So I recently decided to hang on to my 87 firebird formula 305tpi for a while after having close to $6,000 in engine repairs done. Now I'm looking for ways to make it fun to drive in the summer...and by fun, I mean smoking tires and beating rice burners at the line. I was looking at getting a throttle body spacer, headers, and a slp cold air induction kit. Are these worth it, or are there other ideas worth considering?

any suggestions are worth considering!

I personally would go with Hedman longtube headers, summit 2-1/2" x-pipe, and flowmaster 1-chamber mufflers dumped, an Lt1 aftermarket intake elbow with some sort of cold air induction, probably custom by me....Holley 52mm tb, stealth ram, and a small comp XE cam 206/212 @.050". Then a 3800 converter and 3.73 gears with some 26" MT ET Street Radials.... Also some Comp 918 beehives with some Titanium retainers. With a custom burnt DIY prom, I think this combo could really run, especially if you stepped it up to the 212/218 cam, and it will still drive nice enough for anyone on the street.

...Then throw a Procharger on it with 14lbs of BOOSSSST!

Or just be simple with a no2 kit

NO2 is Nitrogen. N2O is Nitrous Oxide.
Besides with ONLY N20 it will still be a dog...UNLESS its being sprayed.

Hello, Michael

I'd start by swapping out gears. You can have all the power in the world, but if you don't have the gears to get up into the power range, what good is it? 3.73:1 is a good choice

exhaust (header's to tips), gears, built tranny, stall, cam, rr's, ignition, procharger. done........ kinda like what i have, look at sig.

I think 3.73 would be to steep for him to start out on with a 305. I would go with a safe 3.42

a great way to get more power is to put a 350 in it lol

The power adder forum is for nitrous, superchargers, and turbo chargers only. You need to post in the tech/general or TPI forum for questions about naturally aspirated engines.

if you spent 6,000 you dindt you put in a ls1 or 383?

That is close to what I said, for $6000 you could of bought a crate 350, with much more HP than the 305, but hindsight is always 20/20.

But there are always ways to improve anything.
Exhaust
Heads,
Cam
Super charger or Turbo
Nitrous
etc.

How does your butt feel? 'Cause you just got screwed!

Read my profile to the left. Every bit of this was done for just over $6,000 in the past 4 mos. New motor, rebuilt trans incl. new torque converter, new rear end gears (3.42), Hooker headers, hi-flow cat, Hooker 3" catback, chrome alternator, polished aluminum valve covers, headers coated by Jet Hot, new hood struts, new trunk struts, Alston SFC's, Wonderbar, custom PROM tune. And the engine swap, trans rebuild and rear end were all done by a shop ... $3,100 in labor/small parts (incl. torque converter, new radiator and minor-detail parts like belts & hoses).

I wish you would have posted this before you got your engine work done. But, my suggestion now is to start with exhaust and go from there.

TB spacer: Waste of money with your setup

Headers: Best idea of the three, but will be almost worthless unless you upgrade the rest of your restrictive stock exhaust system as well.

SLP CAI: Hard to find and expensive when you do. Do a search for the home-made CAIs on this board. Just make sure to put your filter where it will actually get cold air and not hot engine air.
