My track at BlackBirdBend Speedway is 5/16ths mile slightly banked always dryslick come a-feature time.
Which motor would be the best setup for a b-mod
9:1 comp motor
no msd
882,993,487,441 style heads
stock cast iron 2 or4 barrel
stock 4412 or rochester
weight is 2600 minimum
with a triple disc clutch and 6.00 gear

i was told a good rebuilt 305-350 standard bore motor with good cam is all i need for a track this small. I have several good blocks to start buildin, and was thinking of building a stock 350 good cam motor

The 305 is not even good enuf to pull your car to the track..much less race..go with a 350,it costs the same

Buddy,
How much are you looking to spend... you can build yourself a KILLER motor for around $1500...
Speed Pro Flat tops
good cam
stock rods and crank re-done
good set of heads with 202/16 valves
600 lift springs
claimer pan...
its basically what i ran this year... for BBB i think with the right gear it'd scream
