I have an 86 trans am LB9 not lookin to go for a 350 or nothin else jus wanna keep the 305 in it and am lookin for suggestions on wat to do to it when i get it rebuilt i have already installed 1.6 roller tip rockers in it and am lookin wat will go good with it any suggestions thanks

Apeiron

What's been done to it already? Why are you getting it rebuilt?

86firebirdta

i got 1.6 rockers jet stage 2 chip bbk fuel pressure regulator and fuel pump jus basic stuff im wantin to put a cam in it and bore it 10 over from wat i have heard is the best way to go with the 305s

Apeiron

Boring an engine when it doesn't need it is a waste of time and money.

Do you have headers on it?

86firebirdta

no that was somethin i was goin to put on when the motor was outside lil bit more room to play around with you kno

Apeiron

Put headers and exhaust on before you do anything else.

86firebirdta

i got a 40 series flowmaster on it i drive a truck everday so the ta is my weekend car so im lookin to do this right now

Apeiron

Have you got a catback too, or just the muffler?

86firebirdta

jus the muffler im wantin to go to true duals after the rebuild i took off my y pipe and started her up and jus sounded like a beast so i think thats wat ima do when the time comes

Apeiron

Not if you need to pass California emissions.

86firebirdta

why wouldn it if you had the cats and mufflers on it should pass no problem

i bored mine over .30 and you can really tell, put a slightly bigger cam, valves, etc. and i beat 350's all the time. boring the motor is a good idea i have mine set up for nos and i run with ls1's. just make sure you have a good flowing set up. headers and exhaust are huge if you are doing cam swap. glad to see someone else believes in the lb9!

86firebirdta

wat would an ideal cam for my car

<3myZ

it depends what you are looking for daily driver, street strip, or track only. but it is important to have all the other components that will work with the cam you want. from heads to headers and even a decent stall converter. there is alot to take into consideration for a proper cam swap.

Apeiron

I doubt you can really tell the difference from boring alone. Boring a 305 .030 over increases the displacement by a whopping 1.6%. Hardly cost-effective when there are sooooo many things you can do a lot more easily for a lot less money that actually do make a difference. Boring is to correct cylinder-wall wear, not to make power.

86firebirdta

jus lookin for a mild cam nothin too big out of the ordinary like i said it has 1.6 rockers in there right now and im jus lookin for a fun weekend car thats got some ***** to it

Apeiron

You only have 1 catalytic converter right now. California won't let you add a second one for dual exhaust.

86firebirdta

i kno that jus when the time comes tho that was my idea for the exhaust was true duals

What ever you decide to do with the cam, make sure you get the heads cleaned, new springs put on and get some screw in rocker studs. The stock pressed in studs WILL come out. It happened to me when I was just learning about this stuff 8 years ago. Mr Gasket makes a good screw in stud that takes less machining than others. Summit Racing part # for these studs is MRG-1076. Also getting a valve job done would be a nice idea while you have them at the machine shop.

Really? I thought there was some way around it with like a cross over pipe or something. I've got the same car as this guy, and even the same color but mine is a 5 speed. I'd like to mod mine up too.
