Ok guys, I have been all over the city and the net looking for stuff for my car, but I keep getting different stories.

What I want to know is: Is my cam roller or not? (I dont have center bolt valvecovers, so I dont think it is.) Is this the 'peanut cam' everyone hates? What are good starter upgrades? I was thinking of getting some 1.6 roller rockers and some new springs (dont know what kind though) and I also dont know if I'd have to replace the lifters if I did this..

A little help, please?

Btw, it's a Canadian 86 Trans am LG4 700R4 with no computer controls.

 

If it is the 86 motor, then no it's not a roller

It's the flat-tappet version of the peanut cam.

As always, the first upgrade for a car equipped with that motor, should be the exhaust, all the way from the heads to the street; BUT NOT FOR LG4. Any piece that bolts to any piece that's already there, will preserve the LG4 bottleneck.

After that, the cam; after that, gears; then head porting. Somewhere along there you need to lose the single-snorkel intake.

 

I'd do that first, since its usually the cheapest and the easiest to do.

 

No.
Yes.
Full exhaust using TPI for the part no.'s (ie. but exhaust for an '89 350 TPI) (like RB said).
Not yet... no.


An 1896 T/A? That's something you don't see everyday (fix it in your sig ).

 

Holy cow.. oops. I never saw that typo, thanks.


And thanks for the help everyone. I guess I'm completely inept at this stuff, as much as I try not to be. Just got nowhere to learn.

 

Ok, well I am looking for an l69 intake, so that will probably happen pretty soon. As for the exhaust, I'm saving for headers (2055s probably) and I have the rest taken care of already.

I think what I'll do is get the headers next, and then get my 350 in there and save the valvetrain upgrades for that. Thanks for the help guys.

 

The manifold? Its the same as the LG4's intake manifold.

You mean the air cleaner?

 

Er, yeah. Sorry.
