What times

What do you think and L98 with milled, ported and pollished 083 heads, cam, ported plenum, headers and torque converter would run? Let's just say it has average everything else.

That would depend upon the extent of the milling, the extent of the porting, what cam, what headers, what stall, what gears, what was done to the rest of the TPI system, and how well the power is transferred to the ground.

On average...

milled .010, decent port job, SLP 51002 cam, edelbrock TES, 2400 stall, the average 3.23 gears that came with the average L98, and the average TPI unit and base except for ported plenum and your average 245's out back. I'm really just looking for a ballpark number here.

Ballpark? OK 13's to 14's.

If you want to know what it will run, take it to a track and find out. Everything else is just a guess.

By ballpark i was thinkin something more like mid 13's or high 13's. I was just curious if any of you have this same set-up, which i'm sure there's at least a hand full. I would take it to the track, but I'd be pushin it down it!!! My car's actually been off the road for almost 2 months during this engine swap, and I'm just wondering what to expect when I'm FINALLY done.

Nothing like going to the track for the first time and running a new engine, it's a reality check for sure.
