Hey guys, ill just introduce myself first. im eric and have been a LONG time camaro buff. but i cant afford one yet....

however ive been actively searchin for a 90-92 with a 350 and a 5spd and im havin a real hard time findin one, in fact i have never seen one in stick. were they just not made, or just made in small numbers?

 

They never made a 350 with a 5spd. It has been said that the T-5 transmission wouldn't hold up to the abuse.

In truth it all depends on how you drive it and how well you treat it. But that may or may not be the reason GM chose not to offer it.

If you ever see a 350 with a 5spd it's not an original engine or perhaps not an original transmission.

P.S. Welcome to the boards.

 

thank you, that makes sense. did the 305 ever come with the 5spd in those years?

 

yes, From 1987 ~ 1992 the 305 TPI was avaialble with the 5 Speed... I personally own an 87 Formula.

The combo of 5 Speed, 305TPI (LB9) and T-tops seems to be a desirable combination around here.

305TPI (LB9) 5spd cars got a better cam then the automatic cars did. If you also got the G92 option with 5spd and LB9 you have quite a find. that would give you a engine oil cooler and a true dual exhaust with dual cats. All in all over 30HP more than your standard automatic LB9 305TPI. Also G92's got a better set of gears. 3.23 or 3.42. I believe.

 

The 305 5 Speed cars got the same cam as the 350 Engines.

IN 1990-1992 for the Firebirds they did some odd things with the Cams & such, SOM of the M5 cars I believe got the "peanut" cam... This is the information I found through the Firebird Parts & Illustration manual.

No ThirdGen ever came from the factory with true dual exhaust. Dual cats YES, but not dual exhaust.

 

164 GTA's in 91 came with the lb9 t-5 (with g92) i guess its rare

figure atleast half of them..have been totaled, torrched, flooded and beat to ****...maybe its more like 1 in 100 ever made..
and my mom wonders why im hell bent on keping it..

L98 cam and N10 gave it 230 horse and 300ft pounds

heres a link for the 91 productoin numbers

You could always do the swap. The 305 is a good engine, but the 350 is just better and is what you really wanna go for, unless u don't mind an Auto.

 

I am sorry. I don't know what I was thinking. You are correct.
