I blew up my TH350 and am going to replace with a BTO Level 2 2004R. My question is I really am not sure if I should go with the 2400 High Performance Street or if I should go a little higher stall. I had a B&M Holeshot 2400 converter but thought it was a little sluggush off the line. Here is my setup

350Ci bored .030 over
Comp Cams XE268H Camshaft (224/[email protected], .477/.480)
Keith Black Silvolite Flat Top Pistons (9.5:1)
Performer EPS Manifold
Edelbrock 1406 Carb (600cfm)
3.55 rear
B&M Holeshot 2400 converter

12 degrees initial timing.

i think the 3.55 gears made you feel a little sluggish off the line with the th350 but i could be wrong.
you could go higher but the cam really doesn't need a lot of stall. 2500-2800 should be fine. remember the stall will flash at different rpm's depending on how much torque your motor makes. there was a lose 3800 stall in my firebird with a 454 and it flashed at 4400 behind the big block.

but you have to drive it so you can put a 3200 in if you want. i tend to like lower stalls. i just swapped out the 3800 for a stall that flashes at 3300 and i'm a happy camper.

the 200r4 has a lower first gear 2.74 so that should help off the line.

i'm not a chevy guy so maybe some will chime in. i haven't owned a chevy in 20 years until i got the firebird with a chevy motor one month ago.

12* base timing is a stock 350 cam at 9.5/1CR

no surprise the motor is sluggish with a 268 cam which wants 16*-18* base and 20 centrifugal all in at approx 2800
