Hi,

Is there some easy ways to find good jets for my holley 650cfm double pump?

From carb to bottom:
Torker II intake
milled 882 heads some porting and matching done
steel gaskets slight dome head pistons (comp ratio 10.5:1)
289/298 degrees and .475" lift with 1.5 lifters, hydraulic lifters.
3200rpm stall converter.

Engine is at lightened Blazer K5 that is used for sand hill/pit racing. Tyres are 35" Boggers or 33" paddles. Front and rear difs are welded.

My use is way much different than on street or strip, but still I think engine power and tuning is the same.

Thanks

The best way I have found is to use an O2 sensor and meter. There are several threads on this forum that discuss this topic in detail.
