welp... someone poured something nasty in my gas tank consisting of sugar, a load of starter fluid (said to be upwards to two gallons of it ), and just a whole slew of combustable things... i left my car in a very busy parking lot in my hometown (sleepy little place) and someone got to it. in the end, the damage included two injector tips literally blowing off into my cylinder and scoring up my wall, 6 other injectors clogged or just bad, one piston shot through and my fuel pump is gunked up now and junk. everything affected, down to the block is bad... never caught the bastard either.

so i'm faced with this delema. i have the opportunity to have my hands on another 305 TPI LB9, mostly complete. i figure, since it's out of the car and on a stand, i could probably beef it up a bit and think about some boltons for it.

i'm learning a lot about engine internals and i'm really good with my hands, but i know i still have a lot to learn. i have no experience rebuilding or building an engine so this will be my first ever.


**cutting to the chase, my question- what are some good basic mods on a highschool grad's budget that would go good with my 305 TPI? i'm not looking for some crazy dragster 9 second car, i'm just looking for a good daily driver with some ***** to it- enough to do a little damage to the ricers and others, sound mean, but wont cost a fortune or take it away from being my daily.

i know a cam would be a good place to start, though i know nothing about them and i've been doing my best on TGO educating myself about them. i'd be looking for something mild... i understand the concept of one but not where to look or anything.

heads? would that be a bit much? obviously exhaust, headers, but thats down the road- i'm talking what i can get out of the way while i have my engine out.



again i warn you... this is my first ever engine build so be kind


i have been searching and i have compiled a bit of a group of things i can do from other people's posts, but any other specific help you could give would be GREATLY appreciated

can anyone give me a hand? among all of the jarble in that post all i was essentially asking was since i have the motor out, what could i do on a grad's budget to give it a little extra oomf?

that and could anyone suggest a good cam for an LB9 305 or direct me to a post where one is mentioned? a search turned up plenty for 350s but not much on 305's. a good streetable cam with no chip tuning required. or explain to me how i could go about burning a chip

What is your budget? Is the 305 you're getting a roller cam engine, or no?
I'd get a cam with intake duration no more than 218, and something like 220-228 exhaust, and lift dependant upon what else you want to do... somewhere from .420-.500. Keep the LSA up, 112 minimum. If you plan to pull the heads (gasket cost now involved, and cleaning more stuff), either you can port them yourself or go with some SR Torquers (I think thats the right name) as those are fairly inexpensive and will work well on a 305. Some headers and porting on the manifold should finish that part off fine.

If the motors got a stock TPI on top then, flat tappet I'd go with a XE256H (#12-256-4) and if its rollor then a XR264HR (#08-501-8), no tunning required with either of them cam's, have used both in the past.

my budget is no more than $900... i have 8ish now but i don't really want to go higher than $900. the 1991 LB9 was a roller cam engine.


i've read the LB9 305 tuned ports like stock lt1 cams with 1.50 rockers i think? cant remember if thats what it was

heads are out of the question at this point, too much money.


i'm just looking to avoid any reprogramming and really extensive work to make a cam fit for the engine.




so for now, i should probably go with a cam? is there anything else i could do for ehh $400 more bucks to get me a little more oomf while the engine is out?

How about some intake work.. Throttle body upgrade couldn't hurt

Check out last month's Camaro Performers. It has an article on "Beefing up the Chevy no one wants." If you can't get a copy, let me know. I'll find mine and give you a run down of the basics. Also, the cats on these cars are very restrictive. A $130 race cat can make a lot of difference. I dunno about the 305, but the 350 falls on it's face due to bad flowing heads and an intake that's restrictive above 4500 RPM, with a weak cam. It's really a trifecta of powersucking on these cars.

well you say your good with your hands... pull your heads off and port them, i did my 305 up and it was my 1st engine build too and i ported the heads, it musta worked because that lil 305 would rev to 6200 when i was racin... and she`d pull 7000 if i was just messin around. it was a 4bbl car not an FI though, port match your intake and heads and get an airfoil for the throttle body, with the new cam that should help alot and not cost to much to do.

thanks a lot for all the response, i've narrowed it down to three major sources where i'll start. i'll start with a cam. the cam hawk92Z recommended for the roller cam type (XR264HR). i looked into it a bit more and it fits my budget and engine application.

i'll do some work to my intake, i'll read up on porting my heads and that should be enough for me right now. cam, intake, and head work


further down the line i'd like pick out a nice set of headers, free flowing cat because as thescaryone mentioned, i know these cars are notorious with restrictive cats. i'll just start small

thanks for all the advice guys, i know where to start and what to start with now

Yea. It sucks with a budget, because even the GMPP Vortec heads that run 170 with a 64cc chamber will use up most of your funds. ($600 from summit) On the plus side, as far as I know, 305 heads can be swapped onto a 350 if that time ever comes. Same with exhaust and most of the other stuff.
Switching out of MFI can be a huge waste of time just to gain some ponies, especially if this car needs the reliability of a DD. And, since you're in NJ, I assume you need to pass emissions, so that really only leaves you with one dual-plane TPI-style manifold for your car, and that's the Accel SuperRam, which is a colossal amount of money. So living with what you got for now would be better. Porting the heads, port matching the intake, siamese the runners, airfoil the TBI. Most of that is free without the cost of tools, and does make a difference.
Also, look around local shops. Maybe they'll have a good deal on something similar to what we've mentioned. Or maybe someone's selling some Vortec heads they don't need for cheap, or something. Keep your eyes and ears open. There's some good deals to be had.

OH! And spend the $20 on a Stant Locking Fuel Cap. :yes:

Sorry to hear about your car being vandalized. I've got Stant locking gas caps for all my cars and if I were you, I'd get one too.
