need to know if a 58mm throttle body is to much air for a stock L98 have a chance to buy a holley at good price
 
Installed a BBK 52mm on my 90 L98 and it is fine. They say that 58 is too large for street, and stock intake.

I don't think it will hurt performance over stock, but a 52MM would be the 'best' choice, and would yield the best performance...
 
58 would hurt throttle response, and youre not even utilizing the original 48mm, so I would recommend against it.

I wouldnt even buy a 52 either.
