I was going to buy a BBK throttle body for my car. Is this a good buy or just a waste of money.I have alot of internal mods if that makes any difference.PLEASE GIVE ME ANY FEED BACK!!

Depends on what your internal mods are and what intake you're running... Most guys just port their stocker and save money.. but like I said, depends on your mods.

Even then, I'd probably go with atleast a 90mm TB and intake.. just my .02

EDIT... Just saw I was in the Lt1/4 section... In this case.. I know little to nothing about it..

its not a waste of money, you have to determine whether you need the 52mm or 58mm but they are well worth the money

for a bolt on car, doubt it will do much. Heads/cam/larger injectors/headers than yes

you can bolt on a 52mm but the intake manifold needs to be machined for a 58mm. I would not recommend doing that machine work to the intake while it is on the car but some do.

If I were to buy a aftermarket TB I would look at the ASM unit.

I had my stock bored to 52mm and find that it does not have the idle/surge issues often associated with the BBK and others.

you will need to have your PCM adjusted for more line pressure to the tranny....or tranny failure will not be far behind.

that ASM is a chunk of mother flippin change. holley and bbk are priced competitively well

and to address the bbk surge issue @ idle, all you need to do is drill a small hole into each throttle blade in order to let adequate air flow through so its not being choked out
