Those are the oddball ones. Don't see many of them and some of them are fakes.

Well the GTA was really a luxury package if you ask me. I mean you could get the engines in the reagular TA's, but the GTA had all those nice creatur comforts

You would make some more power if you would get the air filter away from the radiator. It made about a .2sec difference on my old 350TPI in the 1/4. That was when I made a cold air induction system that went out into the fender and feed a 7" K&N cone that was sealed.
Not bad for a days work! and only around $60

hehe, yes I know, thats an old pic just shortly after I installed the TPI. Hey, I beat that price for a cold air, I bought some 4" aluminum dryer vent tubing at Home Depot for $4.98 and a piece of 4" sewer pipe ($2) and connected an old 9" K&N filter I had laying around (free) to the end and made a bracket out of scrap metal and used sewer clamps to hold it all together and to the bracket I made and now its located over the passenger wheel where the stock air pickup used to be for less than $10 and about 2 hours of work, it don't look half bad either

I've got to get some new pics of it up on my site...got some new tall alum. valve covers on there now, looks alot better...

Its rumored that a few 86's got some, mine was one of them... maybe you didnt catch my sarcasm, I put an L98 roller block in it when I taosted the 305.
I have seen two that I know of that were factory L98's and my 305 busted on of theirs a$$es at the Track.
The guy was talking smack and one of my friends set up the grude race against my 305.
Well I won with a 14.6 to a 14.8 and he stop at the timing booth and got his slip and left.
