Default '87 L98 cam choice

Planning stage of rebuilding an '87 L98 and was wondering what others would suggest for a good street'able cam choice. Will probably stroke to a 383, but this is a street car, no drag stip time. Will go with the better GM '128 heads but nothing exotic.

Suggestions???

What are your plans for the intake and exhaust?
Auto or manual? Final drive ratio?

Correction to my initial post: will most likely go with the better 113 heads as I have the 128 heads now.

The car is a manual with the 4+3 trans. Not sure what the final differential ratio is, but its going to remain the stock gears. Plan is also to keep the valves the same as stock, maybe a mild porting / blending by TPIS....not sure yet if it would be worth it.

Will most likely change-out the intake runners but will be staying with the stock TPI and exhaust manifolds. But you bring up a good suggestion...going with some nice long tube headers and changing out that terrible factory exhaust system. Its just going to have to be in the budget to do so....

Had a friend with an 85 L98 w/ manual trans. He used runners and a flat tappet hydraulic cam from TPIS, which made that thing pull like a freight train. I don't recall if he changed the throttle body. I do remember him getting the heads surfaced and rebuilt using valve springs appropriate for the new cam.

TPIS is here: http://www.tpis.com/
