Help On Throtle Body
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..
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.
