AS&M 54MM throttle body 300 obo
Selling my AS&M 54mm TB. i bought it a few years ago but only used it on a car for about a year and then the car started on fire... i have no use for this TB anymore. incase your unaware the stock LT1 intake opening is 54mm so this is the biggest TB you can use on a stock unported intake and AS&M is the only company that makes one this size. this TB does NOT come with the gasket. it DOES come with the electronics.
Re: AS&M 54MM throttle body 300 obo
Yeah its 1 gasket. And if I'm not mistaken your stock gasket will work. Only reason I'm selling is I have a 58mm now with my ported intake... When I had a stock.unported intake I ran this because your stock opening is 54mm.

yep, for a stock ported. this is a AS&M. the AS&M throttle bodys are about as good as it gets. also it doesnt look like those come with electronics, this does.
the ones you see on ebay arent nearly as nice of a design and also require a air foil to flow as nice as this TB.
