I will be running the Mallory Unilite Distributor listed by SS !! For 10.5:1 Compression,you shouldn't need 110 racing gas . Try running 3/4 Reg and 1/4 Premium and see what you end up with ! If you're still not satisfied,buy yourself a 5 gal can of race gas,and add 1 gallon per tank and see how that works !!Had a buddy back in Naples with a DZ302 Camaro with 11:1 compression and it worked for him !!
