it a torque maker and works in the lower to mid range, then you want a higher (lower numerically) geared rear...don't pick the gear for what you "want", pick it for what you need.



Whats better for drag racing a auto/manny

Auto for 90% of everyone. Just point and aim.

how does this set up sound?

I don't think you have things planned out appropriately yet, and you need to do a little research on what you want and how to get there...but hey, you'r getting there

well i updated my list...I want to remove the a/c cause it doesn't work properly...might need a recharge and its eaisier to install a pulley...I will gut my cat becasue well I don't have an excuse I'm selfish and don't care about anyone but my self...heck I'd run straight off the headers if i could get away with it...who sells trick flows and do they have and address..I don't wanna run a 13 after i add a blower I wanna do it all motor...then add a blower..the cost of a tranny swap has cut far to deep in the cost of my build so i cut it.

So what exactly are you going to build? I/e a blower motor, Turbocharged, NA, etc...you set them all up differently in relation to cam selection, compression ratio, etc...you also have to keep the bottom end in mind too.

Best to strat with a plan, then refine it, then dial it in...then build it.

What?

They don't really rob power, but whatever. I'd retain the EGR.

Environment

Loud, but gets the point..

Hedman

AFR 195

Not with TPI

Aight.

> good tires

BFG drag radials seem to be working well for me. I've used M/T
et slicks too.

Well, that would require a bit of understanding how it works, and a better concept of building your motor.

You might be getting in over your head. Perhaps you should build a n/a motor, and learn how to tune. Then a few years down the road, try a power adder.

I'd hate to see you detonate a new motor almost immediately.

1.wanna run a 13-on bolt ons
2.12s with power adder or stroker kit
3.wanna retain the tpi set-up
*This is a budget build*
-plan to remove a/c +all power robbing emmisions parts
-gut cat(I don't care about my enviroment)
-flow master exhaust
-hedman headers
-AFR 195
-any other cheap bolt-ons
-3.73 gears
port and siemes the runners
shift kit
BFG drag radials might want something that doesn't wear as fast though!

all in all improve air flow and exit

-why do you recommend hedman over hooker?
-what gears should I get with the tpi set-up?
-what makes these heads better (AFR 195). how much do they cost?
-you said "Then put them on Ebay " after I said port and siamese the runners, waht did you mean?

while rebuilding I might buy a stroker kit as an alternative to the forced induction...what do you think about a 383?


also gonna see what suspension modds i can do

Then forget the power adder

Kind of a waste of time

I'm not a fan of strokers, but I am a fan of power adders. If you go power adder, you need forged pistons.

If you wanna go fast n/a, consider getting a 350 overhaul kit with some high compression pistons. AIm for around 10.5:1 with whatever head chamber you use.

The AFR-195 on a TPI setup would be useless. Ditch the TPI, get a edelbrock commander setup, or something similar.
