im in the process of building a 406 for my tpi 92 camaro i plan on useing a zz4 cam and zz4 heads is this a good combo thanks.

 

ZZ4 cam & heads are small for a 406.

Just my 2 cents.

 

I would research alot of options for that 406 with tpi. You may not like what you find out. A stock tpi on a healthy 406 is not a very good match at all. the zz4 heads and cam are not good for a 406. A set of vortecs may even be too small for that ci. or at a minimum size itleast. The vortecs are probably a 40hp increase over the zz4 heads. Those heads and cam are not anything above average on a 350 but probably reliable though.

 

alright i just wanted some input of what everyone thought, and i guess im just going to build me a 350 with the zz4 heads and cam.does that sound like a better setup?thanks guys

 

Stock the heads are too small - ported they can flow up to 260cfm with small ports for massive TQ (as if the 406 had a TQ deficit...).

Cam is too small - a roller with lots of lift and say 225/235 split duration would haul ***. Easy 450hp with perfect street manners.
