Hello guys

i build big block 509ci, 10.3 compress,
rear gear(stock impala67) - 2.73
th400 with stock converter(stock stall speed)
engine idle^550-650rpm
I have a manifold Edelbrock 7161 range 1500-6000rpm, oval port, Dual plane.
heads: Edelbrock Performer RPM Cylinder Heads 604519
carb: edelbrock 750cfm

when i start - i think that i have small block, wheel not slip. but I dont like hi rpm and camshaft 3000-7000rpm, I only want medium power, because i used car on street every day.

today I have a camchaft COMP Cams 11-407-8(range idle-4600rpm, lsa110, Dur050 Lift: 200/206, 0.510 int./0.510 exh.

i whant buy new camshaft: edelbrock 2263 . Range: 1,500-6,500, Dur050 Lift: 248 int./256 exh, LSA112, 0.629 int./0.643 exh.

Maybe this Cam aggressive ?

WHAT you say?
1. whats will idle?
2. i must replace trans converter? which? stall speed 1800, 2000, 2500?
