Im getting my L98 Rebuilt to a 383 Stroker, re-doing the heads, getting new valves (something about swirls on them for better air flow???) 3 angle valve job, roller rockers, diff. cam, hypereautectic pistons

SLP siamese runners, TPIS Big Mouth, Ported/Siamese Plenum, Suncoast Ram Air, edelbrock T.E.S headers, Catco high flow cat, borla 3" adjustable cat-back, Jet Stage II Chip.

Would this set-up be good to run 12's. Have any idea on track times? or even HP numbers

 

Depends on what cam you get. Also you'll definately need a higher stall TC if you don't already have one. What gears do you have?

 

I forget exactly what my stall is, I know its a lil higher,but not much, got a new one when I got the high. perf. rebuild on the tranny.

I have a 3.42 posi 4th gen rear in it.

 

I'd say you're going to need something in the area of 2800rpm stall or so at least. I'm no expert but I don't see you breaking into the 12s with those gears/TPI and not having a high stall TC.

Not too mention those headers (TES) aren't helping. You need something with some 1 3/4 primaries.

 

How about everything previously said, but with the LT1 intake.

 

I'd say you'd need a higher stall with a LT1 intake than a tpi intake...
that's my opinion though
