Larger Throttle Bodies.

I was just curious if there are any larger throttle bodies that would be plug and play for LS1 FBody's out of trucks or maybe even vettes or is the only way to go up either P&P or aftermarket? - Just curious here is all.

The only plug and play is to use the stock or aftermarket TB in similar size. Just have the stocker ported is your best bet IMO

Most larger stuff got the 4 bolt pattern which is why it won't bolt up.

I bought a FAST 78, which is larger than stock and bolts up to a stock manifold. I don't know that it made any noticeable difference, but sure looks pretty.

The LS2 throttle body is ~90mm.
