Also my car only has boltons and i,m not planning on doing h/c ever so this mod isn,t needed and as i have found out there are better bang for the buck mods available.

 

I know this sounds subjective, however think a stock 48mm TB with airfoil has much crisper TB response than a ported 52mm TB; unless you customize it with an air foil, it’s a waste of money.

 

There is one right now in the parts for sale with air foil for $30.00!

 

Thanks for all of the input, I ended up buying a ported 52mm chrome powdercoated one of e-bay, also picked up the mated air foil and a polished aluminum tb cover with lt1 logo. I gotta get a tune anyway for my stall and egr + air delete so hopefully it works out ok.

 

i got a 52mm holley tb for 50 bux never installed i took that offer up real fast and put it on in less than 30mins

 

Two and a half year old thread bump, way to go.
