Nevermind

 

Either buy a factory built CARB certified performance vehicle , , , , Or move to a more performance modification friendly State .....

 

Yeah, Ill get right on that. In the meantime, anyone have some actual suggestions?

 

m not 100% on CARB certification but I feel like one of the big manufactures has to be California legal. if you have no choice but to keep the manifolds and exhaust. I would start with the cat. the factory cat is a horse power death trap. replace it with a high flow cat. there are a lot to choose from now days. I would also do more research on a carb legal exhaust system. there has to be one right?

 

Ok , here's a great suggestion ; Howz about ya take your chevy truck discussion to a Chevy truck forum , seeing how this forum is for 82/92 Camaro/Firebird cars only !

But , I'd still consider moving , earthquakes & all .....

 

Waste of time

Are you allowed to change the "T" pipe to a real "Y" pipe? That is a HUGE restriction.

Edit: never mind - not an f-body.

 

IIRC,those trucks had better flowing iron manifolds than our thirds were saddled with-make up a better "y",high flow cat,larger pipe diameter better muffler-just make it look stock,doubt anyone at the smog station is going to be too picky about a 1985 pickup as long as all the smog parts appear to be there

 

Heads and can will add power.

 

An 85 truck had the same design log manifolds as a 3rd gen. Different flange and exit angle though.

That being said most of the 73-87 trucks had the manifolds that drop down under the spark plugs. Get a set of manifolds for an early 90s 350 van. They will look stock, have smog provisions and have a 2.25" exit.
