Is there such a thing? some guy in Craigslist is selling a big block tpi intake.

 

From GM, no. But there are a few aftermarket setups... I suppose if you wanted to stretch the definition of TPI there's the Ram Jet 502, but it's really not TPI, more like MPFI.

 

the guy says its an edelbrock big block tpi manifold, but im not so sure if it exists, maybe he thinks its for a big block but its actually for a small block, i hope its for a small block as the price is good, and id like to get it, how would i be able to differentiate from a small block and big block manifold?

 

Sheer physical size should give it away. A big block intake is visibly larger.

There is no long tube runner "TPI" manifold on the market for big block engines. Like mentioned earlier, the Ram Jet manifold could be exaggerated to be called "TPI". Here's a pic of our 454 with Ram Jet manifold.
