We have a Chevy 350 that last year was too much power now this year
they have us on restrictor plates it just killed the horses. We have
been trying to get it back, first step was to change rockers to 1.6
and 1.5 no real gain, next we tried different spacer plates and
changed to a Torker II intake with little inprovement. My plan is to
next change the cam shaft from the solid lifter one we now have to a
roller cam to get more lift and duration that we can not get out of a
solid lifter cam. Any info on how to gain our HP back would a big
help. The motor is run at about 6500-7000rpm the timing is at full
advance 36′ with a MSD ignition, Holly 750dp on a Torker II intake
with that dam restrictor plate, we run on a 3/8 mile circle track. Any
ideas at this point cam specs. anything would be good.
Thank you in advace for any help always love to talk racing,
